Just wanted to let you all know that my sponsor Draxas has just completed the design of their full cat back exhaust system. All parts are made of highly polished high quality T 304 Stainless steel. The main pipe sections are 2.5" all the way from front to back. Here you can see what it looks like mounted on my tC. So far my SoCal tC Club members that have seen it and heard it say that its all good. We haven't had a chance to do the dyno yet to get results for HP & TQ gains but will be doing that soon. Draxas is taking preorders at this time and has more information on their site:

Post any questions you may have here and I will respond to them asap.

looks good but they should put an oval tip like the stock one the big round one doesnt look that great

Forwarded your comment on to them. I have made a similar comment in relation to the tip so we will see what they come up with before shipping out any orders.

:bow: :bow: :bow:

Wow, you really don't get much muffler for $650, huh?
Looks nice, we'll see what the HP gains are, it just looks so tiny!

I just read "Included in the kit is a high flow OBD and EPA certified High Flow Catalytic converter"
So this kit is street legal?

^ looks like it unless the resonator they took off is a part of what makes it street legal witch i think it isnt since it just controlls the volume

<waiting for the dyno>

To answer some questions:

This kit is street legal in the states that do not follow the strict guidelines of CARB. The stock second cat would need to be left alone in CARB states for it to be legal.

Dyno should be performed early next week. We performed one dyno already , but the donor car had run over debris on the highway that SEVERELY crushed the stock S-Pipe (Downpipe) between the manifold and our exhaust. A new S-Pipe has been ordered and will be installed today.

The rear muffler is relatively small, but that is a good thing. Saves on weight. The muffler design we have manufactured does a great job keeping sound down but flow up.

We will have to get some video of the kit on Phillips car.


If you have any other questions, feel free to post them here.

Thanks!

Nikolas

some video would definatly be helpful

Oh, don;t get me wrong, I like the lighter muffler...it just looks funny in that big cutout for the stock one!

MrMeaty,

Yeah, the stock muffler is HUGE... :) Phillip was glad to get that thing off his car. ;)

We were going to replace the damaged S-Pipe, but Phillip emailed and let me know the S-Pipes are on back order until March 21st. So, we are either going to borrow an S-Pipe from another Scion tC owner, or we will re-install the stock exhaust system.

If we re-install the stock exhaust system, then we can compare both the stock exhaust and our exhaust with the damaged S-Pipe. Right now, the dyno with our exhaust on it is of course skewed due to the damaged S-Pipe. The damages S-Pipe isnt letting our exhaust work to its potential.

gotta love polishes stainless! nice nice

Phillip took a short 15 second video of our exhaust on his car:

http://www.draxas.com/movies/ScionExhaust.wmv

It sounds pretty good over the internet...better in person though. The movie file doesnt quite get all of the "deep" sound that is there.


Nikolas

thatt sounds disgusting!!!!!

unless the sound was distorted extremely, i dont like how it sounds at all.

Sounds pretty decent to me but that may be because I had my sub turned up all the way.

I'm gonna agree with aarontrini85, they need to change teh tip. And yeah it's sounds so riced just liek a civic. I'd prefer teh TRD one it sounds lil bit like a muscle car.

I want to see before (stock) and after dynos to do a comparisson and find out wich one is best. I specifically would like to see how the car performs in the 1500-4500 RPM range compared to stock.

nah though... my sub on my computer is pretty good, and the exhaust sounds real good.
good work on that exhaust.

I plugged my headphones into my laptop and that sounds NICE! I like. Now, is that with the busted S-pipe?

This video is with the crushed in S-Pipe.

I learned my lesson a long time ago when it comes to posting videos on the net.... The sound just doesnt carry over very well. But, it is a catch 22... if you dont post vids, people get ____ed.... then when you post them, there will always be those people who dont like it... even if it has been explained to them that the sound in the video doesnt do the sound in real life justice.... Just part of the business. :)

As far as dynos go.. we should have new dynos this coming Tuesday.


