A line of premium exhaust systems is now available from CORSA Performance Exhausts for the 2011 Ford Mustang, both V8 5.0L and V6 3.7L engines. The CORSA Mustang axle-back exhaust systems feature a dual rear exit design with 4-inch Pro-Series tips etched with the CORSA logo. Engineered using the company's patented Reflective Sound Cancellation (RSC) technology, the new exhaust systems deliver a muscular sound with no unwanted interior drone. CORSA offers two distinct sound levels for the 2011 Mustang GT exhausts: the Sport Exhaust System (part #14316) is bold and robust on the throttle while the Xtreme Exhaust System (part #14317) produces a louder, more aggressive note. CORSA's Mustang GT 5.0L systems are 18 lbs. lighter than stock and deliver a 153% increase in flow, which results in a performance gain of 7 HP and 4 lb.-ft. of torque. The optional XO-Pipe from Corsa (part #14318) adds an additional 3 horsepower to both the Sport and Xtreme systems. In addition to the GT 5.0L exhaust, CORSA offers performance exhaust systems for the V6 Mustang, 4.6L 3-Valve and GT500. Complete installation hardware and instructions are included with the 2011 Mustang exhaust systems and a Limited Lifetime Warranty protects the exhaust for the entire life of the vehicle. The exhaust systems are crafted in the United States from premium stainless steel, and all tips are double wall, highly polished stainless steel laser etched with the CORSA logo.
