Important Exhaust Notes
This MBRP Race Profile system removes the factory rear mufflers and exhaust valves. It does not retain the C8 Corvette Stingray’s NPP quiet and loud modes, so the aggressive exhaust sound remains present in every drive mode.
This is a complete C8 cat-back installation, not a simple rear muffler swap. Installation requires removal of the rear wheels, rear fascia, trunk liner, engine cover, and factory exhaust. Professional installation or experienced mechanical ability is recommended.

Use Overview