Nikolas

Hey Nicolas, whats up? its Guillermo; I saw the exhaust on Phillip's car today over at the Sound Advice meet in Mission Viejo, looks good and sound good too, hey I don't have a crushed S-pipe, if you want a second tC for testing let me know, he he. Hey! when are you making the header?

The sound just doesnt carry over very well. But, it is a catch 22... if you dont post vids, people get ____ed.... then when you post them, there will always be those people who dont like it...


Exactly! :doh:

look pretty good

So far everyone that has seen it and heard it in person has said that it looks good and sounds good. The video doesnt do it justice but like Nikolas said... its a catch 22. From experience there are always those who want to get a V6 or V8 sound from a 4 cyl. kit... its just not possible. For those who do like it and decide to get it I am sure you won't be disappointed. I have noticed since having it on that there is more power throughout the rpm range but quite a noticable difference on the top end. I often hit the speed limiter and have found that in the last two gears I get to the top speed significantly faster than before. I will be doing the dyno testing again tomorrow morning with a swapped out S pipe from my club VP's tC to show the true gains from stock. Also note that Draxas is working on a replacement S Pipe to go with the kits that should give a little more improvement as well. the smallest diameter point on the entire stock exhaust system is actually on the stock S pipe as it goes over the suspension (2" diameter at most). Once that is replaced with a full 2.5" all the way back then the kit will show the best gain in HP & TQ. Draxas didn't have time to finish the S Pipe for my kit due to the fact that they were getting as much done for my ride before the LA Hot Import Nights where my club will be showing 2 cars.

So that is an OBD 2 CA compliant catalytic converter?

I dont like how when u reved the motor high the muffler was moving side to side...i do think it sounds like a riced out civic, i would wait for the TRD catback IMO if it is being made, or just wait for the greddy..until then enjoy a quiet tC :)

So, will the replacement S-pipe that they are currently working be sold with the kit (ie included in the $640) or sold separately? If it is being sold separately, any estimation on price?

^ looks like it unless the resonator they took off is a part of what makes it street legal witch i think it isnt since it just controlls the volume

Where did you get this info? Resonators are for sound not to control volume. The cat, size of the pipe, and type of muffler determine the volume.

wheres the dyno sheets

Phillip has the dyno sheets and is supposed to scan them and email them to me so we can post them on our site....

Now, just like every other reputable exhaust manufacturer who has made a kit for the Scion tC, we experienced the same negligible gains from our exhaust kit. I beleive we picked up around 4whp or so at the top end from our kit.

After surfing around the internet, making some phone calls, it is obvious that we are not the only company that has developed an exhaust kit that is making littler power. After further research on our end, it makes sense. The MAJOR restriction is not in the stock exhaust system, it is in the S-Pipe.

It does no good to install a 2.5" exhaust pipe after a pipe that is narrower than 2" in diameter... This is why we are developing a 2.5" S-Pipe that will be included in our kit. AFAIK, this will be the first kit for the Scion tC to address the REAL flow problem on the stock Scion tC exhaust system.

I have seen other claims to HP gains but I must raise a red flag. The numbers, IMHO, are cause for concern. The only way we are going to settle the issue of who's kit is "better", who's kit makes more power, is to have an independent third party conduct testing with all of the kits, on the same car, on the same dyno, on the same day. This is where I feel Scion Life should step up and cover the costs of the dyno. I will gladly donate one of our kits for this test. Those manufacturers that choose not to participate... that is a black eye for them as far as I'm concerned.

But regardless of all that. These are the facts about our system:

T-304 Stainless Steel
2.5" diameter mandrel bent piping
High Flow Catalytic converter
Straight Through Muffler

Every kit on the market, including ours, makes negligible increases in power..... except one.... that claims to make 12whp.......... You make the decision...

We will have updated dyno runs with new 2.5" S-Pipe from Phillip's car ASAP. Our fabricator is sourcing new flanges that will allow the S-Pipe to bolt to either the stock manifold or the aftermarket headers out there already. This will be a very good test and will show all of us just where the restriction is. I also feel that the stock S-Pipe is why those people who have installed headers are seeing relatively small gains, compared to what is typically seen from installing a race header onto an engine of this size....

