ZZP fanboys will say otherwise, but everyone who's been here for long enough knows the GMPP SPORT is the bees knees

Haha I wonder why no one has gone out of their way to help you out after you try to **** talk the BEST sounding catback made for the SS/SC, performance is almost a non factor... there's a thread from JohhnyB from WAY back that has the dyno of before and after.

The dyno thread with the gmpp exhuast was skewed a bit because JonnyB did not dyno on the same day when he went from stock exhaust to gmpp. So the 12hp he gained is not accurate.
It def provides a bump in power though, because the inlet of the stock resonator is only 2 1/16", and the factory muffler is not a straight through design.
