Description
14-21BMW F22 M235i / M240i Touring Edition Axle-Back Exhaust – Diamond Black Tips (90mm)
Touring Edition Axle-Back Exhaust:
The AWE Touring Edition Exhaust is an axle-back system that leverages AWE’s proprietary sound cancellation solution, 180 Technology, to produce the signature, sophisticated, drone-free exhaust note.
AWE’s Pantented 180 Technology:
As exhaust gases exit the N55/B58 engines and flow into an AWE180 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.
Made in PA, USA:
Engineered, designed, and manufactured in-house at AWE using US-sourced .065-wall T304L stainless steel to achieve a tone deeper than everyone else.
