C7 Corvette Grand Sport CORSA 14776BLK NPP Exhaust – Automatic
Upgrade your 2017–2019 C7 Corvette Grand Sport (Automatic) with the CORSA 14776BLK axle-back exhaust system, engineered specifically for vehicles equipped with the factory NPP active exhaust option. This system preserves factory valve control while delivering CORSA’s signature drone-free performance sound.
Constructed from premium 304 stainless steel, the 14776BLK features a straight-through, high-flow design and 4.5" quad black Pro-Series tips for an aggressive, factory-plus appearance. CORSA’s patented Reflective Sound Cancellation® (RSC®) technology eliminates unwanted cabin drone, allowing the exhaust to remain civil during cruising and aggressive under throttle.
With NPP active valves retained, the exhaust automatically adjusts volume based on drive mode: subdued and refined in touring mode, and bold and authoritative when the valves open.
