The CORSA 21108BLK Pro-Series cat-back exhaust gives the C8 Corvette a louder, more aggressive exhaust note while cutting nearly 19 pounds from the factory exhaust system. This valveless 3.0 inch system uses Reflective Sound Cancellation to eliminate drone at cruise, so the cabin stays comfortable while the exhaust note stays intoxicating under throttle. Twin 4.5 inch black PVD Pro-Series tips finish off the look, and valve simulators eliminate the factory NPP valve without triggering a check engine light or requiring a valve relearn.

Frequently Asked Questions
Will this CORSA product fit my 2020-2026 Chevrolet Corvette?
That vehicle range is listed, but confirm the exact manufacturer part number, trim, cab or body style, factory exhaust or intake configuration, and every application note before ordering.
How should I choose the correct CORSA exhaust configuration?
Compare sound level, pipe diameter, exit location, tip finish, factory valve or active-exhaust requirements, cab and bed or body configuration, and the exact part number.
Does this CORSA exhaust require professional installation?
Vehicle-specific systems are generally bolt-on when the exact application matches. Universal components can require cutting and welding. Professional installation helps ensure alignment, clearance, sealing, and correct clamp torque.
Installation Instructions
Follow CORSA and vehicle service instructions. Support the vehicle safely, allow the exhaust to cool, verify all hangers and clearances, align the system before final tightening, check for leaks, and recheck clamp torque after the first heat cycle.
