Corsa 3.0" Valveless Cat-Back Exhaust with 4.5" Polished Pro-Series Tips (21108) - 2020-2026 Corvette C8
Turn up the sound of your C8 Corvette with the Corsa Performance 3.0-inch Valveless Cat-Back Exhaust System. Designed for 2020-2026 Chevrolet Corvette C8 Coupe and Convertible/HTC models, this muffler-only Cat-Back system works with Corvettes equipped with or without the factory NPP exhaust system and delivers the loud, aggressive character enthusiasts want while maintaining Corsa's signature drone-free cruising experience.
This system eliminates the exhaust valves entirely for a simpler, pure-performance configuration that is especially well suited for heavily modified C8 Corvettes. Corsa's RSC® (Reflective Sound Cancellation) technology and straight-through muffler design deliver an aggressive exhaust note under throttle while controlling unwanted cabin drone at cruising speeds. Included valve simulators eliminate the factory NPP valves where applicable, helping prevent check engine lights without requiring a valve relearn procedure.

Valveless Performance Design
Unlike a valved exhaust system that changes sound based on valve position, the Corsa 21108 eliminates the exhaust valves for a consistently aggressive performance sound. The simpler valveless configuration reduces system complexity while delivering the louder exhaust character desired by drivers who prioritize sound and performance.
Corsa RSC® No-Drone Technology
Louder exhaust does not have to mean constant cabin resonance. Corsa incorporates its RSC® (Reflective Sound Cancellation) technology into the straight-through mufflers to target undesirable frequencies that create interior drone. The result is an aggressive exhaust note under acceleration combined with a comfortable, drone-free cabin during cruising.
Valve Simulators Included
For C8 Corvettes originally equipped with the factory NPP exhaust, removing the factory valves can introduce additional electronic complications. Corsa includes valve simulators with this system to eliminate the factory NPP valves where applicable while preventing associated check engine lights. No valve relearn sequence is required, helping reduce installation complexity.
3.0-Inch Cat-Back Exhaust
The system features a 3.0-inch Cat-Back configuration engineered for the C8 Corvette's 6.2L V8. Its straight-through performance design provides the aggressive exhaust character desired for stock and modified applications while retaining the refinement of Corsa's no-drone technology at cruising speeds.
4.5-Inch Polished Pro-Series Tips
The 21108 configuration is finished with quad 4.5-inch polished Pro-Series exhaust tips. Their dual-wall, slash-cut construction gives the rear of the C8 Corvette a clean performance appearance that complements the factory exhaust openings.
