Why This Catback Exhaust

MAD engineered this system to deliver a more pronounced V8 exhaust note while maintaining the refinement expected from the F90 M5.

Constructed from premium 304 stainless steel, the system features smooth bends designed to maximize exhaust flow while minimizing unwanted drone.

The valved design works with your factory exhaust valves, allowing you to switch between a quieter, more subdued exhaust note and a louder, more aggressive sound when the valves are open.

MAD advertises gains of up to 15 WHP, with actual results depending on your vehicle's configuration and supporting modifications.

The system is finished with oversized 4-inch oval exhaust tips, available in three different finishes to complement your M5's rear end.

Deeper V8 sound. Factory valve control. No unwanted drone.
