Carbon Fiber Exhaust Tips for the C8 Corvette Stingray, AutoSpeed NPP Cat-Back (2020-2026)
Want the back of your C8 to match the carbon fiber on the rest of it? The AutoSpeed Performance Series Cat-Back Exhaust, ASP-EXH-CBK-GM-0001-CF, is a valved cat-back for the 2020-2026 C8 Corvette Stingray with the 6.2L LT2 engine. It runs on your factory valves, so your quiet and loud modes stay exactly where they are.
Out back, four 4.5 inch carbon fiber tips sit in the rear fascia, single wall stainless under a carbon fiber shroud with the AutoSpeed logo printed on the face. The whole system weighs 11.5 pounds less than the factory cat-back.

Benefits
- 11.5 pounds lighter than the 77 pound factory Z51 cat-back it replaces.
- Carbon fiber at the rear to match the aero and trim already on the car.
- 22 more horsepower and 10 more lb-ft at the wheels, measured by AutoSpeed against your factory Z51 exhaust on 93 octane.
- Your drive mode still runs the exhaust. Quiet in Tour, open in Track, nothing to switch.
- Nothing is cut, drilled or welded. Your factory exhaust bolts right back on.
What to Expect
- Carbon fiber tips 4.5 inches across, filling the rear fascia.
- A louder, deeper note the moment the valves open, at cold start and under throttle.
- Carbon fiber tips that look like they came with the car.
- 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.
