Fi EXHAUST - BMW Z4 G29 20i / 30i OPF - OPF valved cat-back with two silver tips

This OPF version of the Fi EXHAUST system is for BMW Z4 G29 20i/30i cars with the B48 engine and particulate filter. It uses the distinct BN-G29B48F-CBE code, dual silver tips and valve cable. The F suffix separates it from the non-OPF system for the same chassis.

The configuration lists the cat-back system, two TIP63114S silver tips and CAB-BTB. The tips are silver, and no separate remote appears in the package line. For an imported car or one modified after production, confirm OPF presence and the original valve motor by VIN before choosing this version.

Valves and sound

Fi uses a valved layout to adjust sound volume for different driving situations. With the valves closed, flow is routed through the muffler; opening them makes the exhaust more pronounced. Actual control depends on the Z4’s factory electronics. This configuration does not list a separate Fi Pro system unless purchased separately.

The price-list configuration retains factory valve control or does not list a separate remote. Do not assume remote or app functionality; it must be confirmed by the code of the specific control module.

Fitment

Listed application: BMW Z4 G29 20i / 30i OPF, 2019+; Chassis G29; 2.0T B48 engine; OPF equipped. These details matter more than a similar model name: a generation, engine or filter change may require another part number. Confirm factory specification by VIN before pre-ordering.

Do not use this position for a non-OPF G29; the price list carries a separate BN-G29B48-CBE system for that car. Before installation, confirm engine, year, chassis and factory valve control. The image represents the same model family; the SKU in this listing identifies the OPF configuration.
