The dual wall holds the outer surface cooler than a single wall tip, which is why the black keeps its depth through years of heat cycles. Against dark wheels the tips settle into the car's line; against a light car they draw the eye straight to the tail. They unbolt from the system on their own whenever you want a different face back there.\u003c\/p\u003e\n\n\u003ch3\u003eImportant Exhaust Notes\u003c\/h3\u003e\n\n\u003cp\u003eYour car has two separate sets of exhaust valves, and this system treats them differently. The NPP valves live inside the mufflers, so they leave with the mufflers; their factory actuator motors stay with the car, retained on brackets or electronically simulated at install so the ECU still sees what it expects. The AFM valve is separate hardware and it stays, actuator and all, which is why economy-mode cruise keeps its factory damping here. Handled at install, your dash stays clean. Skipped, a check engine light follows.\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. A car built without NPP takes a different CORSA system. 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 Quiet start and drive-mode switching leave with the mufflers, and RSC is not in this configuration. What stays behind is the AFM damping, not a quiet mode.\u003c\/li\u003e\n\u003cli\u003eBecause of GM factory build tolerances, some C8 Corvettes want the GM valve relearn sequence after an exhaust install. That procedure is GM Document ID 5406413 and your installer will know it.\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.
