C8 Corvette 3.0in Cat-Back Quad 4.5in Pro-Series Tips | CORSA Performance

This exhaust is made for drivers seeking an ultra-aggressive exhaust note without resonance caused by 4 cylinder economy mode operation. CORSA’s AFM only C8 cat back exhaust systems is designed to eliminate restrictions, maximize weight savings, and bring the noise while eliminating resonance from 4 cylinder mode.

What are AFM Valves?

Active Fuel Management (AFM) improves gas mileage by deactivating engine cylinders. This causes a resonance which can be unpleasant.

Choose this option if you want to maintain a comfortable cabin sound or are sensitive to 4Mode frequencies.

What is NPP?

NPP is the product option code for Chevy’s Dual Mode (Bi-Model) exhaust upgrade that opens and closes a valve to control exhaust sound.

CORSA’s NPP valve assemblies bolt directly to stock actuator motors. Choose this option if you need quiet start, C8 is heavily modified, or want to be stealthy.
