This CORSA 3.0in cat-back exhaust is for the 2020-2024 Chevrolet Corvette C8 Stingray (coupe and convertible) with the factory NPP performance exhaust. CORSA NPP valves work with the stock actuators so the driver keeps control of the sound across the drive modes, while the AFM valves are deleted. It exits at the rear through quad 4.5in Pro-Series dual wall slash cut tips in Black PVD, saves 16 lb over stock and is rated at up to 18 hp and 16 lb-ft for the system line. In 4-cylinder mode it may show light resonance.
