Best cat back exhaust system
Best performance...would have to be the original SLP loudmouth, and close second...probably GMMG. With you stock exhaust manifolds and the SLP y-pipe, the Loudmouth will sound great and flows the best. It has the straightest of the straight through designs. It is affordable too.

ya i doubt you will see any bigger performance gains with any one company over the next. until the manifolds get changed out catbacks are mostly gonna get you sound. as far as that goes the original slp loudmouth I sounds pretty sick IMO.
