AWE SwitchPath Cat-Back Exhaust for 2015-2020 BMW M3/M4 (F8X) - 102mm Diamond Black Tips

Fits 2015-2020 BMW M3 and M4 (Base, CS, GTS).

The AWE SwitchPath Cat-Back Exhaust for the BMW F8X platform provides a sophisticated performance solution that utilizes factory valving to retain full M-Sport button functionality. This system features a precision-engineered X-pipe designed specifically to unlock a cleaner, more exotic tone from the S55 engine, replacing the often-muffled factory note with a signature AWE sound profile. The 50-state legal cat-back design keeps all factory catalysts intact while delivering measurable performance improvements.

Handcrafted from U.S.-sourced .065-inch wall T304L stainless steel, this exhaust uses 3-inch CNC mandrel-bent tubing for optimal flow. The system is finished with 102mm double-walled, slash-cut tips in Diamond Black, providing a durable and high-end aesthetic. Engineered for a unified fitment across both Euro OPF and non-Euro spec vehicles, it includes AWE’s No Check Engine Light and Perfect Fitment guarantees.
