Developing systems for the C8 Corvette presented Borla(r) engineers with unique challenges, but our team was up to the challenge. This 3" inlet Cat-Back(tm) system includes AFM ('20-'21)/ DFM ('22-'25) valves but does NOT include NPP dual mode exhaust valves. It features the aggressive ATAK(r) sound and provides a more exciting driving experience without any drone. It contains our Polyphonic Harmonizer and SwitchFire(r) technology. Borla(r) '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(r) 'S patented SwitchFire(r) 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 bright chrome on T-304 stainless steel tips and is also available with black chrome on T-304 stainless steel tips part number 140841BC, or carbon fiber tips, part number 140841CF.

Note: After installation of the Borla(r) system, the controllers for the AFM/ DFM valves in the exhaust system should be RE-CALIBRATED according to GM Document ID 5406413.
