The C8 already has valves in its exhaust, which means a replacement system has to work with the car's electronics rather than around them. This ATAK cat-back keeps the NPP valve function and adds SwitchFire technology and a Polyphonic Harmonizer, so the driver still gets a quiet setting for the neighborhood and the loudest setting Borla offers when the valves open.

Borla ATAK Cat-Back Exhaust System Features:

• Fits 2020-2025 Chevrolet Corvette C8 6.2L V8, automatic transmission, rear wheel drive.
• Requires factory NPP valves; do not install on cars without them.
• Covers AFM valves on 2020-2021 cars and DFM valves on 2022-2025 cars, and includes 2024-2025 E-Ray.
• Includes a Polyphonic Harmonizer and SwitchFire technology for driver-selectable sound.
• Valve actuator recalibration is required after installation.
• System ships in two boxes.
