CORSA Perf NPP Cat-Back 4.5in Black PVD Tips | Chevrolet Corvette C8 (20-26) (21103BLK-1)

The CORSA Performance NPP-only C8 cat-back exhaust is designed to give drivers control over their Corvette’s sound while delivering a more aggressive V8 character. Fully functional CORSA cast NPP valves integrate with the factory C8 actuators, preserving control of the exhaust sound profile. The system is 9 decibels louder and 1 decibel quieter than the stock system, depending on operating conditions, and uses CORSA’s proprietary RSC technology for a drone-free driving experience. Under heavy acceleration, it lets the 6.2L LT2 produce aggressive exhaust notes. This configuration features 4.5-inch Pro-Series tips with a Black PVD finish. An AFM valve simulator is included to help prevent an AFM check-engine light.

Designed for 2020–2026 Chevrolet Corvette C8 models equipped with the factory NPP exhaust and 6.2L LT2 V8, this cat-back system retains compatibility with the stock NPP actuators through its functional valves. The AFM valve is replaced by a simulator engineered specifically to prevent an AFM check-engine light. The source does not specify installation steps or additional fitment requirements. With adjustable sound characteristics, RSC drone-reduction technology, and aggressive exhaust tone under acceleration, the system is suited to drivers who want to maintain control of their Corvette’s sound profile. CORSA identifies it as ideal for aggressive drivers who plan to drive primarily in Track Mode.