It does no good to go from a high flowing pipe to a super skinny pipe into a wide pipe.. that skinny pipe is going to hold you up big time.

Nikolas

I'm glad to hear that you'll be including the s-pipe, I was under the impression that the kit would not include a replacement s-pipe, which was giving CC's exhaust the advantage (since they said they would have one ready when they ship). As for a 3rd party initiating and paying for a dyno comparison, I would definitely be willing to donate my time, money, and car to doing this if someone else were willing to help me with the cost and finding a dyno location. Hugh, or anybody from Suburban Scion, if you're interested, let me know. Or, just anyone in general, contact me here: gradthrawn@yahoo.com, I'm in southeast Michigan, and I travel between Troy, Downriver, and Downtown Detroit on a daily basis. Of course, this is assuming at least 1 other manufacturer were willing to donate an exhaust for the comparison dyno test.

Now,

If the dyno's posted by CC are of their exhaust kit WITH a new S-Pipe, then that gain of 12whp is in line with my expectations of what we will see from our S-Pipe and Exhaust Kit. I see no reason why we wont pick up another 4-7hp from the S-Pipe....

Nope, their dynos are with the stock s-pipe, according to them. What I meant by my post was that they stated that they will be shipping their complete exhaust kit w/ a replacement s-pipe, sorry for the confusion. As for your dynos, will there be a baseline run(s) done with the car stock, and then subsequent runs done with the complete exhaust system on the same day, or will you be comparing the dynos of the car w/ your exhaust system to the stock dynos you took some time ago? I also wanted to know if your results will be SAE corrected as well? It is my understanding that those are key elements to an accurate dyno, but feel free to correct me, I could definitely be mistaken. On a side note, any news regarding headers?

Thrawn,

The next dyno chart we post will have numbers from our first visit to the dyno with Phillip's tC when the car was completely stock, and on the same pic, will be the numbers from our exhaust installed. All of our numbers are SAE corrected (this is an easy way to fudge the numbers if you choose not to use SAE correction). We have been using the same dyno for the past 2 years. It is a Dynojet 248c and is operated by R&D Dyno in Gardena, CA.

www.rddyno.com

Darren, the owner of R&D is EXTREMELY legit in the "sport compact" world.... Darren and his operation have earned alot of respect. We use his dyno because we know it is calibrated correctly (this comes into play too) and we know he is honest.

And in regards to the S-Pipe... I had initially wanted to make the new S-Pipe part of the kit.... then I changed my mind, assuming the kit by itself would make good power, and that the S-Pipe could be a nice upgrade item for those who wanted more power. AFter seeing the gains from just the exhaust, I couldnt, with good conscience, sell an exhaust kit that made only a few HP. So, I will include the S-Pipe in the kit, and probably only raise the price by $20-$40. I still think this places our kit very compteitively with the other ones on the market. (Assuming the S-Pipe gives as much power as I think it will)

Header.... this is on our 2005 product development list. We are beginning work on our Mazda3 4-1 Race Header at the moment... I hope to have a Scion tC header out by this summer.. Being the small company that we are, we cant afford to have too many projects going on at once.

it looks cool, also it is a catback, not an axleback...

If I'm not mistaken it's a violation of federal law to remove or tamper with a properly functioning catalytic convertor.

SimpleSpirit,

That would be correct. As a company selling a product that removes the properly functioning cat, it is our responsibility to make it clearly known that by installing our part, the individual will be installing a Non Street Legal product onto their vehicle, and that they would be subject to any fines associated with such an action.

If we deceive our customers by not stating our exhaust is "For Off Road Use Only", then we can be held liable for fines.

Nikolas

Oh, so the new S-pipe removes the center cat?

Mr Meaty,

There are two cats in the Scion tC exhaust system:

1 in the manifold and 1 after the S-Pipe

Our exhaust system replaces everything up to the S-Pipe, and new as of today, our kit will also replace the factory S-Pipe with a higher flowing 2.5" S-Pipe. You will still have the main cat in the manifold that a Race Header would replace.

