GMG GT3 Exhaust!!
 

I posted on 6speed as well...


I was at GMG this weekend and this thing sounds soooo mean in person. The kit just replaces the center muffler.

Any info on Dyno effects, if any, plus or negative?....sounds like my old 996 Fabspeed bypass kit

Just what's on their site...BTW, no affliation.
