The HKS 3SX is a digitally controlled 3x Stage Exhaust system for the Nissan R35 GT-R.
It's always challenge to acquire both quietness and high output for automobile. To comply for turbo upgraded for R35 GT-R, we have developed changeover valve system muffler. So depending on the exhaust flow, the flow channel can be changed to give more power and cool exhaust sound.
This HKS exhaust system has 2 valves in front and 2 valves in the back operated by electric motor, the valves are connected to the motor with cables and special electronic unit controls the motor.
In the automatic mode, the valves are opened or closed by the RPM or automobile speed. For low RPM (Setting/Stage 1), all the valves are closed which provides quiet sound. For mid RPM (Setting/Stage 2), only the back valves are open for both power and quietness is provided. And finally for high RPM (Setting/Stage 3), all the valves are open for the most power. Also the manual mode let you open all the valves.
