Product Description

 

 

The AWE SwitchPath™ Cat-Back Exhaust transforms your BMW’s exhaust note and performance with a valved, high-flow design engineered specifically for S58-powered M3 and M4 models. Crafted from premium 3″ T304L stainless steel with a precision X-pipe and drone-cancelling 180 Technology®, this system delivers a deeper, more commanding tone under throttle while remaining refined at cruise. The SwitchPath™ valved muffler integrates seamlessly with factory valve controls—no extra remotes or modules required—offering driver-controlled acoustics through OEM drive modes. Dual 4.5″ double-walled Chrome Silver or Diamond Black slash-cut tips add a bold rear aesthetic that complements performance-oriented styling. Emissions compliant for all 50 states with ball-socket mounts for easier installation.

Fitment Notes

  • Designed for select BMW G8x M3 / M4 (S58 engine) models