Nikolas

Oh, I see. So, there wont be a baseline run again but it will be the same car, on the same dyno, and SAE corrected. I guess it would only be accuracy issue if the results weren’t SAE corrected to adjust for temp. differences etc. Looking forward to seeing the results and your upcoming header.

As an aside, one of my biggest concerns is how the exhaust system will sound with a race header replacing the stock manifold. A while ago, someone posted a sound clip of a tC with an intake and TRD exhaust after they installed a DC header and it sounded horrible. All of the deepness of the TRD exhaust had been lost, even according to the owner. I'm hoping that won’t happen here.

hey whats up draxas vp... im in the same club as phillip and i live in lancaster.. i have a question.. would you guys be able to do a custom exhaust?? i want the s-pipe and the whole catback but without the muffler.. i have a seperate muffler that i would like to use... i was wondering if that was possible?? it doesnt even have to be mirror polish or anything.. i just dont really want to go to eastside muffler, and since you guys are making an s-pipe, i might as well ask lol

Thrawn,

I would imagine that the exhaust note, after installing a header, will get much louder and potentially raspy, depending on what you have in the rest of the exhaust system. At a minimum you would probably need to run a muffler and a resonator.... and maybe even a high flow cat in the mix. Running all three should keep the sound and rasp down as much as possible.

Nikolas

Bump for my question

Nikolas,

Any chance we can get the exhaust and s-pipe to run some tests and write a review?

Quick

I'd like to say thanks to Draxas_VP for how your addressing everything. You seem to be more concerned with doing good work and being honest than geting every cent in profit. And your being patient with everyone's questions and keeping up with the thread. I'll probably go with Draxas for my exhaust even if your set-up doesn't put out the most hp. Hopefuly you're not just a good actor. :silly:

Aside from the tC headers, are there any other mods you have planned for the tC?

Few questions:

1) Does it rub on the bumper or any toher part during revs and driving?

2) Does is rattle druign revs and driving? (video was a little scare with that shaking)

3) Any option for a grapefruit shooter muffler?

4) With this exhaust system and a header would the complete exhaust system be replaced?

5) Chances of install pics? And dyno run videos?

6) Any chance that once its release they will offer a group buy for scionlife members at a discounted price?

Thank you for your time!

^^^^^^^^^I just saw your sig, and was wondering how you liked your tc in comparison to all of those subarus that you previously owned. My final car choice was down between a WRX, and a tC. Ever since I made the decision to get the tC, I have always been wondering if I had made the right decision.

wrx -> fast as f*** and so much potential and like 60 horsepower ready to be released with simple mods. Eats gas, doesnt ride smooth, and other things, overconfident.

tc -> small comapct car with potential as well. Love it lots, I like it mor than my wrx, I miss the speed but the auto up/down, sunroof, coupe, cool look, color choice, quality of interior, exterior, options really makes me happy. If I had to choose between a wrx and a tc new id go with the tc again. Save lots of money and I bought mine used so I could tell its been beat after driving it a bit. Its an expensive car to own, lotsa maintaince and lotsa money spent on gas and stuff. But its hella fast!!! I plan on getting one in a few years again and making it more of a rce car weekend driver type of deal. Probably will get an sti that time.

and p.s. i was debating sti vs legacy gt vs scion tc and I chose the scion! Saved me a ton of money and I love it! Happy to drive it every morning!

Picked it up alst wed and 410 miles already! break that baby in, did 100 miles today! woot woot

thanks for the info, i think i made the right choice

thanks for the info, i think i made the right choice
I agree. I was looking at a used WRX that was only a couple years old and it was nothing like the brand new one I test drove. It sounded like it was in bad shape, and it felt like it was falling apart. And since, stock, there is no mesh in the hood scoop, the one I saw had all sorts or rocks and dents in the top mounted intercooler! I deffinately think getting the less expensive tC and putting money into it is a better choice. But man, that AWD is grippy as hell!

i think that this catback exhaust would be better than any axleback in the market...

