Great care was taken to ensure the integrity and function of the system as well as the vehicle itself. Part number 140839 includes both AFM and NPP dual mode exhaust valves. It features the ATAK sound level, Borlas most aggressive sound. It provides a more exciting driving experience without any drone. It features 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. The system is constructed using T-304 stainless steel and is backed by our Million Mile Warranty. Choose your 4" Tip between Chrome, Black Chrome and Carbon Fiber
