Note
- Because this is a 4-finisher system, the BMW 5112 8089 721 rear diffuser is required for installation.
- Vehicles without M-SPORT also require the M-SPORT rear bumper trim.
- Cannot be installed on the M40i.

This exhaust system is specifically designed for the B48D engine in the Z4 20i M-SPORT.
It was developed to minimize exhaust backpressure as much as possible, enabling the engine to deliver peak performance at high RPMs. It is also compatible with engine tuning.
Since the exhaust flap actuator utilizes BMW parts, the exhaust flaps operate identically to those on BMW vehicles.

The exhaust sound is designed to provide a pleasant tone from the driver’s seat.
The exhaust finisher is available exclusively in anodized titanium.
Due to the contrast between light and shadow, the tip of the finisher glows purple, while the sides cast a shadow, giving it a deep black-purple appearance.
