AWE Tuning BMW F3x 328i / 428i Touring Edition Exhaust
The AWE Tuning Touring Edition Exhaust is straight-through axle back system available as either dual outlet (single side, two tips) or quad outlet (two tips on each side), and leverages AWE Tuning’s proprietary drone-cancelling solution, 180 Technology, to produce the perfect, drone free exhaust note. If you’re unfamiliar with 180 Technology, learn more through this brief 180 Technology video.
Sound Perfection: AWE Tuning 180 Technology
Perfect tone comes compliments of AWE Tuning 180 Technology
As exhaust gases exit the #28i 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. More on AWE Tuning 180 Technology in the tab above.
Optional Extra AWE Tuning Performance Mid Pipes
The Resonated Performance Mid Pipe is offered as an option to compliment the Touring Edition Exhaust. With the Resonated Performance Mid Pipe in place, the Touring Edition axle back is transformed into a full downpipe-back system, replacing the factory mid section (and the secondary catalytic converter on N26 motors) with straight-through 3” T304 stainless steel tubing.
All F3x 428i systems are 80mm and double walled, available in either Chrome Silver or Diamond Black.
