SFI SYSTEM


  1. FUNCTION


    1. Dual-stage exhaust control is used, which changes the exhaust gas flow passage depending on the driving conditions.

    2. This system controls the exhaust change valve according to motor operations to achieve quietness while the vehicle is driven normally and emphasize the exhaust sound when starting the engine and when the engine speed is high. Also, the exhaust change valve is opened at high engine speeds to reduce the back pressure.
