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. The result is an aggressive sound that is unique to ROUSH, increased longevity, 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. Not only does this system sound awesome, it looks great as well! The round tips are made from high-quality 304 stainless steel and are finished with a chrome flashing process, and are embossed with the ROUSH logo on the end. The exhaust kit mounts to the factory mounting points, and includes all necessary hardware. This makes for easy installation to get you back on the road in no time. The mufflers and inlet pipe are made from 409 stainless steel for increased durability.
