TC Dual Exhaust!! [Archive]

Its my car. Its turbo. The exhaust system is single 3" from the catalytic all the way to the rear crossmember, where it splits into dual 3" . It is very quiet. It actually has three straight through mufflers. one is located in the center of the system. It will be available as a single tip system, for those of you who don't want to cut your bumpers. It is strictly for turbo charged and super charged tC's. I developed the system to compliment the turbo systems that will also be available. I will have a 2.5" system available for the naturally aspirated guys out there, which will also have the dual or single out choices. The single systems are also easily upgradable to dual by changing the rear section of the system. When they go into production they will be available from TcTunerz. Pics, pricing, and all specs will be posted when available on both www.ScionSpeed.com and www.TcTunerz.com .

"Too bad there not fast"

Define "fast" if mid-high 5 0-60 and low 14 1/4 is not?

Well I have no problems pulling a good 1-2cars on modded ones. I have yet to "test" out the 04+. I heard the 2.2L really overpower the old 2.0L.

Sounds like a real quality exhaust system!!!!
Part of the quietness is that huge turbo you got. haha

Anytime you want to test products on my moms car PM me. Seriously. :)

i can't say "dual anything" looks nice. some people don't deserve dual. believe me i'm in one of the top "put anything i see on my car". i.e. "spinners" --that are really hubcaps, "fart cans" @ 10mph--no lie, wings taller than the car, etc., etc. i can't stand when the exhaust pipes prorude from the same muffler. aren't they suppose to be separated, like the tC that started this post. i'd love to be able to get that setup, but most likely that would mean that i had too much money on my hands.
but it's definetly a setup i envy, can i get a sponsor? :lol: :roll:
:wink: once i get the tC. :wink:

Looks nice, however there is nothing that screams rice more than a dual exhaust on a 4cyl enginer - you have a single header - putitng dual exhausts on a car with a single header outlet is retarded.

Just my opinion though, looks great :)

Whoa dude. You're obviouslly really special cuz "all the people you hang out with have SRT-'s and Evo's" *applause*. Anyway, my point was merely that "4-bangers" do have potential- as recently seen in such cars as the STi, Evo, and SRT-4. Not that you wouldn't have to dump a ____load of money into a car like the tC to make it happen, but the potential's still there. If someone wants to put forth the time and effort to apply a dual exhaust setup to the tc, then so be it.

Your point about the 4 bangers haveing potential has nothing to do with dual exhaust.
Duals are only for looks.

Well this turbo system actually still has two catalytic converters, and all emissions devices are still installed. One of the cats have been replaced with a high flow cat. There are no check engine lights on, and the emissions output is very clean (I do have emissions testing equipment). This car would still pass emissions testing with no problems whatsoever.

The problem is I do not have carb exemption for it, so California people would be the ones who would have problems getting passed.

For some reason no matter how clean your emissions are in California, if you modified your car and don't have an exemption sticker you will fail. TO me this sounds like California has a good money raping scheme going really well out there! I feel sorry for all you California people, but that’s the kind of ____ that the government gets away with.

Any way if the demand for this kit is high enough I will pursue carb exemptions. SO there may be hope!

Duals are only for looks.

What are you, retarded? How could you not understand this?

The first guy was asking why you would do something like a dual exhaust to a little 4-banger. I said "look at cars like the evo, SRT-4, etc.". Because you display the mental capacity equivalent to that of a 7 year old, I will break it down for you. I was pointing out other "4-bangers" that have obviously been hooked-up, pumped-up pimped-out whatver you'd like to call it. Therefore, people DO in fact find it worthwhile to do extensive mods to "4-bangers". Look at the Civic, the Golf, the WRX, the Celica and the list goes on.. plenty of people find enough "potential" in these small 4-cylinder engine cars to put money into them to do mods; some even as extensive as a dual exhaust setup, which does give a nice power gain. It's not altogether a pointless mod (yet another stupid point made by you). Therefore, to recap it yet again for you, I was pointing out why "you would do something like that to a little 4-banger like the tC". I don't know how to be any more blunt. I've already wasted enough time replying to this ridiculous post and some idiot who likes to act tough on the internet, and I think I've now had enough. Have a nice day.

