Presenting The Best Sounding Exhausts on the Planet™ for the BMW G20 M340i: At the intersection of sophistication and aggression lies the Touring Edition Exhaust. A dual 3” T304L stainless steel downpipe-back configuration, the AWE Touring Edition Exhaust is the perfect dose of steel 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 downpipe. Translation: an impressive 65% increase in flow over stock that future proofs for downpipes of various sizes. 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’s this mean for you? You’ll be tuned into a pure, full-bodied B58 soundtrack unlike any other. Equipping a downpipe? Read this (seriously): The Touring Edition Exhaust is available as non-resonated or resonated. We recommend the non-resonated variant for vehicles equipped with the stock downpipe. If your M340i is equipped with an aftermarket downpipe, we recommend going resonated. Have the stock downpipe but plan to go aftermarket later? No worries, you can swap in the resonated midsections with ease via an AWE Resonator Conversion Kit.
