Exhaust prototype G29/Z4-B48 engine

This is the exhaust system from the catalytic converter to the finisher.
The exhaust flap uses the relocated BMW genuine actuator.
Using the M40i rear diffuser, the finisher features a quad-exit design to emphasize a sporty image.
Designed with engine power in mind, it delivers a smooth and pleasant exhaust note at high RPMs.
Tuning was refined through driving tests in various locations—city streets, highways, hill climbs, and circuits—with a planned release around December.

The G29/Z4-20i features a short wheelbase and a 4-cylinder turbo engine ( B48 ), resulting in a light front end and excellent agility. With light tuning to boost power by around 100 horsepower, it transforms into a vehicle that delivers outstanding motorsport enjoyment.
We want you to experience this fun, so we've started developing an exhaust system for the 4-cylinder model.
