so if im boosted at 7 psi, how big of an exhaust should do? cuz our stock ones are tinnnyyy. i was leaning towards a 2.5inch magnaflow catback, but i dunno, i need something as quiet and stock looking as possible. cops are **** about modded cars here, and ill get pulled with a loud exhaust in no time. any suggestions?

Apexi WS2. If necessary get the silencer.

what size is your downpipe? are you still running the stock downpipe and cat? any restrictive bends in the dp other than directly off the turbo? i think each of those items will be more restrictive that whatever exhaust you choose. I'm boosted at 5 psi and running 2 1/2 dp that narrows to accomodate the 2 1/4 piping of the magnaflow cat-back. no cat (aint GA registration grand?). the magnaflow is great but the canister is rather large. i've drug it out of a driveway more than once...
