Fi EXHAUST BMW M3/M4 G80/G81/G82 Cat-back Center Exit + Carbon Diffuser


Sport exhaust system by Fi EXHAUST dedicated to BMW M3/M4 G80/G81/G82.

The entire system is made of T304 stainless steel and finished with 4 tips in a central layout.

The system is compatible with both non-OPF and with OPF versions.


The Fi EXHAUST system has been designed using Valvetronic technology to control airflow, sound volume, and to increase overall performance and torque.

When the valves are closed, the system provides a comfortable ride. However, when the valves are fully open, an intense and sporty soundtrack is created.

Switching between sound profiles can be done using the factory drive mode change button or the optional Fi EXHAUST remote and mobile app.
