It bolts straight onto any 2020+ C8 equipped with the factory NPP valved exhaust, keeps the plug-and-play valve function GM designed, and gives the LT2 V8 two genuinely different personalities: close the valves for restrained cruising through the neighborhood, open them for an aggressive American V8 rumble with a hint of exotic mid-engine tone from Fabspeed's X-pipe design.\u003c\/p\u003e\u003ch3\u003ePower\u003c\/h3\u003e\u003cp\u003eThe factory NPP system chokes flow with the valves closed. On Fabspeed's DynoJet this system picked up peak gains of 4 whp \/ 6 lb-ft with valves open versus NPP-open — and 11.5 hp \/ 10 lb-ft (with curve gains up to 14 hp \/ 15 lb-ft) in valves-closed mode. It also drops about 20 lbs from the 76 lb factory system.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFits all 2020+ Chevrolet Corvette C8 models with the NPP factory valved exhaust\u003c\/li\u003e\n\u003cli\u003e3D laser scanned and CAD designed for exact OEM fitment\u003c\/li\u003e\n\u003cli\u003e3.0\" (76mm) CNC mandrel-bent T304L\/321 stainless steel, built in-house at Fabspeed Motorsport USA\u003c\/li\u003e\n\u003cli\u003ePlug-and-play exhaust valves; includes 2 AFM simulator plugs\u003c\/li\u003e\n\u003cli\u003eHeat shielding made from amorphous silica fiber wrapped in 321 stainless steel\u003c\/li\u003e\n\u003cli\u003eChoice of quad carbon fiber, polished, brushed, or ceramic-coated tips\u003c\/li\u003e\n\u003cli\u003e100% emissions legal; backed by the Fabspeed Lifetime Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cem\u003eNote: if a Check Engine Light appears after installation, the AFM\/NPP valves may need recalibration (GM document 5406413).
