Works with any brand exhaust even the factory stock M4 system.
This stunning carbon-fiber diffuser is offered as an option with the choice of a high-gloss or matte finish.
It is a completely new design from the one that comes as standard on the car, and it gives the rear of your M4 a more aggressive, and sporty feel.
It will really emphasize your larger diameter, carbon fiber or titanium Akrapovic exhaust tips.
