The AWE Touring Edition Cat Back is for drivers who like their BOXER rumble to be deep, hearty, and full of crackles all without any interior drone at cruising speeds. Comprised of 3” T304L stainless steel with a hefty wall thickness of .065”, the Touring Edition features a bullet-style resonator in the mid-pipe and a set of patented 180 Technology ® resonators residing in the rear to decimate any drone-prone frequencies from the exhaust note while keeping the flow of power uninterrupted. Thanks to the design and construction of 180 Technology ® resonators, the internals will not break down and degrade over time causing tone change. Full-bodied rumble for life from the point of installation. This configuration provides the best ratio of interior refinement and exterior rumble on the market. Each system comes complete with 4" slash-cut tips, with your choice of diamond black or chrome silver. And AWE made it easy to convert from a Touring Edition to a Track Edition, or vice versa, if you decide at a later date to turn it up or turn it down. All this plus 50 state emissions compliance, AWE's Fitment Guarantee, No Check Engine Light Guarantee, and the AWE Lifetime Warranty.