It was, lol. But that's okay.. let that person shine like the moron he/she is.

Well if that was the point that your were making it wasnt that great.

Ive never seen anyone put duals on something as nice/fast as a modded Evo, STi and most people with SRT-4's only get duals so they dont have to fill the 2nd tip cutout. Also mainly because all the exhaust systems out are dual tiped.
Believe me, all the people I hang out with have SRT-4's and Evo's. NO ONE that I know puts duals on an Evo. There not retarded.

If someone wants to put forth the time and effort to apply a dual exhaust setup to the tc, then so be it.

This car is first and foremost a test bed for products that I am going to offer to you guys, secondly I use it as my daily driver because most of these parts will be on daily driven vehicles, lastly its a show car.
As far as my parts go, i won't develop a part unless it enhances the performance of the vehicle in some way and still be useable on a street car. This dual exhaust IS a benefit to a turbo tC. The less backpressure (on a turbo system) the more efficient the system will be. Going from 3" to dual 3" is less restrictive than a straight 3", hell i am pondering actually offering a 3.5" system going to dual 3" this would be even better. NOT to mention that the dual exhaust looks damn good on the tC, this you guys can't deny. I modeled it after the Japanese dual exhaust system that they offer for the Turbo MR2.

Well since this car has been turbo, I have raced all of these vehiceles you guys speak about so highly. The STI was raced on the way home from HIN. I raced him three times and killed him three times. I think he just couldn't believe he was being beat by a tC, the only explanation y he kept racing me. I also raced a modded EVO on the way home from the Moroso car show, He was giving me problems but i was still in his back. He was so surprised i was keeping up with him, that he actually slowed down and told me he couldn't believe it, and that he thought it was just a show car. The SRT-4 was right next to me but i was still creaping slowly ahead of him.

All three of these races were done with the stock tC exhaust system and at 7-8psi of boost pressure, all these cars run around 12-15 psi of boost stock to give you an idea. Now that i have the 3" exhaust system, it is much faster. This Turbo system will be offered at 10psi of boost, so those super compacts will have real problems with any tC running this turbo system. NOT to mention the price of a new tC, the 3" exhaust system, and the turbo system will still cost less than an EVO, and look better doing it.

You say you were up against an sti, an evo, and an srt4? How fast were you actually going? I thought the tC could only go like 127 before the limiter kicks in. I am pretty sure theother cars mentioned can go faster... Was it like a drag race where you go down the highway and try to go as fast as possible? Or, was it involving turns where you had to slow down and then speed up and then slow down.... I raced an eclipse last night on 195 south of Boston, heading towards RI. We were neck and neck until my limiter kicked in. My tach could go more too, but it just wouldn't go. It must have been an eclipse gt too, but I couldn't tell. It was the newest body style though.

alrite so every one talks about what's rice or whatever, and granted some stuff is "ghetto". But today I saw what I consider the most "rice" thing ever!!!!
picture it: a tercel (not sure on the year, the round body style), yellowyellow (not lambo), the too big wing and DUAL EXHAUST :o I decided to post this in this forum 'cause some are talking about why it's stupid for a tC to have dual exhaust, well if a tercel can--I think anyone can.

I so wish I had a camera.
BTW, yes I know this tC, is a turbo so the dual serves a purpose.

Does it? Real world turbo SAAB '03 95 AERO 2.3L stock puts out 250HP - mono exaust, no mods.. Dual exuast sounds like an easy answer but realistically how much HP/torque gain can you realize by going that way? Or we are just talking "visual effects" here in which case I would recommend a fake cellular antenna for $10 instead...

Stefan_TC

12-28-2004, 07:00 PM

only[/i] an 4 banger

And SMASH is absolutely right. What about this American obsession with number of cylinders? Isn't the point about HP/torque and not engine displacement and even less number of cylinders? If I can get 250+ HP from a 4 cyliner 2-something engine why would I want to go V6? Where is the advantage? The whole moto sport scene in Europe is dominated by four-bangers on turbo putting out in excess of 500HPs!!!!

