FI Valvetronic Exhaust System for BMW G29 Z4 B48

The FI Valvetronic Exhaust System for BMW G29 Z4 B48 is an exquisite direct replacement manufactured from high-grade T304 stainless steel. Its advanced valvetronic technology allows smooth control of airflow, sound volume and improved overall performance and torque. HP gains of 5-10% typically result from a full catless system, which includes a valvetronic catback and ultra-high flow downpipe. When valves are closed, the exhaust gasses are routed through the muffler, creating a low-profile soundscape; when valves are open, a sporty and energetic soundtrack is produced. Switching between street and race profiles is achievable with the factory exhaust/sport button or optional Fi EXHAUST remote control/mobile App. Muffler internals are custom-designed to give an astonishing driving experience. Please note each part of the Fi EXHAUST system needs to be ordered separately and the actual product may differ in appearance based on car year and region. Product images
