So I recently got the APR DP and HFC with the stage 2 reflash.
From reading on the forums it seems that most of the power I can get from the exhaust/DP is from the DP and reflash and that the Catback would be minimal gains but better sound.
I was wondering if I could just get aftermarket mufflers to get a better, deeper sound while keeping between the CC and the muffler the same.
If so what kind of mufflers would work? My car is a 2009 A4 Avant (Dual Exit).
