BMW F40 M135iX 2.0T B48A20 2019-2020 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 from 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, or optional FI Exhaust remote control and mobile App.

The unique sound and performance for BMW F40 M135i is achieved through individually designed muffler internals that are fabricated to offer an ultimate driving experience.
