Exhaust Prototype: G29/Z4-B48 Engine

This is the exhaust system from behind the catalytic converter to the tailpipes.
The exhaust flaps are installed by relocating the genuine BMW actuator.
Using a rear diffuser designed for the M40i, the quad-exit tailpipes emphasize a sporty look.
Designed with a focus on engine power, it produces a smooth and pleasant exhaust note at high RPMs.
We’ve made adjustments based on driving tests in a variety of locations—including city streets, highways, hill climbs, and racetracks—and plan to release it around December.

The G29/Z4-20i features a short wheelbase and a 4-cylinder turbocharged engine ( B48 ), resulting in a light front end and excellent handling. With a light tuning upgrade that adds about 100 horsepower, it transforms into a vehicle that offers an exceptional motorsports experience.
We want you to experience this excitement, so we’ve started developing an exhaust system for the 4-cylinder model.
