BMW G8x M3/M4 (Competition) Fi Exhaust (Frequency Intelligent Exhaust) high-performance valvetronic exhaust system is direct replacement bolt on system manufactured out of a high-grade T304 stainless steel that offers an exhilarating soundtrack.

The Fi EXHAUST system is designed with a valvetronic technology to control airflow, sound volume and enhance the overall performance and torque. On average horsepower is expected to increase 5-10% after installing a full catless system, which includes a valvetronic catback and ultra-high flow downpipe.

When valves are closed exhaust gasses are routed through the muffler resulting in a low-profile comfortable drive. However, when the valves are fully open an intense and sporty soundtrack is produced.

Switching between street and race sound profiles can be done using factory exhaust/sport button or drive mode.

The unique sound and performance for BMW G80 M3 / Competition is achieved through individually designed muffler internals that are fabricated to offer an ultimate driving experience.
