AWE: 2017-2020 BMW 440i 3.0T Touring Edition Axle Back Exhaust Chrome Silver Tips 90mm
The AWE Tuning Touring Edition Exhaust is an axle-back system that leverages AWE Tuning's proprietary drone-cancelling solution, 180 Technology, to produce the perfect, drone-free exhaust note.
Sound Perfection: AWE Tuning 180 Technology
As exhaust gases exit the 340i / 440i engine and flow into an AWE Tuning 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.
