With the valves open, the system delivers an aggressive V8 exhaust note; close the valves and the system becomes significantly more restrained for cruising and neighborhood driving.\u003cbr\u003e\n \u003c\/p\u003e\n\n\u003cp\u003e \u003cbr\u003e\n \u003c\/p\u003e\n\n\u003cp\u003eKey Features\u003c\/p\u003e\n\n\u003cp\u003eUp to +14 HP and +15 lb-ft of torque across the power curve\u003c\/p\u003e\n\n\u003cp\u003e20 lb \/ 9 kg lighter than the factory NPP exhaust\u003cbr\u003e\nFull 3-inch \/ 76mm exhaust tubing\u003c\/p\u003e\n\n\u003cp\u003eT304L \/ 321 stainless steel construction\u003cbr\u003e\nPlug-and-play exhaust valves retain factory NPP functionality\u003cbr\u003e\n3D laser scanned and CAD designed\u003cbr\u003e\nCNC mandrel-bent tubing\u003cbr\u003e\nHigh-temperature amorphous silica fiber heat shielding wrapped in 321 stainless steel\u003cbr\u003e\nIncludes 2 AFM simulator plugs\u003c\/p\u003e\n\n\u003cp\u003eMultiple exhaust tip finishes available\u003cbr\u003e\nDirect bolt-on installation\u003cbr\u003e\nNo cutting or welding required\u003cbr\u003e\nFabspeed Lifetime Warranty\u003c\/p\u003e \n\n\n\u003cp\u003eDyno-Proven Performance\u003cbr\u003e\nCompared with the factory NPP exhaust with both systems' valves open, Fabspeed recorded peak gains of 4 WHP and 6 lb-ft of torque.\u003cbr\u003e\nThe difference becomes considerably larger with the valves closed. Fabspeed recorded 11.5 WHP and 10 lb-ft of peak torque gains, with gains across the curve reaching as much as 14 HP and 15 lb-ft of torque. This allows the Maxflo system to maintain strong exhaust flow even when operating in its quieter valve setting. \u003cbr\u003e\nFactory NPP Valve Integration\u003cbr\u003e\nThe system uses plug-and-play exhaust valves designed to function with the Corvette's factory NPP exhaust controls. This allows the driver to continue changing the exhaust character through the vehicle's factory settings rather than relying on a separate aftermarket remote. \u003cbr\u003e\nOpen the valves when you want the full aggressive exhaust note, or close them when you want a more restrained sound for cruising.\u003cbr\u003e\n20 LB Weight Reduction\u003cbr\u003e\nThe factory NPP exhaust weighs approximately 76 lbs \/ 34.5 kg. Fabspeed's Maxflo system reduces that weight by approximately 20 lbs \/ 9 kg, removing significant mass from the rear of the vehicle. \u003cbr\u003e\n3-Inch High-Flow Construction\u003cbr\u003e\nThe Maxflo system features 3.0-inch \/ 76mm T304L and 321 stainless steel tubing, with components manufactured in-house by Fabspeed Motorsport USA.\u003cbr\u003e\nCNC mandrel-bent tubing provides a smooth exhaust path, while the larger-diameter design allows the LT2 V8 to breathe more freely. The system also incorporates high-temperature heat shielding constructed from amorphous silica fiber wrapped in 321 stainless steel to help manage exhaust heat in the C8's tightly packaged mid-engine layout. \u003cbr\u003e\nAggressive Valved Exhaust Sound\u003cbr\u003e\nFabspeed designed the system with two distinct personalities. With the valves open, the C8 gains a deeper, throatier American V8 sound with an exotic character introduced by the X-pipe design.\u003cbr\u003e\nClosing the valves produces a more restrained exhaust note for highway cruising, city driving, or situations where maximum volume isn't desired. \u003cbr\u003e\nExhaust Tip Options\u003cbr\u003e\nAvailable tip finishes include:\u003c\/p\u003e\n\n\u003cp\u003ePolished Stainless Steel\u003cbr\u003e\nCarbon Fiber\u003cbr\u003e\nSatin Black\u003cbr\u003e\nTitanium\u003c\/p\u003e\n\n\u003cp\u003eThe system uses a quad-tip configuration to complement the factory C8 rear-end design. \u003cbr\u003e\nAFM \u0026amp; Valve Recalibration\u003cbr\u003e\nTwo AFM simulator plugs are included. Fabspeed recommends operating the vehicle in 8-cylinder mode to minimize the possibility of a Check Engine Light.\u003cbr\u003e\nFollowing exhaust installation, the C8's AFM and NPP exhaust valves may require recalibration if a CEL appears. This procedure can be performed using a compatible professional scan tool or by a GM dealer using GM Document 5406413. \u003cbr\u003e\nInstallation\u003cbr\u003e\nDesigned as a straightforward bolt-on replacement with no cutting or welding required.
