Product Description

Make your presence known with the ROUSH® 2005-2009 Ford Mustang Extreme Performance Exhaust Kit. Not only does this kit generate a mean sound, it also increases the horsepower and torque of your 2005-2009. The increased power is generated due to the higher flow system as compared to a conventional Mustang exhaust system. Yet another benefit of this high flow system is that it improves fuel efficiency, as the engine runs into less air resistance to do its work. Though the ROUSH Extreme Performance Mustang Exhaust Kit creates more sound outside your Mustang, it doesn't create the typical off-road exhaust drone inside. This is made possible because sound is more effectively directed backward through the exhaust system and out through the rear of the Mustang. This 2005-2009 Roush Mustang Extreme Performance Exhaust kit comes complete with installation instructions and are ready to bolt on your car.
