Draxas is going to release a new product... the High Flow S-pipe for the tC... can somebody explain what would be the benefits? :pray:

this is the web site... http://store.draxas.com/browse_products.asp?Cat=2&Sub=113

The factory S-Pipe is crush bent 2" tubing which is very restrictive and makes a bottle neck in the exhaust if you install the header. Which I believe it may be the S-Pipe making the exhaust sound raspy with a header.

i thought the tc stock exhaust was all mandral bent

well.. headers are known to make the car sound raspy...or "tinny" like a tin can.. raspy isnt the problem.. its its the rasp sounds like sh*t.... but the s-pipe im sure is VERY restrictive.....when i get my borla muffler im gonna have my guy run a straight pipe no cat..keep the stock resonator...and prop have him bend a new s pipe for me...i'll let you guys know how it sounds....

....one of my good friends has an SRT-4 with some decent mods and his car sounds SICK... the meanest car i have maybe ever heard..its like a V8 4 cylinder....crazy loud Blurbles and pops..and a mean growl..you would sh*t your pants...and his is a 2.4L...but its a turbo..no cat..borla exhaust....hmm

i'm pretty sure a biger s-pipe combined with a header, and exhaust will make it louder if anything, the restriction from the stock spipe would quite it down

130 bucks for just an s pipe seems like a lot for something that small...

i agree but it would definately be worth a 5-7hp gain.

true but from gains on their other products I don't see that happening...

(insert finger crossing smiley)

I would like to buy it when I get a header

im prollly gonna get it too for some hp gain

5-7 hp gain? wow!!! that's almost the same than an intake, and it costs the 1/2 of it

I think he was just guess its not be released...

You're not going to get 5-7hp from that thing. 1 if you're lucky. The stock one isn't THAT restrictive unless you're rockin a ton of boost.

if you want to do it right you have to take out all of the restrictions. from intake to header to all exhaust piping. with the s-pipe you are getting rid of the restrictions allowing max power. you are losing power with the stock one.

creative compacts will have one out very soon as well

Phillip will be picking his car Scion tC up tomorrow, with one of our high flow S-pipes installed. He has an appointment at the dyno facility for 1:30pm PST. This new dyno will be with our full exhaust system, high flow S-Pipe, and K&N CAI. We will take the gains that K&N publishes for their intake, and subtract that from our new dyno number, to get the gains of the S-Pipe.

I believe that we will see decent gains from the S-Pipe.. and those people who choose to install a header wil see even better gains, naturally. I honestly believe that the stock S-Pipe is the reason why people are only gaining around 7-8whp from a race header.

cant wait to see the #'s.

Is there anyway a dyno can be done without the K&N and with the stock airbox instead? It's common knowledge that just because an intake alone provides 6hp and a full exhaust alone provides 10hp doesn't mean the result together will be 16hp. I'm planning on getting the WeaponR SW intake and I'd just like to see the most accurate numbers for your setup, besides it might show more of a gain by itself instead of subtracting the K&N's numbers from the combo. Bigger numbers mean better marketing. :)

I will speak with Phillip today to see how much of a PITA it will be for him to dyno with the stock airbox installed first, then re-install the K&N. If it will only take him a few minutes to swap them out, then I dont see it being a problem.

Phillip expressed concern over how restrictive the stock airbox is. We think that because the stock airbox is so restrictive, the S-Pipe will not be able to work to its potential, or at least not as close to its potential as we would like.

The other reasoning we used, was that not many people are going to install JUST an exhaust. Most everyone will install both an Intake and Exhaust.. So, showing our Project tC with a CAI and our exhaust , in our opinion, is more realistic of what the general public will see on their own cars.

