Universal Hydroformed Switchfire X-Pipe 3" ID 3" OD Outlets W/O Notches (60746)Description The Borla Universal Hydroformed SwitchFire X Pipe (Part # 60746) is a revolutionary component designed for builders of high performance custom exhaust systems. Unlike standard X Pipes that feature a turbulent center intersection, the patented SwitchFire design completely eliminates the collision of exhaust gases. Instead, it uses hydroformed internal passages to truly blend and merge the combustion pulses from both sides of the engine.
