BORLA®'S unique SwitchFire™ X-Pipe assembly is designed to replace the OE resonator only on this application. 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, while further tuning sound via our breakthrough Polyphonic technology. The result is an aggressive custom sound and improved power. Built from premium T-304 stainless steel, superior to T-400 series (such as 409), to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit.
