2020-2024 Chevrolet Corvette (C8) Cat-Back Exhaust System ATAK

Developing systems for the C8 Corvette presented BORLA engineers with unique challenges but our team was up to the challenge. This 3" inlet Cat-Back system includes AFM ('20-'21)/ DFM ('22-'25) valves but does NOT include NPP dual mode exhaust valves. It features the aggressive ATAK sound. It provides a more exciting driving experience without any drone. It contains our Polyphonic Harmonizer and SwitchFire technology. BORLA 'S Polyphonic Harmonizer Technology utilizes patented units that contain 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 sound. Strategically placed heat shielding is included to prevent exhaust heat damage and protect your Corvette. It comes with 4" round black vhrome on T-304 stainless steel tips and is also available with bright hrome on T-304 stainless steel tips part number 140841 or carbon fiber tips part number 140841CF. The system is constructed using T-304 stainless steel and is backed by our Million Mile Warranty. System ships in 2 boxes. Note: After installation of the BORLA system the controllers for the AFM/ DFM valves in the exhaust system should be RE-CALIBRATED according to GM Document ID 5406413. BORLA recommends taking your car to the nearest Chevrolet dealer for the recalibration service.
