Agency Power created an exhaust system that portrays the right exhaust note without sacrificing power on the naturally aspirated motor. The 3 Inch stainless steel piping and dual muffler design gives the Mustang GT a true race quality sound without robbing the car of performance. Like all Agency Power exhausts, durability and look are just as important as power and sound. The dual exhaust is TIG welded and finished with a mirror polish that is enhanced by the 4 Inch round exhaust tips.
From the factory, the Mustang is mild and leaves you wanting more. With the Agency Power exhaust, your grip tightens and heart races as you fly through the RPM range. And if that wasn;t enough, a lift of the throttle unleashes a growl that lets everyone know, your car means business. Power gains of 10hp and 20tq to the wheels throughout the power curve is yet another reason you need to bolt on the Agency Power Race Tuned exhaust to your 2011 Mustang GT.
