|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.
