2005-2010 Mustang Roush Exhaust

Make your car growl with the ROUSH* ® Ford Mustang Extreme Performance Exhaust Kit. Not only does this kit generate a mean sound, it also increases the horsepower and torque of your vehicle. The increased power is generated due to the higher flow system as compared to a conventional 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 Exhaust Kit creates more sound outside your car, 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 vehicle. Generates deep off-road exhaust tone Increases horsepower and torque Increases fuel efficiency No in-vehicle exhaust drone Manufactured using CNC bending to create smooth mandrel bends (resulting in higher flow) Made from 2.5-inch diameter stainless steel tubing Includes 4-inch diameter tips made from polished 304 stainless steel Comes with OEM clamps that won't damage pipes when tightened and provide a leak-proof seal No welding or cutting required Fits 2005 - 2009 Mustang GTs and Shelby GT500s with the stock rear fascia Part #403936