Similar argument can be made for testing a race header all by itself (stock intake and exhaust).. I dont know many people who will ever install a header without also having an intake and exhaust installed..... :)

That's true but the same can be said for a lot of things. The exhaust could produce different power on quite a few different mods. Alone your complete exhaust design could produce 15whp, then if you add the K&N, it might only increase 2-3 more. Now say at that point you subtract the 6whp the K&N produces alone, you've just under cut your exhaust to 12whp. From a marketing standpoint, the 15whp number is more appealling and a lot of people might not get the K&N CAI and could experience totally different numbers.

The example that comes to mind is the Alphawerks 60mm throttle body. They did a dyno with and without the TB in combo with I/H/E. The difference between the two dynos was 1HP and 1.2TQ. Now everyone's thinking "Damn that TB only produces 1HP, forget that POS", now if they dyno'd it by itself it might produce 4-5HP (or more) in a stock setup and might seem more worth it.

excellent points and that's really the way you should market.

This is all very nice but if you guys want a nice sounding exhaust and want it fast and that shows results get an apexi n1 n/a universal muffler go to super tuning and ask for koko have him make you the full exhaust kit using this muffler and you will gain some hp fast and easy and not to mention it sounds great. Well the only difference is that I got a forced induction but I can honestly say that ever since I got my exhaust done it sounds sooooo good and my car has way more torque on higher rpm's totally worth it and I know coco can make you the exhaust for about 150 to 2 bills just bring your muffler or get it from him he hooks it up. PM me for his information.

Is it koko or coco? I wouldn't want to insult the guy. j/k

The key here is you're running a turbo, I heard the Apexi N1's sound like wet farts if you're N/A. Is this the case?

the apexi N!'s for some reason sound way better with turbo's cuz with other wise it will sound very loud and like he said above like a wet fart.

hrm thats weird. the N1 sounds amazing on an na 95 supra and a 91 na 240sx.

hmmmm

the reason i said it sounded loud without turbo was cuz i knoe a couple of people that have gotten the apexi n1 setup on there tc n it was very loud high pitched but maybe it sounds better on some cars...i have heard this on my friends turbo tc though n it sounds amazing, its quite but still has a rumble to it

I noticed a little bit of a power loss in the lower RPMS from the megan header, does anyone know if this mod will clear up that problem?

doubt it, as I understand it, the reason that you loose the low end power is because of loss in back pressure. This mod should lower the backpressure even more possible making this problem worse. get the supercharger or turbo setup on your car and the problem should be solved. :P

To my understaning, I think its going to depend on whether or not the diameter of the new s-pipe allows for a greater velocity or volume of air-flow over the stock diameter. The wider diameter replacement s-pipe is more then likely less restrictive than stock and will allow for a greater volume of air to pass through, but if it does so at a loss of flow velocity over stock then you'll likely see a more pronounced loss down low w/ even further gains up top. However, if the air-flow velocity of the new s-pipe is greater then that of stock, then yes, it will make up for some of that loss and still provide nice gains across the entire powerband. However, this is all assuming your NA, because when you go FI, bigger is better, plain and simple. The maximum volume is what's is going to count then, since the turbo or super will be more then able to keep velocity up. Also, keep in mind, everything behind the s-pipe is going to be a factor, as well.

Hello,

I saw alot of posts here for a full exhaust and intake setup. For an FYI I wanted to post the dyno and the webpage for the soundclips and dyno videos...

DYNO: +24whp and +19lbs/tq (w/o resetting ECU)
-Alphawerks Throttle Body
-Alphawerks Short-Ram Intake
-Alphawerks Header
-Alphawerks Cat-back Exhaust

Is that w/ the stock s-pipe or does your exhaust or header come w/ a replacement s-pipe? I couldnt find that information on the Alphawerks' website. Impressive numbers regardless.

That is with the stock s-pipe. The factory s-pipe is pretty restriction free and so to get a good gain out of it we have to do a lot of testing. This is a warning to all those who just want to throw any pipe on there. There are two very difficult angles in that pipe. So beware of wasting $. But we are almost done with our S-pipe which should be ready next week.
