2011-12 SHELBY GT500 CAT-BACKS
Upgrading the stock exhaust on your 2011-12 Shelby GT500 with an aftermarket cat-back system is the most effective way to get the performance sound that you're looking for, as well as seeing increases in power and torque. Cat-backs go one step beyond an axle-back kit by also including new over-the-axle pipes that flow slightly better than the stock ones.
