Note
- Because this is a 4-finisher system, installation requires the BMW 5112 8089 721 rear diffuser.
- For non-M-SPORT vehicles, the M-SPORT rear bumper trim is also required.
- 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.
The exhaust flap actuator utilizes BMW parts, so the exhaust flaps operate identically to those in BMW vehicles.

The exhaust sound is designed to provide a pleasant tone that can be enjoyed 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, creating a deep black-purple appearance.
