I currently am running a custom cat back system with this cheap *** muffler... i was wondering if anyone has slapped on a stock wrx muffler on their cars? how does it sound? any performance gains? any input is welcome...thanks!!

 

It sounds VERY quiet, but you can gain a little power due to the larger piping.

 

that's what i want!....my exhaust now...it's nice and all but i'm getting tired of the loud *** noise during long road trips. I just wanna retain my performance but give up the sound. Plus i have a resonator so that'll tone it down even more. any sources for stock wrx exhausts in cali, preferably in the bay area please let me know...
