Corsa Black Sport Cat Back Exhaust Subaru STI 2011-2014 / WRX 2008-2014 Sedan Manual
Corsa Sport exhaust systems employ a straight-through, non-restrictive design. They're coupled with their patented reflective sound cancellation science to tune out annoying low frequencies that cause droning and leave you with a crisp, clean sound. This cutting-edge innovation also reduces backpressure, allowing your engine to produce more horsepower and torque. The robust, aggressive-sounding Corsa Sport exhaust systems are manufactured from premium stainless steel, with mandrel bends and handcrafted tips polished to a gleaming brightness to enhance your ride's appearance. Developed to fit right every time, Corsa exhausts go on fast--no cutting or welding is necessary. Corsa Sport exhaust systems are bold when you want them to be, quiet when you need them to be, and proudly made in the USA!
