So I installed the Roush Stage 2 Supercharger with Brenspeed tune on my 2013 GT. I ran for a few weeks on my GT 500 Exhaust, but wanted a little more aggressive sound. A buddy of mine had an unused set of Roush Axle-Back's and we installed them this past Saturday. OMG....love the sound but it is really, really loud. Anyone have suggestions on an alternative axle-back exhaust? The GT 500's are a little too tame and the Roush a little too extreme. Any suggestions appreciated.

 

Solo Performance Catback. You can get single or quad tips (I'm running) and it's just a great "in between" loudness exhaust. Mid muffler too, so it has that old school Mustang sound, that I feel is lacking in the axleback designs....

Before you change, try deleting the resonators. I have the GT500 quads, which are similar, and have the Lethal over axle pipes. They get rid of the resonators and straighten out the pipes. You could also have an exhaust shop weld in some straight pipe in place of the resonators, about 50 bucks. I think it sounds awesome with my supercharger. A little popping on decel, but for the most part, it sounds like I have a big block.
