C7 Corvette Z06 CORSA Xtreme NPP Axle-Back Exhaust 14777BLK – Black Tips (2015–2019)
The CORSA Xtreme 14777BLK is a valved axle-back exhaust system engineered specifically for C7 Corvette Z06 models equipped with factory NPP. It delivers CORSA’s most aggressive exhaust tone when the valves are open, while retaining a quieter cruising mode when closed — all without interior drone.

Why Choose CORSA Xtreme with NPP
This system combines CORSA’s patented Reflective Sound Cancellation® (RSC®) technology with OEM NPP valve control. In Touring mode, exhaust volume is reduced for street driving. In Sport or Track mode, the valves open to unleash a sharp, race-inspired exhaust note — without the low-frequency drone common in other systems.

- Factory integration: Works seamlessly with OEM NPP operation
- Black Pro-Series tips: Aggressive, stealth appearance
