Capristo Chevrolet Corvette (C6) Z06/ZR1 - Valved Exhaust

On the C6 with the NPP option, this valve is controlled by the onboard ECU. The valve opens based on RPM and throttle position. If you do not have a C6 with NPP, you need to order our CES-3 Kit separately. The iconic CAPRISTO Valved Exhaust System offers the best of both worlds through its capability to produce an aggressive exhaust note under acceleration, and a more subdued sound for city driving. At lower engine speeds and during cruise operation the valves are closed and produce a deeper exhaust note. At wide-open throttle the valves open, releasing the full symphony of the engine. If you have a C6 with the NPP Option: The opening or closing of the CAPRISTO valves are controlled by the engine ECU, therefore working in the same way that the original exhaust was designed to function. The OEM vacuum pipes fit directly into the CAPRISTO valve system. If you do NOT have a C6 with the NPP Option: you will need to fit the CES-3 Programmable Control Module for the exhaust valves, whi
