Exhaust Prototype: G29/Z4-B48 Engine
This is the exhaust system from behind the catalytic converter to the tailpipes.
The exhaust flap is installed by relocating the genuine BMW actuator.
Using the M40i rear diffuser, the quad-exit tail pipes emphasize a sporty look.
Designed with a focus on engine power, 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.
