Corsa 3.0" Valveless Cat-Back Exhaust with 4.5" Polished Carbon Fiber Tips (21108CF) - 2020-2026 Corvette C8
Give your C8 Corvette the aggressive exhaust note it deserves with the Corsa Performance 3.0-inch Valveless Cat-Back Exhaust System. Designed for 2020-2026 Chevrolet Corvette C8 Coupe and Convertible/HTC models, the 21108CF works with Corvettes equipped with or without the factory NPP exhaust system. This muffler-only Cat-Back combines a loud, performance-focused exhaust note with Corsa's signature no-drone technology and premium polished carbon fiber tips.
Built for drivers who want pure exhaust sound without the complexity of an active valve system, this Corsa Cat-Back eliminates the exhaust valves entirely. The straight-through muffler design and Corsa RSC® (Reflective Sound Cancellation) technology deliver an aggressive exhaust note under acceleration while maintaining a drone-free cabin during cruising. This combination makes the system especially appealing for heavily modified C8 Corvettes where sound, simplicity, and performance are priorities.

Valveless Performance Design
The Corsa 21108CF eliminates the exhaust valves for a simpler configuration and consistently aggressive exhaust sound. With no active valves restricting the sound experience, this system brings out the character of the C8 Corvette's 6.2L V8 while reducing the cost and complexity associated with a valved Cat-Back system.
Corsa RSC® No-Drone Technology
More exhaust volume does not have to mean uncomfortable cabin resonance. Corsa's RSC® (Reflective Sound Cancellation) technology is engineered to target the undesirable frequencies responsible for interior drone. Combined with the system's straight-through mufflers, RSC® technology provides an aggressive exhaust note under throttle while maintaining a comfortable, drone-free cabin during cruising.
Valve Simulators Included
C8 Corvettes equipped with the factory NPP exhaust use electronically controlled exhaust valves. Because the Corsa 21108CF is a valveless system, Corsa includes valve simulators to eliminate the factory NPP valves where applicable while helping prevent associated check engine lights. No valve relearn sequence is required, reducing both the cost and complexity of installation.
3.0-Inch Cat-Back Exhaust
The 3.0-inch Cat-Back configuration is engineered around the C8 Corvette's 6.2L V8. Its straight-through muffler design delivers the aggressive exhaust character enthusiasts want while Corsa's acoustic engineering maintains refinement during steady-speed driving. The valveless layout also makes this system an excellent option for C8 owners with extensive performance modifications.
4.5-Inch Polished Carbon Fiber Tips
The 21108CF configuration is finished with quad 4.5-inch flat-cut carbon fiber exhaust tips featuring polished detailing. The carbon fiber construction gives the rear of the C8 Corvette a premium motorsport-inspired appearance, while the polished finish provides a clean contrast against the carbon fiber for a distinctive performance look.
