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 engine power as a priority, it produces a smooth and pleasant exhaust note at high RPMs.
We have made adjustments based on driving tests in various locations—including city streets, highways, hill climbs, and racetracks—and plan to release the product 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 light tuning that boosts power by 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.
