This 3" diameter Mid-Section includes Active Exhaust Valves. The ATAK sound level delivers and an aggressive, race-bred sound without any drone. 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 sound. It fits with either the O.E. tail pipes or BORLA tail pipes 60727BC and 60727CFBA.
