Sound and drivability
At light throttle the Dinan valved exhaust keeps cabin noise civil, limiting drone for comfortable daily driving. Lean into the throttle and the valves open to unleash the signature BMW M bark with a richer, more aggressive tone. The result is the best of both worlds, a refined everyday experience with genuine performance sound when you press on.
Engineering that fits and lasts
Precision built from 304 stainless steel to exact specifications, the system uses factory hangers and mounting points for a proper, bolt-on axle-back fit. The black ceramic coated quad tips are laser engraved and sized perfectly to fill the rear valance for a purposeful look that resists heat discolouration.
