Borla ATAK Cat-Back Systems

Developing exhaust systems for the C8 Corvette presented Borla engineers with unique challenges, but the team was up to the challenge. Great care was taken to ensure the integrity and function of each system as well as the vehicle itself. ATAK Cat-Back System 140839BC includes both AFM and NPP dual mode exhaust valves. It features the ATAK sound level, Borla’s most aggressive sound for a more exciting driving experience without any drone. The system is built with both Polyphonic Harmonizer and SwitchFire technology. Borla’s Polyphonic Harmonizer technology utilizes patented units containing pipes of different diameters and lengths—to create multiple exhaust notes that harmonize to deliver a clean, rich, full-bodied sound. Completely eliminating the turbulent center intersection of a standard X-Pipe, Borla’s patented SwitchFire design truly blends the combustion pulses from both sides of the engine for improved performance and a custom aggressive sound.

Strategically placed heat shielding is included to prevent exhaust heat damage and protect your Corvette. The system comes with 4 in. Black Chrome on T-304 stainless steel tips. (Using Borla Stainless Steel Polish P/N 21461 is NOT recommended with these black chrome tips; Borla suggests cleaning the tips with hot water and a microfiber cloth.) Systems are also available with Bright Chrome on T-304 stainless steel tips, part number 140839; or carbon Fiber tips, part number 140839CF. This ATAK cat-back system is constructed using T-304 stainless steel to deliver the absolute best in performance and durability.
