Corsa Sport / 3.0 in Cat-Back SSE 4.0 in Twin Tips | 11-13 Silverado Sierra 2500 6.0L 144WB cor14792

The CORSA Performance 3.0" Sport Cat-Back Exhaust System was designed to elevate the sound and performance of the 2011–2014 Silverado and Sierra 2500 6.0L V8. Built from premium T304 stainless steel, it provided superior durability, corrosion resistance, and a bold exhaust tone that defined CORSA’s signature performance sound.

Featuring a Single Side Exit (SSE) with Twin 4.0" Polished Pro-Series Tips, this system combined aggressive styling with advanced acoustic engineering. CORSA’s patented Reflective Sound Cancellation® (RSC®) Technology eliminated interior drone while preserving a deep, refined growl during acceleration — ideal for enthusiasts seeking power and comfort in one package.

Though this system is no longer in production, it remains a benchmark for sound quality, fitment precision, and build excellence.
