C7 Corvette ZR1 Corsa 14777 - NPP (2019)

C7 Corvette ZR1 CORSA Xtreme NPP Axle-Back Exhaust 14777 (2019) The CORSA Xtreme 14777 is a valved axle-back exhaust system designed specifically for the 2019 C7 Corvette ZR1 equipped with factory NPP. It delivers CORSA’s most aggressive exhaust sound when the valves are open, while retaining a quieter cruising mode when closed — all without interior drone.
