Blacked Out C8 Corvette E-Ray Cat-Back Exhaust, Black Tips for NPP Cars (2024-2026)
Ready to black out the back of your E-Ray? The AutoSpeed Performance Series Cat-Back Exhaust, ASP-EXH-CBK-GM-0001-BK, is a valved cat-back for the 2024-2026 C8 Corvette E-Ray 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 black chrome tips give your E-Ray the blacked out look, dark and aggressive against the rear fascia.

Benefits
- The blacked out rear, on a car that already wears more black trim than a Stingray.
- The LT2 gets a voice while the front motor keeps doing its job.
- 22 more horsepower and 10 more lb-ft at the wheels, measured by AutoSpeed against a factory Z51 exhaust on 93 octane.
- 9.5 pounds lighter than the 77 pound factory cat-back it replaces.
- Nothing is cut, drilled or welded. Your factory exhaust bolts right back on.
What to Expect
- Black tips filling the rear fascia at 4.5 inches across.
- A louder, deeper C8 exhaust note the moment the valves open, and the same silent pull away on the front motor.
- No change to Stealth mode, the regen or the silent pull away from a stop.
- 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. An E-Ray 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.
