Roush Mustang Axle Back Exhaust with Square Tips and Rear Valance (2011-2012 Mustang GT ; Boss 302)

*image is only a representation and may not be accurate
This ROUSH® Mustang Exhaust Kit is designed for the 5.0 L V8 2011-2012 and comes 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 end 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 2010-2012 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.

The tips are made from high-quality 304 stainless steel and are finished with a special chrome flashing process. 409 stainless steel is used for the mufflers and inlet pipes for increased durability. This kit is protected by a 3 year limited warranty.

This system installs quickly and easily. The exhaust uses the factory exhaust hanger mountings, which means that you don't have to make your own. This kit also includes OE-quality spherical clamps for an optimum fit. Because this is a cat-back exhaust system, it has no impact on emissions.

Customer Reviews

To make it simple this is what I was looking for. I wanted an exhaust that would dramatically change the look of the car, no in cockpit boom, no drone, quiet while cruising, and screamed at wide open throttle. This exhaust perfectly fit that quota. It has such a mean muscle car sound to it while not overdoing it. Don't worry its still got bark! Even my magnaflow and flowmaster friends were jealous. The shipping was fast and fantastic. Everything came boxed perfectly. Don't waste another minute this exhaust is the way to go!! (Posted on 12/11/14)
