PRODUCT DETAILS ▾
The CORSA Performance 4-Valve NPP cat-back (part 21100) is a 3-inch valved exhaust for the 2020-2024 Chevrolet Corvette C8 Stingray with the factory NPP performance exhaust. It keeps both the NPP and AFM valve functions, so every factory drive and sound mode still works, and CORSA's RSC No Drone technology keeps cruising quiet. It finishes with quad 4.5in polished tips.

FAQ
Will it keep my C8 drive-mode exhaust settings?
Yes. The CORSA valve assemblies connect to the stock actuator motors, so the factory sound modes keep working without a check engine light.
Does it work on a C8 without NPP?
No. This 4-valve system is listed for C8s equipped with the factory NPP performance exhaust.
How loud is it?
CORSA lists +9 dB over stock with the valves open and 1 dB quieter than stock with the valves closed.
How long does shipping take?
Delivery times vary by part because many items ship directly from the manufacturer or distributor. Message us before ordering and we'll confirm current lead time.
Can I return it?
Yes. Returns are accepted within 30 days of delivery. The customer pays return shipping, and a restocking fee of up to 20% may apply.
