Audi B9 S5 (Non Sport Diff Vehicles Only) 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.

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 Audi B9 S5 is achieved through individually designed muffler internals that are fabricated to offer an ultimate driving experience.