I'm pretty sure that all cat-backs would be better than all axle-backs made... unless the company really screwed up.

Few questions:

1) Does it rub on the bumper or any toher part during revs and driving?

2) Does is rattle druign revs and driving? (video was a little scare with that shaking)

3) Any option for a grapefruit shooter muffler?

4) With this exhaust system and a header would the complete exhaust system be replaced?

5) Chances of install pics? And dyno run videos?

6) Any chance that once its release they will offer a group buy for scionlife members at a discounted price?

Thank you for your time!

To answer these questions...

1) Does it rub on the bumper or any toher part during revs and driving?

No it does not rub on anything. It uses all of the stock mounting points and hangs in the same position as the stock tip.

2) Does is rattle druign revs and driving? (video was a little scare with that shaking)
There is no rattling during revs at all. The kit uses all the stock mounts (including the rubber hangers) so there really is nothing to rattle against.

3) Any option for a grapefruit shooter muffler?
That just doesnt even sound attractive to me at all.

4) With this exhaust system and a header would the complete exhaust system be replaced?
Once they do the header work... yes the entire exhaust system would be replaced.

5) Chances of install pics? And dyno run videos?
Install Pics are at the beginning of this thread. Dyno video is possible but it would be different numbers now that I have a K&N Typhoon CAI installed. (Installed last Thursday before the LA HIN show)

6) Any chance that once its release they will offer a group buy for scionlife members at a discounted price?
This point would have to be discussed with Nikolas but I think the price he quotes is already a very reasonable price for the kit that is being offered.

Hope that helps.

Nikolas is a clean character. I have run into a number of shady groups on my quest to find good vendors to point my club members too. Draxas from what I have seen puts out a good quality product and is there to answer any questions or concerns all the way through the process of getting and installing the new kit. I am very picky and my club members know this. I would recommend Draxas products to anyone interested in what they offer.

Thanks for your answers! I like it alot, but $650 is a hole in the pocket. Lol. We'll see how much $$ i can spend once its released, I really like it!

lol i just wanna know if i can buy it without the muffler lol itll be quite a bit im looking to do it

I will attempt to answer all of the questions that have been posted in the last few days. If I miss any, please let me know.

We will more than likely offer an introductory special price on these kits for a couple weeks. The exact discount has yet to be determined.

Once we have the new 2.5" S-Pipe ready to install, we will re-dyno Phillip's car to show gains from using the S-Pipe and our Exhaust.

When we release the header for the Scion tC, you will be able to replace the ENTIRE exhaust system with Draxas Parts if you so choose. How the exhaust will sound is yet to be seen, but I know it will be loud. So we may offer an option on our exhaust for an extra resonator. But we will not start offering that option until the headers are ready to go.

The exhaust that is on Phillip's car and in the videos is the first prototype. The production quality kits will have tighter tolerances and a slightly better fit. We will take new pics once the production pieces are ready.

TCTunerz.com is more than likely going to become a distributor of our products. We will be sending them a Scion tC Exhaust Kit to install and review once we have the kits manufactured.

Thanks!

Nikolas

Please don't let them distribute your products!!! They have a REALLY, REALLY, REALLY bad reputation in the TC community, and will probably prevent alot of people from buying your product. Try to go through a distributor with a good reputation such as trdsparks.com or mcgeorgeparts.com but not tctunerz!!!

TRD Sparks and McGeorgeParts have yet to contact us about becoming a delear for our products. All they need to do is send us an email or give us a phone call and we can work something out. If you want them to begin offering our parts, shoot them an email and encourage them to contact us.

As far as TCTunerz.com goes. If they provide poor customer service, that will reflect negatively on them. The quality of our parts will speak for itself. It will be the responsibility of each distributor to offer excellent service, or else customers will go to those distributors that do provide good service.

This is the first I have heard about TC Tunerz having a bad rep though.

