Corsa 3" Polished Stainless Steel Xtreme Axle-Back Exhaust System for all 2011, 2012, 2013 and 2014 GT Mustangs and all 2012-2013 Boss 302 Mustangs.

The addition of a Corsa axle-back exhaust system will boost horsepower and make a serious improvement in the sound department. Straight through mufflers are nonrestrictive to maximize air flow, improving both performance and fuel economy. A 153 percent increase in flow over the factory axle-back greatly improves flow and sound. Gains of 7 horsepower and 4 torque have been seen with the 5.0L engine. Corsa's Sport system features a dual rear exit 3" axle-back with 4" brightly polished Pro Series exhaust tips which fit the GT and Boss 302. Only the finest 304 stainless steel is used to construct Corsa's high performance exhaust systems. High quality metal ensures the look and sound of your exhaust won't change over the life of your vehicle. The extraordinarily durable exhaust sheds 18 pounds from the stock axle-back. The Corsa axle-back is 50-state emissions legal. Quickly install Corsa's axle-back with easy bolt-on installation. All hardware and detailed, full-color instructions are included. Proudly designed, engineered and manufactured in Berea, Ohio.

Corsa's exhaust systems are equipped with patented Reflective Sound Cancellation Technology. This technology was designed for an aggressive sound under acceleration and a drone-free experience during cruising. Every Corsa system is specifically designed for each application. Acoustic tuning refines and enhances the unique aggressive voice of your vehicle. Patented RSC technology cancels frequencies that cause unwanted cabin drone. These unwanted, low frequency sound waves are diverted through specifically designed channels and are reversed 180&deg. An innovative straight-through design maximizes engine performance by reducing back pressure and increasing engine efficiency.

If you want the most aggressive sound level available, the Xtreme will fit the bill. The Corsa Xtreme Axle-Back is the loudest exhaust offered by Corsa. Xtreme exhaust adds a deep growl at idle and becomes bold during acceleration. At high RPMs, your Mustang will absolutely scream. All this is achieved while maintaining zero drone at cruising speeds. Maintaining zero drone at cruising speed is what separates Corsa from it's competitors. Corsa offers the loudest exhaust note available while using patented technology to control the volume during different driving.
