Give your car the sound it deserves with the ROUSH 2011 Mustang Exhaust Kit with Square Tips and Rear Valance. The innovative open-chambered design of the muffler in this kit doesn't have the fiberglass-packing found in conventional mufflers. The result is a unique sound that isn't held back, and also because of the lack of fiberglass packing, this kit has improved air flow and maximized power. The square tips of this kit fit nicely into the exhaust ports of the ROUSH 2010-2011 Mustang Rear Valance, which is also included in this kit.
Another feature of this system is the absence of an cruising speed in-cockpit boom, commonly found with aftermarket exhaust systems.
