C7 Corvette Grand Sport CORSA Xtreme 14762BLK (Black Tips)
Upgrade your C7 Corvette Grand Sport with the CORSA Xtreme 14762BLK exhaust for a sharper, more aggressive tone without the annoying interior resonance that kills highway comfort. This system is built specifically for 2017–2019 Grand Sport models with automatic transmission and finishes the rear with quad 4.5-inch black Pro-Series tips for a stealth performance look.
Like all CORSA systems, 14762BLK is engineered around RSC® (Reflective Sound Cancellation) technology. Instead of packing material that can burn out over time, CORSA acoustically tunes the system to target drone frequencies while preserving the “on-throttle” bite people want from an Xtreme setup. The result is a car that sounds aggressive when you get into it, but stays controlled during steady cruising.
Valve / NPP clarity (important): This is a non-NPP exhaust. If your Grand Sport was originally equipped with factory NPP, this system can still fit, but it will not retain the factory dual-mode valve function — you’ll be running a consistent exhaust tone and the factory valve actuators/valves will be disconnected and secured.
