C7 Corvette Grand Sport CORSA 14776 NPP Axle-Back Exhaust

Upgrade your 2017–2019 C7 Corvette Grand Sport (Automatic) with the CORSA 14776 NPP axle-back exhaust system, engineered to retain full factory valve functionality while delivering a wide, controllable sound range with zero drone.

Constructed from premium 304 stainless steel, the CORSA 14776 features a straight-through, high-flow design paired with 4.5″ quad polished Pro-Series tips for a clean, aggressive OEM+ appearance. CORSA’s patented Reflective Sound Cancellation® (RSC®) technology targets unwanted frequencies, allowing aggressive tone under throttle without intrusive cabin resonance.

With the factory NPP valves retained, this system provides a noticeable sound difference between driving modes — refined and controlled during cruising, and authoritative under heavy acceleration — all while maintaining daily drivability.
