Fi Exhaust Catless Downpipe | Mercedes Benz W205 C63 C63s AMG 2015-2022

Mercedes-Benz AMG W205 C63 S 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. 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 Mercedes-AMG W205 C63 S is achieved through individually designed muffler internals that are fabricated to offer an ultimate driving experience.
