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.

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

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.

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.....