The first three threads you linked were started by the same person over the same issue that eventually got resolved. The last one apparently was the fault of the person not tCTunerz because he didn't complete the order right and they had no record of it.

I personally ordered Randode's Cold Cathode's from tCTunerz and received excellent service. But from that experience it seems tCTunerz just acted as a gateway to the seller since Randy shipped the lights himself not tCTunerz. So how many products do tCTunerz actually ship direct?

^^^ those were just the first threads I found bc they were ordered by date, but I personally have seen countless threads about their sub standard practices. PM Ikonxone for mor info on their shady pracitices....

Thanks for keeping your reply civil. I respect that.

I'm sure IkonXone has great reasons but that seems to be the only case where the problem wasn't resolved. Some businesses are slow, some have crappy response times on emails but other than IkonXone, is there anyone else who was cheated out of money?

I mean all businesses get bad reviews from customers from time to time, but overall those seem to make up a small percentage of overall service. I'm not trying to start a war here but whenever tcTunerz is mentioned, all that is brought up is IkonXone and what happened to him a long time ago between him and Quick. Besides in these days, I prefer to handle things with lawyers and banks than by calling for a public ban on a message board because they took extra time to ship me a product.

tc tunerz isn't bad at all, I ordered a few things from them and it came to my house in less then a week.

how much hp gains this exhaust system? (by itself)

does the stainless steel exhaust that creative compacts it is the Draxas exhaust system?

Once we have the new 2.5" S-Pipe ready to install, we will re-dyno Phillip's car to show gains from using the S-Pipe and our Exhaust.

For the second question. Are you asking if CreativeCompact's exhaust system is Draxa's system? Then no. They are two different companies with two different products.

so... where can i get the draxas exhaust system?

Revilo,

To answer your question. Our exhaust gained about 5 HP at the wheels... We Are now choosing to include a new S-Pipe as part of the kit which will increase power more. We will dyno the tC again once we have the new S-Pipe in place.

Also, as long as a particular company continues to claim their kit gains 12whp, then our numbers will look low.

Nikolas

Our exhaust gained about 5 HP at the wheels


ouch. :(

Our exhaust gained about 5 HP at the wheels


ouch. :(
That's before the s-pipe. It should improve the numbers once they get the new dyno up.

Our exhaust gained about 5 HP at the wheels


ouch. :(
That's before the s-pipe. It should improve the numbers once they get the new dyno up.

I don't know if it really will, though. When I was under my car doing the header I took the liberty to look at the s pipe and mine didn't have any crinkles in it and looked quite large, so I honestly don't see any gains coming from a new s pipe. I also called a reputable exhaust shop (Andy's muffler & racing, everyone in gwinnett gets their exhaust done here) and asked if they thought a new s pipe would improve the performance, and they said probably not.

well at the beginning of the spipe it looks double walled but all the way through i beleive the s-pipe is 2 and an eighth(sp?) from there there it is pretty close to 2 and a half as it goes in to the resonator and from there on out it shrinks again.. so its possible

We'll have to wait and see what the new dyno numbers will be once we get the new S-Pipe installed. From our measurements, the S-Pipe narrows down to around 2" or so, inside diameter of course. Granted, the stock exhaust manifold is VERY restrictive.

Also, Draxas is becoming a Gold Sponsor of Scion Life, so now I dont have to feel guilty when I talk about our products here on the message boards. :) Hopefully the rotating banner ad will get us a little more exposure in the Scion community.

Does anyone know what the whp gains have been from the various race headers out there? On our 2.3L Focus we picked up 12whp from a 4-1 race header..... So if the Scion's 2.4L engine is picking up much less than that, then it must be due to the S-Pipe.. (This Focus also had a 2.5" exhaust installed and CAI)

the few headers out for the tc are getting about 8-10whp. (about the same for torque)

how many hp are expected after installed the s-pipe?

Well, I have already been wrong once... in regards to what I thought our full exhaust would gain... So Im going to play it conservative with the S-Pipe.

I would imagine we will see about another 3-5 HP gain from the S-Pipe.... More if you already have a header installed.

