Axleback exhaust systems generally include what's behind your rear axle. These are among the easiest of exhaust upgrades to install, and give you an instant upgrade in sound.
The SwitchPath Catback Exhaust for the F97 X3 M from AWE offers a perfectly balanced and tuned exhaust that will deliver power when needed without droning at cruising speeds. By replacing the factory muffler, you will uncover the pure sound of the S58 engine. This exhaust is perfect for those who want a more aggressive response when getting on the throttle, but don't want to wake up the neighbors. The SwitchPath™ Technology utilizes factory valving and the M-Sport button to adjust tone on the fly. 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. AWE's optional Non-Resonated Performance Mid Pipes can be included to create a full cat-back exhaust system. 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.

The engineers at Akrapovic have retained the dual-mode exhaust flap control from the original system. This allows the vehicle to have a more civilized, but deeper than stock sound at low speed. However, at higher RPM (or when selecting the S mode on the gearshift) the muffler is bypassed, creating a deep and sporty sound much more in keeping with the personality of the car.

The Akrapovic Sound Kit is a wireless exhaust valve control system that allows you full control over the valve system in your titanium Akrapovic exhaust. This enables you to open the exhaust valve when you want to turn as many heads as possible or keep it closed when your out for an easy Sunday drive.
