Initially i was thinking Roush, but then i had a change of heart and was thinking about Ford Racing Sport. Allot of people complain about drone with the Roush and it sounding a bit too high and ricey. After thinking about it for awhile i think i would like to do catback instead of axle back because some extra power would be nice. I was on American Muscle and all they have for the 2011 v6 catback exhausts are Magnaflow Sport, Magnaflow Competition and Pypes... all of which are not to my liking. Why dont they have the Borla Catbacks for the v6 on american muscle instead of only Borla Axlebacks? Maybe somebody knows a better site with more selection? Either way, what do you guys have? Are you happy with it? The guys that have catbacks... any noticeable gains you can feel? The guys that have axlebacks... is the sound that good that you dont care about additional gains?
