Product Description

The Borla 140841BC is an ATAK cat-back exhaust system engineered specifically for the 2020-2025 Chevrolet C8 Corvette Stingray without factory NPP dual-mode exhaust valves. ATAK -- Acoustically Tuned Applied Kinetics -- is Borla's most aggressive sound profile, producing the highest dB levels of any Borla series while leveraging Polyphonic Harmonizer Technology and SwitchFire design to eliminate harshness and drone. Polyphonic Harmonizer units use pipes of varying diameters and lengths that harmonize to produce a clean, full-bodied exhaust note, while SwitchFire blends combustion pulses from both sides of the mid-mounted V8 for improved performance and a distinctive sound profile.

Built from T304 stainless steel with strategically placed heat shielding to protect the C8's mid-engine bay components, this system installs without cutting or modification. The kit includes AFM valves for 2020-2021 models and DFM valves for 2022-2025 models, but does not include NPP valves -- NPP-equipped owners should instead order Borla 140838BC. After installation, valve actuator recalibration is required per GM Document ID 5406413, which Borla recommends completing at a Chevrolet dealer. Backed by Borla's million-mile warranty. Made in USA.
