Stop choking your 5.0 with a stock exhaust and enjoy more horsepower with a Magnaflow Competition Cat-Back. By reducing backpressure and giving your Mustang GT or GT500 a free-flowing exhaust, you'll see great power and torque gains. In fact, our 2011 Project car has this same system with the off-road x-pipe, and was dyno tested with a peak gain of 19 RWHP and 18 ft-lb of torque. Plus, you'll set the stage for future mods.

Give your 2011-2012 Mustang GT a deep, aggressive rumble that will make lesser cars clear a path at lights with a Magnaflow Competition Cat-Back. This premium quality exhaust features free-flowing, straight-through mufflers that increase power and give your GT or GT500 an unmistakable musclecar sound.

Each piece is made from 3" mandrel bent stainless steel tubing for long life and a perfect fit. The straight-through mufflers end with brightly polished 4" stainless tips that exit in the stock locations for impressive styling.
