SWITCHPATH™ AXELBACK:

The ultimate blend of aggression and sophistication—without the drone.

The AWE SwitchPath™ Axleback brings patented drone-canceling 180 Technology® to the S58-powered BMW X3/X4 M, delivering a tone that’s clean, deep, and composed while cruising—but rowdy when you want it to be.

Crafted from 3-inch, U.S.-sourced T304L stainless steel, the system features a valved SwitchPath™ muffler that seamlessly retains factory valve behavior—no harnesses or extensions needed. Minimal bends. Maximum flow. Push-button transformation.

The SwitchPath™ Axleback is engineered to begin at the factory cut point, making it compatible with the stock mid-section or any aftermarket mid-pipe that respects the OEM cut point.

If you’re chasing clean sound, drone-free cruising, and emissions compliance—this is it.