TURBO is THE most efficient way to increase power with a minimal increase in the weight of the powertrain and IMHO HP/weight ratio is the key to success...

I had a pleasure of driving two turbo SAABs: '97 9000 AERO and '03 95 AERO with 230 and 250HPs respectively (single turbo) and there were NOT that many cars on the road that could race me... Check the specs of both cars if you do not trust me. (www.saab.com)

Turbos give you more HPs but also a lot of USABLE torque (which is way more important than HPs) . Surprisingly both cars had single exaust and I have not heard about a mod with dual exaust, there is simply no need for that with 4 cylinder setup...

We are all driving a four banger that has an engine coming out of a economy sedan, we cannot expect much in terms of performance, but to dismiss all four cylinder cars is just plain ridiculous...

Just to make a point, take a look at the link below. It is a page about SAAB pro racer Per Eklund who drives a modified SAAB 93 turbo. Now, this car has the smaller of SAAB engines - 2.0L (SAAB makes two engines 2.0L and 2.3L which is a version of 2.0) and still his his car makes 750HPs/518lbs from 2.0 four cylinders... (STOCK ENGINE!!!) and 0-60 in 2.3 seconds!!! Do you still wish your car had two more cylinders????? Clink on the link and read it will make you feel better :)
http://www.saabnet.com/tsn/press/000704.html

Now, to make something clear. The reason I birng up SAABs is that I miss my ride a lot.... Unfortunately after my last accident it will be long before I spend 40+k on a new car :( I also miss SAABs because of their UNDERSTATEMENT design. They do not look fancy, do not look nearly as fast as they are...
Also, different mentality: on SAAB forums there is little talk about the rims or dash kits but a lot about getting more oomph out of already powerfull 4-banger engines... and improving suspension...

I was never a big fan of Japanese cars as they IMHO lack the soul of a real sport car. Euro highways are much better than in US or Japan and the speed at which you travel (and that's not only on the famous Autobahn) are much higher that on American highways, which forces EURO automakers to design cars around the driver and not the cupholder...

Also, Euro motor sport scene is different with more focus on rallys rather than driving cars in endless and pointless circles. Fortunately SCCA rallys become more and more popular in the US, too SCION is my first Japanese car and I think it has a potential due to change in approach or design philosophy... They do have character and the only thing they lack is decent power plant... Let's see where this goes...

SRT, amongs many others is purely a "show-off car". I am not denying it is fast but it seems that ground effects and looks were much higher on priority list than its performance....

Just keep in mind that on a sport car each additional unnecessary pound means lost seconds on the finish line...

Stefan_TC

01-02-2005, 08:58 AM

people keep saying rice this rice that...how the hell is it rice!?...i was under the impression that rice mainly refers to something thats is just way out of place like say a bench for a spoiler or maybe a fully kitted ride with spining hubcaps, amazingly hude decals that take over the paint, theres plenty more that could be considered rice, but this TC seems perfectly clean and tight, regardless of whether te exhaust is functional or not, it looks tight as if it almost came like that OEM....just my .02

That's actually very simple. If you are driving a Ferrari, a large wing does not look cheesy as we all know what to expect from that car. If that's Porsche 911 than it is also fine. It may look funny but the driver will definetely beat you when the light changes...
Now, if you put a wing or a dual exhaust or a carbon fiber hood or anything that even remotely hints at sportiness or high performance on a car that simply can't deliver - than this is pure rice. No substance, just claims.

Rice means fake "carbon fiber" overlays, fake scoops and rear wings that defy the laws of aerodynamics. Fake cellular antennas and big "I got 500HP" decals on Honda Civics are also rice.
Keep it real folks, do not you feel really stupid, with all these wings and promo decals, when you are beaten by a family sedan? (ACURA, LEXUS, MERCEDES, AUDI, SAAB, BMW, INFINITY etc.)

well forget having two separate mufflers....isn't anyone thinking of having dual tip outlets like in the first picture, just using one exhaust/ muffler? i've been thinking about doing that from the first minute of getting the car, all's needed is a dual outlet muffler, then just cut the left side of the body to fit the new tip...
then you don't have to worry about the dual exhaust on a 4 banger issue...

