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 of 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 E60 M5 is achieved through individually designed muffler internals that are fabricated to offer an ultimate driving experience.
