Yesterday i installed Pypes Violator Mufflers, and after seeing some of the people bashing these, they have very little to no drone at all, i have an o/r h pipe and are not that loud but not quiet, id say if the stock mid pipe was on with the cats, it would prob sound stock.... but i will say this in the lower rpms, they almost have a tingy sound to them... im not complaining just something i noticed a bit...
