Borla ATAK Cat-Back Exhaust System (2020-2025 C8 Corvette and E-Ray) (140839BC)
Developing an exhaust system for the C8 Corvette required Borla engineers to rethink everything, and the result is one of the most advanced cat-back systems Borla has ever produced. Designed for 2020 to 2025 C8 Corvettes, including the E-Ray, this Borla ATAK Cat-Back Exhaust System delivers aggressive sound, improved performance, and factory level integration without unwanted cabin drone.
This system features a full 3 inch inlet design and integrates both AFM valves for 2020 to 2021 models, DFM valves for 2022 to 2025 models, and NPP dual mode exhaust valves. The ATAK sound profile provides a sharp, authoritative exhaust note under throttle while remaining controlled and comfortable during normal driving.
Borla’s Polyphonic Harmonizer Technology uses patented multi diameter and multi length internal pipes to produce layered exhaust tones that blend into a clean, rich, full bodied sound. Paired with Borla’s patented SwitchFire technology, which replaces a traditional X pipe and blends exhaust pulses from both sides of the engine, this system improves exhaust scavenging, throttle response, and overall performance.
Strategically placed heat shielding is included to protect surrounding components from exhaust heat, ensuring long term durability and reliability. The system is constructed from premium T 304 stainless steel and finished with 4 inch round black chrome tips on T 304 stainless steel. Bright chrome or carbon fiber tip options are also available.
After installation, the AFM, DFM, and NPP exhaust valve controllers must be recalibrated according to GM Document ID 5406413. Borla recommends having this recalibration performed by an authorized Chevrolet dealer.
Backed by Borla’s Million Mile Warranty, this system is built for enthusiasts who want uncompromising sound, engineering, and long term quality.
