Your cart is empty.The ROUSH Axle-Back Mustang Exhaust Kit with Round Tips, designed to fit the 2011-2014 Mustang GT & 2011-2012 Mustang GT500, is an innovative exhaust system from ROUSH that features an open-chambered designed muffler (as opposed to conventional fiberglass-packing). The result is an aggressive sound that is unique to ROUSH, increased longevity (with no fiberglass packing), and increased horsepower & with additional airflow. Another added benefit of this system is the lack of the in-cockpit boom normally found with performance exhaust systems at cruising speeds.

This is absolutely hands down the best sounding Axle-Back exhaust system available for a Mustang. Then again, it’s Roush!! It is what I would expect.

Seems to be a lot louder than in their video. Look good, and the Shelby is putting out 620 Hp, without much effort.
