This exhaust system is specifically designed for the B48D engine in the Z4 20i M-SPORT.
It was developed to minimize exhaust resistance as much as possible, enabling high performance at elevated engine speeds. It is also compatible with engine tuning.
The exhaust flap actuator utilizes BMW parts, so the exhaust flaps operate identically to BMW's system.

The exhaust sound is designed to deliver a pleasant tone from the driver's seat.
The exhaust finisher is available only in titanium anodized type.
The finisher tip glows purple in light-and-shadow contrast, while the sides appear as shadowed, deep black-purple.
