Roush 2005-09 Mustang V8 Extreme Catback Exhaust Kit

The Roush Ford Mustang Exhaust Extreme Performance Kit gives your 2005-2009 Mustang GT that rumble sound letting others 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
