2011 Mustang GT Roush Axle Back Exhaust w/ Rear Valance (421155)

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.

The ROUSH 2011 Mustang Exhaust Kit with Square Tips and Rear Valance will enhance the appearance of your vehicle as well. The tips are made from high-quality 304 stainless steel and are finished with a special chrome flashing process. Conventional chrome plating is comprised of layers of bonded chemicals to achieve its shiny appearance, which are susceptible to cracking and flaking, particularly in hot conditions (such as near exhaust gases). However, the chrome flashing used for this exhaust is bonded micro-porously to the metal surface. As a result, the tips are invulnerable to the normal chrome cracking from localized damage and heat color change. 409 stainless steel is used for the mufflers and inlet pipes for increased durability. This kit is protected by a 3 year limited warranty.