My Evo was extremely fast, and at the videos of the turbo tC, I can see the Evo would easily win if the roll starts below 80. The lack of traction just seems to be a huge issue right now. I think your next mod should be super sticky tires that get that power to the ground. That's the best investment you can make, and will help a lot more than you think.

Speedlimiter cut will get you an extra 5-10mph, seeing how you're near redline at 130 anyway.

Nice turbo kit though. I'll consider it along with the TRD blower, or a possible custom setup. Either way, I don't see a good driver in an Evo losing to that at lower starting speeds.

NOT to mention the price of a new tC, the 3" exhaust system, and the turbo system will still cost less than an EVO, and look better doing it.

You pointed out a very good topic. No I have not removed the speed cut. These races were all on the highway, but they were basically from approx. 40mph to 130mph drag races. Basically if I let you go first @ 40mph and I'm a couple cars ahead of you when I hit 130mph you pretty much lose. Or if i let you go @ 40 mph and you can't get in front of me by the time I hit 130 then thats pretty close. Yeah definately would lose in a top speed match against these cars.

I am working on this problem diligently, i should have a solution in about a week if all goes as planned. But even if you remove the speed cut, you will still have the problem of the rev limiter. At 130mph the RPM is about at 6000rpm, so theres not much more to go before the rpm cutoff. I am also trying to remedy this by maybe changing the gear ratios on the transmission.

Hey buddy, you seem to be pumping some extra dense BS here...
First you are racing SRT4 than it turns out that you had to strike a deal with each one of them them to end the race at 130.... Did the all agree?
And now you promise to make TC faster than EVO...

Seriously now, how many of these kids are you planning to take for few grands?

??? WOW, Can you read? You are sounding really ignorant. I specifically said in the same statement you quoted, I would lose in a top end match! I did say these were rolling drag races! Not to mention the fact that these were before the 3" exhaust and these were before i was running 10psi of boost. Where is the BS??

Next time read don't skim, so you get your facts straight.

Hey C'mon guy. I am from Brooklyn, I can sell you a nice little bridge but not vice versa. You claimed you raced EVO and SRT. There was nothing about any "rolling drag race". You only added that when someone pointed out the speed cutoff on TC at 127mph which makes racing any sport car impossible. And that's why I do not believe you in the first place you change your story as you see fit.
Just admit it. You did not race any of the cars you mentioned in your post.
I am going to put your story next to the now famous "muffler turbine", for the same exact reason: no verifiable dyno results....
I understand you have your fart cans to push but for Christ's sake keep it realistic, OK?
Hey man, I was riding shotgun when he raced the STi and the Evo, and I can attest to you that this story is no BS. "Just admit it", you failed reading in grade school.
And if you're saying that it's not possible to race an Evo or STI because the speed cut is at 127mph then you my freind are a fool... and remember reading is fundamental.

I won't believe that this exhaust produces any power gains until I see a dyno sheet.

Agreed. "It looks....." "It sounds....."
Wasted words in my opinion. What happened to performance? The very idea that is so lacking in the so-called "import scene."

Much less.

Yes, I could take the time to type out an intellectual post detailing the blatant idiocy of splitting a 4cyl. exhaust, but my method was quicker and garnered more attention. I'm a whore, what can I say. Also, dual exhausts on inline engines is one of my pet peeves.

it never ceases to amaze me how people can get so judgemental over other's mods. hey, i want a dual exhaust on my tC... not because i think it'll be better in power, but because i like the look. now, i don't particularly like the exhaust at the start of this thread, but i give the guy props for doing something different. why can't we appreciate the fact that he was willing to try something new?

the best ideas usually come out of a hundred crappy ones. anyone brave enough to try (and then post pics of it for people to be critical) gets my admiration..... even if i'm not thrilled with what they did.

"Clean" or not, it's useless rice, period.

So what if you think it looks good - two mufflers on a 4cyl. car is stupid. It's just more dead weight that does nothing for the car.

Splitting the exhaust on an inline engine is ricey as hell. To each their own, but to me it just says that the person is an ignorant retard.

