2027 Chevrolet Corvette Grand Sport Exhaust Systems
Now Available!
Note: These systems are not compatible with the center-exit exhaust option from factory. Center-Exit systems for the 2027+ C8 Corvette are in development.
The C8 Corvette Grand Sport has arrived and is equipped with an all-new 6.7L power plant from Chevrolet. The new small-block engine increases the power by 40 horsepower and 50 lb-ft of torque compared to the outgoing 6.2L.
Originally designed on the 6.2L engine, Borla has done extensive testing for fitment and sound of their C8 Corvette systems on the new engine. We have extended our coverage to the 6.7L LS6. Our exhaust systems come in two flavors: S-Type and ATAK. The S-Type gives a deep V8 rumble while the ATAK delivers an aggressive racing growl. Both sound levels are free from drone or resonance inside the cabin. Tip finishes include chrome, black chrome, and carbon fiber. Bolt on the best, bolt on a Borla.
System Features:
- Cat-Back Exhaust Systems
- S-Type and ATAK® Sound Level
- No-Drone
- Includes AFM and NPP Dual Mode Exhaust Valves
- Quad 4” Tips in Chrome, Black Chrome, or Carbon Fiber
- Patented SwitchFire® and Polyphonic Harmonizer Technology
