At the intersection of sophistication and aggression lies the touring edition exhaust. A dual 3” T304L stainless steel down pipe back configuration, the AWE touring edition exhaust is perfect for drivers looking for straight-pipe performance while not sacrificing daily drivability: a deep, sophisticated exhaust note with zero drone at highway speeds.
Featuring a stamped stainless steel merge upstream equivalent to dual 3” tubing coming right off of the down pipe.
Translation: an impressive 65% increase in flow over stock.
Beyond the unique merge, the exhaust splits into dual 3” piping to allow optimal flow throughout the entire exhaust route.
Bringing up the rear, the touring edition features AWE’s patented drone-canceling solution, 180 technology®, which targets and omits drone-prone frequencies.
What does this mean for you? You’ll be tuned into a pure, full-bodied B58 soundtrack unlike any other.
As exhaust gases exit the B58 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 gases, 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. More on AWE 180 technology® in the tab above.
Have or Want an Aftermarket Down Pipe?
The touring edition exhaust is available as non-resonated or resonated. We recommend the non-resonated variant for vehicles equipped with the stock down pipe.
If your M340i or M440i is equipped with an aftermarket down pipe, we recommend going resonated.
Have the stock down pipe but plan to go aftermarket later? No worries, you can swap in the resonated midsections with ease via an AWE Resonator Conversion Kit.
We made it easy to convert between track and touring editions, resonated and non-resonated, and OE-to-quad tip configurations if you decide at a later date to change your volume or aesthetic.
