XForce Varex exhaust systems deliver the power, sound, and style you desire. Fabricated with the strength and beauty of 304 stainless steel, they’re also designed for unrestricted flow and high performance. The systems feature XForce’s patented muffler innovation, Varex, that’s engineered with sophisticated butterfly valve mechanisms. This allows you to select optimal power output and sound levels to meet your desired preference by directing the flow of exhaust gases. You can choose to purr in street mode, roar in racing mode, or growl somewhere in between. XForce Varex exhaust systems look fabulous and hand the control of power and sound to you.
