The Corsa Sport Cat-Back Exhaust System (Black) is engineered to wake up your vehicle with a dynamic exhaust tone and performance upgrade—without compromising comfort.

Thanks to CORSA’s Patented RSC® (Reflective Sound Cancellation) Technology, this system delivers a +12 dB increase over stock under acceleration while eliminating the dreaded drone at highway speeds. The result is a sporty, aggressive exhaust note when you want it—and silence when you don’t.

Constructed from high-grade 304L stainless steel, the 2.5” cat-back system features a straight-through, non-restrictive design for maximum flow, adding horsepower and torque. You'll also enjoy a 13-pound weight savings over the stock exhaust, giving your vehicle better throttle response and slightly improved fuel economy.
