The SwitchPath™ Cat Back Exhaust features dual 3” CNC mandrel-bent .065” wall T304L stainless steel tubing from downpipes to tip outlets with a precision-engineered X-pipe in between. Equipped with valved rear sections, the SwitchPath™ Cat Back retains all of the M5’s valve behavior when changing driving modes and/or using the exhaust button found on the console. The AWE Performance Mid Pipes replace the factory mid section with a 3” stainless steel X-pipe, and are included in the Cat Back SwitchPath™ configuration. All tip options are 4", slash-cut, and include the AWE logo and double-walling to ensure a mirror finish even under hard usage. All tips are individually adjustable, allowing depth into the bumper to be set according to personal taste.
