CORSA Active Valve 2.75" Valve-Back Exhaust with Polished 4.5" Quad Tips (14776) - 2014-2019 Chevrolet Corvette C7 & 2017-2019 Grand Sport
Give your C7 Corvette a wider range of exhaust sound while retaining the factory NPP functionality with the CORSA Active Valve 2.75-Inch Valve-Back Exhaust System. Designed for 2014-2019 Chevrolet Corvette C7 6.2L V8 models equipped with the factory NPP option, this system combines CORSA RSC® Technology with integrated active exhaust functionality to let the car transition between refined Touring behavior and a much more aggressive Track-style exhaust note.
CORSA's Active Valve design allows the driver to take advantage of the Corvette's multiple driving modes while maintaining a No Drone driving experience. With more than 17 dB of volume difference between the valve-open and valve-closed settings, the 14776 system gives the C7 a broad range of sound without eliminating the factory-controlled exhaust character.

Active Valve NPP Sound Control
The CORSA 14776 is engineered to work with the C7 Corvette's factory NPP system, allowing the driver to retain the vehicle's multiple exhaust personalities. Depending on the selected driving mode and valve position, the exhaust can remain more subdued for Touring use or open up for a significantly more aggressive sound in performance-oriented settings.
The difference between valve-open and valve-closed operation exceeds 17 dB, giving the system a substantial range of volume while preserving the factory-style active exhaust control.
No Drone RSC® Technology
CORSA combines its Active Valve system with RSC® Technology to control unwanted frequencies that can create exhaust drone. This allows the system to deliver a more aggressive exterior exhaust note when the NPP valves are open while maintaining a more comfortable cabin during cruising.
Factory NPP Integration
This Valve-Back system integrates directly with the factory NPP valve actuators and requires the vehicle to have been equipped with NPP from the factory. CORSA retains the GM factory axle pipes, and the exhaust attaches behind the factory axle-pipe AFM valves.
4.5-Inch Polished Quad Tips
The system finishes the rear of the C7 with four 4.5-inch polished Pro-Series exhaust tips. Their dual-wall slash-cut design provides a clean, aggressive appearance that complements the Corvette's factory quad-exit layout while adding CORSA's premium finishing detail.
