The exhaust control system (excs) consists of the exhaust control valve (excv), exhaust control valve actuator (excva) and exhaust control valve cables (excv cables).
Excv is installed in the exhaust pipe. Excva is mounted inside of the right frame. The excv is operated by the excva via the cables. This system is designed to improve the engine torque at low engine rpm.
