I'm looking to replace my Magnaflow street axle backs with the 2005-10 Roush Extreme axle back/muffler delete resonators.. Anyhow I'd like to find out if anyone would happen to know how they sound on a 05-10 3V GT, as I'm looking for that deep, throaty aggressive sound, but don't want the annoying cabin drone while cruising at highway speeds.. I'll also be pairing them with the "OEM" catted H-pipe and stock exhaust manifolds..
In the meantime, here's a link and image for the 05-10 Roush Extremes..