I really wouldnt see why gains of 15-20whp arent doable with full header, S-Pipe, and exhaust..... Unless the cylinder head doesnt flow that well stock?

why make a system that isn't a straight through design? Any bends kinda defeats the purpose IMHO.

i think it sounded pretty good

Motozen,

What do you mean..... no bends?

:confused:

I just hope the final exhaust including the s pipe and a different tip will be completed sometime with in the next 3 or 4 weeks with some good dyno sheets. ... I’m ready!! Keep us posted!!

quick question nick when is the high flow s pipe comin being released

Thanks for keeping your reply civil. I respect that.

I'm sure IkonXone has great reasons but that seems to be the only case where the problem wasn't resolved. Some businesses are slow, some have crappy response times on emails but other than IkonXone, is there anyone else who was cheated out of money?

I mean all businesses get bad reviews from customers from time to time, but overall those seem to make up a small percentage of overall service. I'm not trying to start a war here but whenever tcTunerz is mentioned, all that is brought up is IkonXone and what happened to him a long time ago between him and Quick. Besides in these days, I prefer to handle things with lawyers and banks than by calling for a public ban on a message board because they took extra time to ship me a product.

just some fyi:
what i talk about is not just one case. it is in the muliple hundreds that varies from different boards and even some people here.

Hey everyone,

We are bringing Philip's car back into the shop this coming monday. The goal is to complete our prototyping of the S-Pipe during this visit.

The reason it is taking us long to create these S-Pipes is due to the high quality standards we set for ourselves. We need to make sure the flange we use on the entrance to the S-Pipe is machined properly to provide proper sealing for the stock donut gasket on the manifold. It would be easy for us to weld on a flat flange and jerry rig something to work. But that's not how we do business.

We want to release these kits ASAP... I think the Scion tC owners who purchase our kit will be as pleased as the Mazda3 owners who have been clearing our inventory out every couple of months. Look for another update in about 7-10 days.

Thanks!

Nikolas

nick quick question would the new s-pipe help resolve the issue with the CEL that everyone is gettinf from dc sports or megan racing headers?

lol yeah if they incorporate the anti fouler trick!!!

Correct.... We will incorporate a deeper O2 Sensor bung that should perform the exact same purpose the Anti-Foulers do... removing the O2 Sensor far enough out of the exhaust pipe, thus preventing the CEL from coming on. However, I do not know what effect this will have on cars that still have the stock exhaust manifold, so we will more than likely test this on Phillips car first.

Nikolas

looks and sounds good imo

lol yeah if they incorporate the anti fouler trick!!!

With all due respect, your always have something negative to say??? WTF man?

i did the spark plug anti-fouler trick on my car and it currently has the stock header on, no problems at all. just waiting for my header now.

With all due respect, your always have something negative to say??? WTF man?

I guess in some instances, yeah I do, but in this instance I knew that the only way they could eliminate the cel was to implement the anti fouler trick, or some adaptation of it... shoot I did it on my car and it works like a charm!
Sorry if I came across as being negative, but I think this will be a great mod if they can make some good gains out of it.
$hit! I'm being negative again!

Maybe it was just me, but it just sounded negative smart ___ like, know what i mean? Dont mean to offend you by the way.

*sigh* Missing my baby... the Chevy Malibu rental just aint the same as my tC. Can't wait to get her back. Looking forward to the new S-Pipe and tip being on. Will go to get new dynos run when I get the car back so you guys can see the gains asap. Some complete pics and a new video clip will be taken when the kit is done also.

Phillip is picking his Scion tC up this morning with the new high flow S-Pipe installed. This now completes the package of our Scion tC Exhaust Kit.

He will be dynoing his tC around 1:30pm this afternoon. We expect to post results late this evening.

At this point, we are about 4-5 weeks away from having kits ready to ship out. If you are interested in placing an order after you see our new dyno numbers, please go to our store:

http://store.draxas.com/detail.asp?Cat=&Sub=&Item=520#

Your credit card will NOT be billed until we are ready to ship the kits out to you.

