Unleash your Mustang and let the 5.0L V8 Coyote engine howl with this Roush axle-back. The open-chamber design refines the sound of the engine without restricting flow, giving you the best of both sound and performance. 

Deep and powerful sound. Fitting the 2011-2014 Mustang GT and the 2011-2012 GT500, this exhaust will accent the exhaust of these cars and deliver an incredible sound. Menacing from the factory and known for their excellent performance, give your Ford the sound to match.

Bolt-on upgrade. These mufflers are a bolt-on upgrade for your Mustang and can be installed at home in the driveway or garage. An afternoon of wrenching will give you an excellent sound and put a smile on your face with every cold start.