I can see where you are going with the whole idea of larger exhaust for a turbo but I must agree that dual exhaust is a lot of usless deadweight. There is nothing a single exhaust can't do that can be accomplished with a dual. The turbos for the scion are simply too small (unless you spraying with larger turbo which you are not) due to a lack of engine power to spin bigger ones in any street usable range. Those smaller daily turbo setup are not going to take advantage of anything bigger then a single 3" downpipe, midpipe and exhaust.

Moral: This exhaust looks good but hurts performance unless it is titanium.

He can be original all he wants, but its wasted motion, splitting the air up. It just needs to go through one pipe and out the back, bigger piping not a split. Thats quite possibly the dumbest thing I've read on here, that we should let him be who he is...stop whining, we are just saying its not useful...and its ugly as hell too...period.

the "whiners" are people who insist on posting how this exhaust is a bunch of rice, as if any idea or mod which they don't like is just plain wrong.

credit should be given to anyone who dares to try something new. yah, maybe it doesn't work or maybe it isn't your taste. who the hell are YOU to decide what is and is not the "best" exhaust design? if you're so damn smart, then go work for toyota or magnaflow and design the best exhaust for all of us. prove it with a dyno and THEN you can have a holier-than-thou attitude.

you like a single tip exhaust, and on the tC that is possibly the optimal design. but maybe this dual exhaust is the basis for a radical engine mod. you don't know what other stuff is in the works for this car. so you really don't have any business posting such a nasty opinion. you don't like it, fine. if you don't think the split design is good (and in that we DO agree), then you can say so without being a jerk.

A dual exhuast on a NA car is amusing.
It' works for show but not for go.

If this were a turbo'd tC, Might be... didn't bother to read all 5 pages here, then it would be even worse.

If the car is Superchaged, then it can be effective, sort of.. But I would not run 2 mufflers.

Ever see a M3 Dinan Exhaust? It's dual... but one is blocked. Wonder why eh?

If the headers plit from 4-2 and there were 2 straight pipes 2 cats then 2 mufflers...

This is funny. I have not been on here for a while.

You guys can hate it or you guys can love it. The bottom line is that this exhaust system is lighter than stock, It puts out more HP than ANY exhaust system on the market today, and personally i think it looks the best doing it. This exhaust will be available, in full stainless steel, and will come out later in titanium. It will also be available in a single for you dual haters.

oh yeah and the car that is pictured, does 12.0 sec to the quarter, and is at the present time the QUICKEST tC in the WORLD!

But then again, that's with a stage 3 turbo.

Most people are talking about how an NA car would not benefit from dual exhaust... that would, true enough, have the most gain, but the gain will be had so far into the power band that's it's not worth having.

This is the highest output exhaust system on the market so far on an NA car. Most people would assume what you have stated, but it is just not the case with the tC. We have done, extensive dyno testing and have very good results, which by the way contradict your statement about the power band.

In all we have two turbocharged testers and two NA testers. All of which are driven on a daily basis.

We will show all our dyno figures and test results after we have completed our first production run. We do not want any duplication by other companies until we release these exhaust systems, so all our info must remain proprietary until release.

I was giving you the benefit of the doubt up until now...if you've done dyno results, post them . I don't buy this BS about how you'll release the dyno sheets after production, due to concerns over duplication. What a crock. How does posting a dyno sheets have *anything* to do with concerns over someone copying your exhaust design??? What, are they going to look at your dyno sheet and pictures of your product, and somehow reverse engineer that into a similar setup????

Edited: didnt know your car *was* the scionspeed turbo kit :)

Exactly what you said is correct, it IS possible to reverse engineer using dyno sheets and pictures of a product if you know what your doing.

There are alot of exhaust companies out there, and we are not taking that chance.

Benefit of the doubt?? What would I have to gain by BSing anybody?? Like I said before when the exhaust system is released you will see dyno sheets. I guess you will just have to wait and see, and when you see the full exhaust system and how its made I think you will understand why.

So what's taking so long? The prototype seems to work very well.

I'd personally liked to get my hands on one since I have a new turbo fund.

