X MARKS THE SPOT. THE SWITCHPATH™ EXHAUST SUITE FOR THE F9X X3 M & X4 M.
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.
Perfect tone, compliments of AWE 180 Technology®:
Keeping the aggression out at the rear of the X3/4 M, and out of the cabin, is AWE’s patented drone-canceling solution, 180 Technology®. As exhaust gases exit the S58 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.
NON-RESONATED PERFORMANCE MID PIPES:
Crank up the character.
Ditch the stock mid-section for a pair of 3-inch, non-resonated mid-pipes featuring a bespoke X-pipe designed to unlock a more aggressive, refined tone. When paired with the SwitchPath™ Axleback, the result is a deep, smooth soundtrack with no trace of rasp.
The Non-Resonated Performance Mid Pipes are engineered to begin right behind the factory secondary catalysts, and they’re compatible with both the factory axleback and any system that aligns with the OEM cut point.
LET'S TALK TIPS:
Finish it off with signature 4.5” double-walled, slash-cut tips in your choice of chrome silver or diamond black—each stamped with the AWE logo and individually adjustable for precise placement.
POWER TO THE PAVEMENT:
SwitchPath™ and the Non-Resonated Performance Mid Pipes unlock dyno-proven gains of +9 hp and +2 lb-ft of torque at the wheels.
