Description
Overview
The AWE Tuning SwitchPath™ Cat Back Exhaust System Kit transforms the 2018-2023 BMW M5 (Sedan, 4.4L, AWD) into a fully controllable powerhouse of sound. Engineered as a complete catback exhaust system, it pairs dual 3” CNC mandrel-bent .065” wall T304L stainless steel tubing with a precision-engineered X-pipe, delivering the kind of refined, high-performance exhaust flow that discerning M5 owners demand. Whether you’re chasing a deeper daily-driver tone or an aggressive open-throttle roar, this valved car exhaust puts the choice at your fingertips.
At the heart of this exhaust system are valved rear sections. Unlike many aftermarket setups, the SwitchPath™ design retains all of the M5’s native valve behavior when you change driving modes or use the exhaust button on the console. That means factory-integrated control with genuine performance exhaust character — no compromises, no clunky workarounds.
Key Benefits
Included AWE Performance Mid Pipes replace the factory mid section with a 3” stainless steel X-pipe, coming standard in the Cat Back SwitchPath™ configuration. From the downpipes to the tip outlets, every exhaust pipe in this kit is built for durability and flow, crafted from T304L stainless steel to resist corrosion and handle the heat of hard driving.

Tips & Finish Options
All four tips measure 4” in diameter, are slash-cut, and carry the AWE logo. Double-walling ensures they hold their mirror finish even under hard usage, while individual adjustability lets you dial in how far each tip sits into the bumper — a small detail that makes a big difference in the final look. The Chrome Silver finish delivers a clean, factory-plus aesthetic that complements the M5’s aggressive stance.