We have changed the tip to an angled cut, double walled, stainless steel tip to better match the curve of the rear bumper. Expect new pics of the system/tip to be posted tomorrow or maybe even later this evening.

If you have any questions for me, please post them here or email me at:

I can't wait to hear it.

I can't wait to hear it.
There is a sound clip on that sales link he had. Sounds nice. However, i don't like the wobble.

I would rather hear it in person.

I'm sure the stock exhaust wobbles too.. it's because when the engine hits the rev limiter it is essentially rocking rapidly back and forth on it's axis which pushes the whole exhaust sytem backwards and forwards

Oh, so it's only when you hit the limiter? That would make sense because the video did not wobble the whole time.

I think he's talking about the wobble in the sound.

Oh. What I dont' like is how the muffler physically wobbles when it revs up.

I think I will have to take a new video of the exhaust.. ;)

When Phillip hit the rev limiter, that is when the exhaust moved. Im sure that even a stock exhaust system would move around quite a bit. If you havent seen what happens to the engine when you hit the limiter (especially when the transmision is in neutral), then take a look at a friends car. The engine shakes rather violently. :)

Damn, then I guess I should stop playing the "How Close Can I Get to the Rev-Limiter" game every time I'm driving. lol :lalala:

Wheres the dyno results from yesterday afternoon? :)

Thanks for the clarification. None of my friends have Scions, and no one has driven my car without me in it, so I haven't had the chance to look.

Wheres the dyno results from yesterday afternoon? :)

I have yet to hear from Phillip. I havent received a phone call or an email from him yet. Usually he emails me the details of what happened, with a scan of the dyno sheet....

Once I have the details, I will make a post here...

Nikolas

we are still waiting for the dyno from Phillip's car w/the s pipe and exhaust system!!!

I will have the scan from the latest dyno posted to our site later this afternoon. Phillip never emailed me the scanned image, so I had to wait for my hard copy to arrive from the dyno facility in the mail. :(

So, on to the news... The S-Pipe provided gains of around 2-3whp compared to without the S-Pipe. This is at the lower end of our estimates that were provided. Now, we will be sourcing a header for Phillips car, most likely the Alphawerks header, from RacingSolutions.com

This will allow us to test the complete package:

Cold Air Intake
Header
S-Pipe
Exhaust with High Flow Cat

It appears that the S-Pipe will be a modification for people to make who plan to install, or already have installed, a race header of some kind. The HP returns to $$ spent on the S-Pipe dont make sense unless you have the header. THe factory manifold is still the most restrictive part of the entire exhaust system.

In light of these latest tests, we have broken down our Exhaust offerings for the Scion tC in this way:

Exhaust Kit: $599
Exhaust Kit w/S-Pipe: $699
S-Pipe: $150

When I hear from the fabricator that he has parts ready for me to take pictures of, I will head over there and snap a few new pics for everyone to see. The S-pipe is a very nice piece:

Factory style entrance flange (CNCed out of stainless steel)
OEM Fit Quality
2.5" mandrel bent
High Polished Luster Finish
Anti-Fouler Included
Lifetime Warranty

If you have any questions for us, please post them here or email us.

Nikolas

so the hp gain for this exhaust would be arround 10 hp including the s pipe? and when draxas is going to realease the race header for the tC? still waiting

when you are planing to do the dyno with all the mods? (int, hea, s pip, exh )

We plan to get Phillip and Nikolas the Alpha Werks header by next week so they should be able to dyno shortly after that.

"Anti Fouler included?" What's that for?
Is this going to throw a CEL? Is this legal for street use?

It will only throw a CEL if you have an aftermarket header. Thats due to the header, not the s-pipe. The anti-fouler will be included so that if you DO have an aftermarket header, it will already have the fix built into it for ease.

Sweet! That's a very nice touch.

Indeed it is! We are taking pre-orders on the s-pipe at http://www.racingsolution.com/products/Scion/TC/1198/SciontCHighFlowS-Pipe

what about the Draxas race header for the tC?
