AWE Tuning Axle-Back Exhaust SwitchPath for BMW X3 M, X3 M Competition, X4 M, and X4 M Competition models leverages 3-inch U.S.-sourced T304L stainless steel and a valved SwitchPath muffler that preserves factory valve behavior without harnesses or extensions. The system uses a clean, straight-through design with minimal bends for maximum flow, while a bespoke X-pipe in the non-resonated Performance Mid Pipes adds a refined S58 tone when paired with SwitchPath. The system can connect with the factory axleback or AWE Axleback, and mid pipes are designed to work with the OEM break point. 50-state emissions-compliant and handcrafted in-house at AWE with a lifetime warranty and No CEL guarantee.
