The Ultimate Driver’s Exhaust System.
For the Corvette C8 exhaust we incorporated our latest technology (Corsa NPP valved sound control) and the most advanced RSC® No Drone Technology to give you complete control of the driving experience.

Exclusive CORSA cast valve assemblies were completely redesigned to meet the intense heat needs unique to the C8 Corvette. Valve assemblies mate seamlessly to stock actuator motors to maintain all C8 driving sound modes without throwing a Check Engine Light (CEL).

The CORSA NPP Exhaust is both louder (+9 decibels) and quieter (-1 decibel) than the stock system. Our C8 performance exhaust unleashes exhilarating exhaust notes from the 6.2L LT2 engine with the refined driving experience only a CORSA exhaust can provide.

INSTALLATION INFO

🗒️ Installation Instructions

CORSA recommends installation of exhaust be performed by a professional. Due to GM Factory tolerances some C8 exhaust systems will require GM valve relearn sequence (valves should be re-calibrated according to GM Document ID 5406413) to mitigate a check engine light. See Installation Instructions for more details.
