Borla Cat-Back Exhaust System ATAK Black Chrome (140839BC) - 2020-2026 Chevrolet Corvette Stingray & E-Ray
Give your C8 Corvette an aggressive race-inspired exhaust tone and premium black chrome styling with the Borla 140839BC ATAK Cat-Back Exhaust System. Designed specifically for the 2020-2026 Chevrolet Corvette Stingray and 2024-2026 Corvette E-Ray, this advanced exhaust system delivers Borla's most aggressive ATAK sound while maintaining a comfortable, drone-free driving experience.
Developed specifically for the unique mid-engine Corvette platform, the Borla 140839BC combines innovative exhaust technology with premium materials for maximum performance, sound quality, and durability. This 3" inlet Cat-Back system includes both AFM ('20-'21) / DFM ('22-'26) valves and factory NPP dual mode exhaust valves to retain full OEM exhaust functionality.
The system utilizes Borla's patented Polyphonic Harmonizer and SwitchFire technology for superior exhaust tone and optimized exhaust flow. The Polyphonic Harmonizer uses specifically tuned pipe diameters and lengths to create harmonized exhaust frequencies for a rich, full-bodied sound. Borla's patented SwitchFire design eliminates the turbulent center intersection found in conventional X-Pipes, blending combustion pulses more efficiently for improved exhaust scavenging, increased performance, and a refined aggressive tone.
Strategically placed heat shielding helps protect surrounding components from excessive heat while quad 4" round black chrome T-304 stainless steel tips provide an aggressive, high-end appearance.
Constructed entirely from premium T-304 stainless steel, the Borla 140839BC offers outstanding durability, corrosion resistance, and long-term reliability. The system ships in two boxes and is backed by Borla's Million Mile Warranty.
