Just curious as to what everyone has as far as exhausts with their supercharged or turbo set up? Also has anyone had cel problems with your set up? Anyone using a hi flow cat? Test pipe? Stock cat? Stock exhaust?

 

Custom true 3" exhaust from the turbo back. Vibrant 3" Ultra Quiet Resonator. Vibrant 3" Muffler (straight through).

Seems to be performing wonderfully.

 

Stock AP2 exhaust, 70mm Berk HFC, stock headers. AP1 vortech V2 @ 10 psi.

 

3in piping, vibrant res, dual magnaflows

 

Really? Stock exhaust? How is it doing? I should of mentioned I'll be using my invidia q300 with the stock cat, but I was considering my ap2 exhaust and berk test pipe.

 

T1R 70mm single. It's a loud exhaust but I get compliments about how it sounds on the outside. I'm not sure how it sounds on the outside b/c I don't let anyone else drive my car.

 

I don't have the Turbo on yet but I will be running the Berk headerback 3"exhaust with the gtx3076r trackforged kit.

 

Stock exhaust here with S/C and test pipe at 10psi. I'll be running the same exhaust in a few weeks when getting retuned on E85 at ~18psi.

 

Nice! How much different is running your stock exhaust compared to an aftermarket?

 

Originally had the HKS Hi-Power dual exhaust mated with the Berk Technologies 63mm test pipe, but went back to the stock (ap2) exhaust and absolutely love it! Wish I had switched back to the stock cat-back sooner.

SOS 6 psi.
