Turn up the two:

The AWE Exhaust Suite for the BMW G42 M240i unlocks the B58 with a full 3” straight-through configuration engineered for more flow, more power, and more attitude without compromise. The result is a 65% flow increase over stock, with max gains of 10 hp and 17 ft-lbs of torque at the wheels on stock software.

Touring or Track:

Choose your volume. The Touring Edition features AWE’s patented 180 Technology® to cancel drone-prone frequencies while delivering a deep, refined soundtrack under throttle. The Track Edition ditches the 180 Technology® resonators for a lighter, louder, rowdier experience built for drivers who want the G42 turned all the way up.

Perfect tone, compliments of AWE 180 Technology®

Keeping the aggression at the rear of the M240i, and out of the cabin, is AWE’s patented drone-canceling solution, 180 Technology®. As exhaust gases exit the B58 engine 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.

Let’s talk tips:
