The digital control valve exhaust system for sound pressure and exhaust efficiency. It's always a challenge to acquire both quietness and high output for the automobile. To comply for turbo upgraded for R35 GT-R, we have developed a changeover valve system muffler. So depending on the exhaust flow, the flow channel can be changed to give more power and cool exhaust sound.

2 valves in front and 2 valves in the back operated by an electric motor. The valves are connected to the motor with cables and a special unit controls the motor.

In the automatic mode, the valves are opened or closed by the RPM or automobile speed. For low RPM (Stage 1), all the valves are closed which provides quiet sound. For mid RPM (Stage 2), only the back valves are open for both power and quietness is provided. And finally, for high RPM (Stage 3), all the valves are open for the most power. Also, the manual mode lets you open all the valves.

The finisher has a special surface work that makes it hard for soot to stick to.

This graph shows each 3 stages testing. We have analyzed the muffler's sound pressure and exhaust balance and set the switching point of the stages. (When driving, it automatically changes)
