AWE Tuning - SwitchPath Catback Exhaust - BMW F8X M3/M4
We made the S55 sound epic with the valves closed, and with them open… again! All while remaining emissions-compliant. Presenting the second generation of SwitchPath Exhaust for the BMW F8X M3 and M4. Minimal bends, maximum flow, and push-button attitude. The SwitchPath Exhaust is a true catback configuration comprised of 3-inch and 2.5-inch U.S.-sourced T304L stainless steel, a precision x-pipe, and a valved SwitchPath muffler tuned specifically for the S55. Beginning after the secondary catalysts, the precision X-pipe immediately helps smooth the S55 of its infamous rasp, allowing the tone to be further refined by the bespoke muffler in the rear.
