C8 Corvette Stingray AutoSpeed Exhaust with NPP - Black Chrome Tips
Blacked Out C8 Corvette Stingray Cat-Back Exhaust, Black Tips for NPP Cars (2020-2026) Ordered your Stingray with NPP and want to upgrade the sound? The AutoSpeed Performance Series Cat-Back Exhaust, ASP-EXH-CBK-GM-0001-BK, is a valved cat-back for the 2020-2026 C8 Corvette Stingray with the 6.2L LT2 engine. Keep your NPP function and maintain your quiet and loud modes. Roll into the throttle with the valves open and there is real volume behind you, well past the factory NPP exhaust on its own. Out back, four 4.5 inch black chrome tips give your Stingray the blacked out look, dark and aggressive against the rear fascia. AutoSpeed also put this system on a dyno and a scale, so there are real numbers behind the sound.

The valves follow your drive mode. 22 more horsepower and 10 more lb-ft at the wheels, measured by AutoSpeed against your factory Z51 exhaust on 93 octane. 9.5 pounds lighter than the 77 pound factory Z51 cat-back it replaces. Nothing is cut, drilled or welded. Your factory exhaust bolts right back on. What to Expect A louder, deeper C8 Corvette exhaust note the moment the valves open, at cold start and under throttle. The blacked out look out back, 4.5 inch black tips filling the rear fascia. A highway volume you can enjoy, the valves closed and the exhaust running through three chambers before the tips. Important Exhaust Notes Your car supplies the valve actuators. The kit ships valve bodies without motors and reuses your factory AFM and NPP actuators. A Stingray without factory NPP cannot use this system. No tune is required. A valve relearn is required. Your AFM and NPP valves are relearned with an OBD scan tool, per GM Document ID #5406413. Skipping it can cause a check engine light and damage the valves. Any Chevrolet dealer can do it. Professional installation recommended. About three hours on a lift, with the rear wheels, wheel liners, air deflectors and rear bumper fascia off. The install guide gives a torque figure for every joint, 44 lb-in through 60 lb-ft, including 75 lb-in on each actuator bracket. Have a torque wrench ready for those figures. Re-torque the tip clamps after the first heat cycle.
