The AWE 328i/330i & 428i/430i Touring Edition Axle-back Exhaust:

The AWE Touring Edition Axle-back Exhaust is a straight-through axle-back system available as dual outlet (single side, two tips) for the 328i/330i & 428i/430i, or quad outlet (two tips on each side) for the 328i & 428i, and leverages AWE’s proprietary drone-canceling solution,180 Technology®, to produce the perfect, drone-free exhaust note.

Perfect tone comes compliments of AWE 180 Technology®.

As exhaust gases exit the N20/26 and B48 engines 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.
