2011-12 MUSTANG GT/BOSS 302 CAT-BACKS
Upgrading the stock exhaust on your 2011-12 Mustang GT or BOSS 302 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. Browse our selection of top-quality Mustang cat-back systems below.
