Applicable Models
BMW G29/Z4-20i M-SPORT
NOTE
- Due to the 4-finisher, a BMW 5112 8089 721 rear diffuser is required for installation.

This exhaust is exclusively designed for the B48D engine Z4 20i M-SPORT.
It has been developed to minimize exhaust resistance as much as possible, and to achieve performance at high engine speeds. It also supports engine tuning again.
The exhaust flap actuator uses BMW parts, so the exhaust flap moves the same as BMW.

The exhaust sound is designed so that the driver can enjoy a pleasant tone in the driver's seat.
The exhaust finisher is only titanium anodized type.
The light and shadow contrast makes the finisher tip glow purple, while the sides are in shadow and appear deep black-purple.
