This AWE Tuning mid-pipe replaces the stock center resonator (front muffler) section with an x-pipe constructed of of 3" high-flow T304 stainless steel tubing. Removing the factory front muffler improves exhaust flow and adds to the sporty exhaust note of your AWE rear exhaust.
This pipe clamps onto the outlets of the factory catalytic converters/downpipes, and is compatible with the AWE Tuning rear exhaust for F90 M5 models.
