A 3” T304L stainless steel downpipe-back configuration, the Touring Edition Exhaust is the perfect dose of steel for drivers looking for straight-pipe performance, a deep, sophisticated exhaust note, and zero drone at highway speeds. Featuring an integrated front pipe, robust midpipe resonator, thick-walled T304L stainless steel, and a special iteration of AWE’s 180 Technology® bespoke for the DE5 in the rear, the Touring Edition is the do-it-all configuration for everyday drivers. Thanks to AWE’s patented drone-canceling 180 Technology®, the Touring Edition keeps all of the commotion to the rear of the vehicle where it belongs, and destroys drone-prone frequencies that would otherwise resonate within the cabin at highways speeds – all packaged perfectly to fit within the undertray of the bumper with plenty of clearance. The Touring Edition, and the 180 Technology® within it, were both developed for use with and without an aftermarket catted downpipe. As exhaust gases exit the K20 engine and flow into an AWE 180 Technology equipped resonator, they pass through strategically located ports, and into reflection chambers. Sound waves, carried by these exhaust gasses, bounce off the walls of the reflection chambers. By controlling the size and location of the ports and the chambers, we also control when the sound waves exit the chambers. The specific timing of when the reflected sound waves rejoin the main exhaust flow creates a one-hundred-and-eighty-degree out-of-phase sound wave that cancels out problematic frequencies. All of this with a straight-through design- in other words, all the power, none of the drone. Throw in that it was designed and manufactured in the USA, and AWE's famous diamond black or chrome silver tips, and you're looking at the best sounding, longest lasting, and best fitting exhaust for the DE5 - all backed by AWE's No CEL and Perfect Fitment Guarantee, and a Lifetime Warranty.
