Flat cut means the tip is cut straight across, so all four tips face you evenly from behind the car. A soft cloth keeps the weave clean, and the tips unbolt from the system on their own if you ever want to refresh or swap them.\u003c\/p\u003e\n\n\u003ch3\u003eImportant Exhaust Notes\u003c\/h3\u003e\n\n\u003cp\u003eA check engine light is the thing C8 owners ask about most before they buy a valve delete, so here is the direct answer. Deleting the AFM valve takes out the hardware, not the ECU's expectation of it, so your installer either keeps the factory actuator motors on their brackets or fits electronic simulators in their place. 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 RPO NPP status before ordering.\u003c\/strong\u003e This system fits a Stingray that left the factory without NPP. These parts do not fit a 2021 or later car equipped with NPP from the factory, and fitting one there will set a check engine light. Send us the VIN and we will check yours before you order.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOne volume, all the time.\u003c\/strong\u003e The AFM valve is the hardware that softened 4-cylinder cruise; with it deleted, light resonance can be present in 4-cylinder economy mode, and RSC no-drone technology is not in this configuration.\u003c\/li\u003e\n\u003cli\u003eThis is a bolt-up system: it installs at the factory hangers and mounting locations with the hardware supplied in the kit.