(not saying turbo necessitates the dual exhaust or vice versa, just that it makes more sense to me)

BTW, does it come in more than one size? I see that the current prototype is a 3" so I could see how the tuning of the other size pipes would take long.

JMS001, why don't you post a little list of all the information that has been released about this dual exhuast system? It'd make things easier as it's quite difficult to dig through all six pages.

Question though: wouldn't splitting the pipe just create more turbulence? I understand the use of two exhaust pipes starting from the header with a dual 6-2 on a v6 but since we have a 4-1 (important part being the '1') how would splitting the exhaust pipe help and not hurt? Not to mention the split would have two 3" pipes (i think) so there would be a total of 6" cavern space which would act as a little mini vortex area that would collect the gases before fresh exhaust gas expels them from that little bay and out of the two pipes.

That's my understanding in any case. I would appreciate it if someone clarified the advantages (not the disadvantages, I'm pretty familiar with a few of those) of a dual exhaust system.

matty-tC

05-29-2005, 03:25 PM

the supposed increase in hp over a standard single catback would be null because of the increase in weight. a good 2.5" full exhaust would be the best for up to 250hp (crank) n/a or turbo with 3" for turbo beyond that.

dual exhaust is really just a show car mod unless this is the first 4 banger ever to get gains from it LOL

kungpaosamuraiii

05-29-2005, 05:26 PM

Flow condusive mods build up on each other so if a dual exhaust does increase flow over a single system than it would be beneficial if there is an increase on the intake side.

matty-tC

05-29-2005, 06:52 PM

then why not run a 5" exhaust?

law of diminishing returns. plus NA needs some sort of backpressure. FI you would need zero backpressure, but you can get that with 3" single.

kungpaosamuraiii

05-30-2005, 01:16 AM

A 5" exhaust that gets results would be SEXY.

The point I made was that if there is enough intake than a proportional increase should be made on the exhaust end.

A jet engine's exhaust is bigger than 5" :wink:

It's a different kind of engine I know but it's still a combustion with oxygen being burned up with a fuel's bonds being broken and whatnot making waste products (in this case, the "waste" is propelling the vehicle) that are being shot off. Say, a ram jet will gulp up air, thus, the 24" exhaust :silly:

Sooooo, if we shove enough air through the intake than this dual exhaust will make sense. If we shove more air than we can make due with a 5" exhaust.

If we have a 300 psi turbocharger than we can have a 2' exhaust pipe.

Point being any size, any number of exhaust will make sense if there's enough intake (and consequently enough exhaust) to fill it out.

matty-tC

05-30-2005, 02:25 PM

no it won't make sense because it's an inline engine thats only 4 cylinders. if you put a single 3" exhaust with a turbo it will be plenty of flow.

dual exhaust on this engine doesn't make any less backpressure than a big single

kungpaosamuraiii

05-30-2005, 11:52 PM

I don't see why you're still arguing with me. There are still things I want to know about this exhaust myself.

As far as I know, the system is split in the rear section like on many cars that AREN'T 4 cylinders (the G35 for one splits only in the rear section and is also NA when you buy it.) The reason for this is the cat in the back. By the last cat, the exhaust will have flowed through three (including the last one) cats or mufflers and consequently will have lost much velocity.

This is crucial to the design of the dual exhaust system because in the first portion of it's trip, the exhaust gases will have retained enough velocity to force its way through the first cat and the center muffler but will cause more backpressure in the last cat. Making the two split here, again, as far as I know, is to allow the now slower moving gases to have a combined total of 14 square inches to shoot out of instead of the 7 square inches in a single 3" exhaust.

Basically, the idea is this: fast moving gases go down one pipe, slow moving gases have two pipes to go down, back pressure caused by slow gases is divided by two.

jayson, i love the dual set up, bye the way. and i want one. for people who haven't tuned, they don't realize that by allowing more air in at the front, you also have to let more gasses out at the end. obviously this can be done with or without dual pipes. but, dual pipes certainly say to others that you are letting out more gas and if i was behind your car, i'd want to know why you need to do that. i'd assume you need to let out more gasses because your car is boosted. obviously, since it is, you do, so it's kewl. mine isn't, but i still want the dual tails.
