Borla 140839CF ATAK Cat-Back Exhaust System for Chevrolet Corvette C8

2024-2026 includes E-Ray. 2027 includes Grand Sport & Grand Sport X. Developing systems for the C8 Corvette presented some unique challenges. This 3" inlet Cat-Back system includes both AFM ('20-'21)/ DFM ('22-'27) valves and NPP ('20-'27) dual mode exhaust valves. It features the aggressive ATAK sound for an exciting driving experience with no drone inside the vehicle. It features 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 aggressive sound. Strategically placed heat shielding is included to prevent exhaust heat damage and protect your Corvette. It comes with quad (2 each side) 4" round carbon fiber tips with bright centers. Systems are also available with bright chrome on T-304 stainless steel tips, or black chrome on T-304 stainless steel tips. 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 and NPP 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.
