C7 Corvette Grand Sport CORSA Sport Axle-Back Exhaust 14764 (2017–2019)
Upgrade your C7 Corvette Grand Sport (2017–2019) with the CORSA Sport axle-back exhaust system, part number 14764. This system is engineered specifically for automatic-transmission Grand Sport models, delivering a sharper, more athletic exhaust tone while preserving everyday drivability.
Constructed from premium 304 stainless steel, the CORSA Sport 14764 uses a straight-through, high-flow design paired with quad 4.5-inch polished Pro-Series exhaust tips to complement the Grand Sport’s wider rear track and aggressive factory styling.
CORSA’s patented Reflective Sound Cancellation® (RSC®) technology is acoustically tuned to eliminate interior drone at highway speeds, allowing the exhaust to stay civil during cruising while delivering a stronger, more defined tone under throttle.
Why Grand Sport owners choose the CORSA Sport 14764
- Sport sound profile: aggressive and refined without being overpowering
- RSC® no-drone technology: engineered specifically for the Grand Sport cabin
- 304 stainless steel: corrosion-resistant and built for long-term use

Fitment & important exhaust notes
- Fits: C7 Corvette Grand Sport (2017, 2018, 2019)
- Transmission: Automatic only
- Factory exhaust: Compatible with vehicles originally equipped with NPP or non-NPP exhaust
- Important: This is a non-NPP axle-back system. Vehicles originally equipped with NPP will no longer retain selectable exhaust modes, and factory valves/actuators must be handled per the installer’s preferred solution.
