Shopper Award

The Ford Mustang Exhaust Extreme Performance Kit gives your Mustang that rumble sound letting other's know you mean business while increasing 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. Fits 2005-2009 Ford Mustang GT|GT500. Though this particular exhaust for the Ford Mustang 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.

The exhaust system is manufactured using a CNC bender to create smooth mandrel bends. This process maintains a consistent inside diameter through the bended area and allows for a significant increase in flow over stock/serrated-bent pipes. This Ford Mustang exhaust kit is made from high-quality 2.5-inch diameter stainless steel tubing and has 4-inch diameter tips made from polished 304 stainless steel and embossed with the ROUSH logo. The system comes with OEM stainless steel exhaust clamps that provide a leak proof seal and won't smash or crush the pipes when tightened. The ROUSH Resonator Off-Road Exhaust Kit fits 2005 - 2009 Mustang GTs and GT500s with factory rear fascia.
