Does anyone know if there are mufflers out there (borla, corsa, magnaflow) that will fit 05 gto without cutting or welding???

MagnaFlow's catback should be out very soon.

On the dyno, the 05 mufflers lost 2 rwhp over open exhaust. If you want more noise, just change the muffler, any shop can do it.
