Description
Overview
Engineered specifically for the 2018-2023 BMW M5 Sedan (4.4L, AWD), the AWE Tuning SwitchPath™ Cat Back Exhaust System Kit transforms the character of one of BMW’s most potent sedans without asking you to compromise. This is a complete valved catback exhaust system built around dual 3″ CNC mandrel-bent .065″ wall T304L stainless steel tubing that runs from the downpipes to the tip outlets, with a precision-engineered X-pipe in between for a refined, balanced tone. If you have been trying to shop for exhaust hardware that pairs OE-level integration with genuine performance exhaust attitude, this is the answer.
Valved SwitchPath™ Technology
The defining feature here is the valved rear sections. The SwitchPath™ Cat Back retains all of the M5’s factory valve behavior, so the exhaust responds exactly as intended when you change driving modes or use the exhaust button on the console. Quiet and composed when you want it, aggressive and unmistakably M when you don’t — all controlled the way BMW designed it, with no aftermarket workaround. Because valve behavior is preserved, you get an exhaust system that feels genuinely factory-integrated rather than bolted on.
Included AWE Performance Mid Pipes
The kit includes AWE Performance Mid Pipes that replace the factory mid section with a 3″ stainless steel X-pipe. That X-pipe is part of the SwitchPath™ Cat Back configuration, delivering the crossover flow and tonal balance that gives this car exhaust its signature voice. It’s a complete exhaust pipe solution from downpipes back, not a partial upgrade.
Diamond Black Tips
Every configuration finishes with four 4″ slash-cut tips in a Diamond Black finish. Each tip carries the AWE logo and is double-walled to ensure a mirror-quality finish even under hard, sustained use. Better still, the tips are individually adjustable, letting you set the depth into the bumper according to personal taste for a truly dialed-in appearance.
