The NPP valves stay, so your drive-mode switching is untouched. What comes out is the AFM valve, and the ECU still expects feedback from it, so the factory AFM actuator motors are retained on their brackets or electronically simulated at install. Handled at install, your dash stays clean. Skipped, the light comes on. Because of GM factory build tolerances some C8 Corvettes also want the GM valve relearn sequence afterwards, and that procedure is GM Document ID 5406413. Your installer will know it.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfirm your car has factory NPP before ordering.\u003c\/strong\u003e This system is built for the Stingray that came with NPP, the factory dual-mode exhaust option. A car built without NPP takes a different CORSA system.
