Designed to make the X4 M / X4 M Competition stand out from the crowd even more, the visual delight of Akrapovic exhaust systems can be further enhanced with the addition of an optional, ABE type-approved carbon fibre rear diffuser. It's beautifully handcrafted from the finest materials and is designed to enhance the exclusive look of the carbon tailpipes. Available in high gloss finish.

Warning: Cannot fit with genuine trailer tow hitch. With Akrapovic diffuser, hands-free trunk-lid opening/closing sensor is not working.
