装置。 A muffler whose interior is divided into a plurality of chambers, an inlet main pipe connected to the muffler to guide exhaust gas from an engine to the muffler, and an outlet main pipe to discharge exhaust gas from the muffler. In the equipped exhaust pipe silencer, the inlet pipe branched from the main inlet pipe is connected to the silencer, the outlet pipe for discharging exhaust gas from the silencer is connected to the silencer separately from the main outlet pipe, and the inlet pipe is connected to the silencer separately from the main outlet pipe. Exhaust gas flow is connected to either the pipe or the inlet pipe.
A first valve is provided to shut off the flow of exhaust gas, and either the main outlet pipe or the outlet pipe is connected to the flow of exhaust gas.
An exhaust pipe muffling device characterized in that it is provided with a second valve that shuts off, and a valve opening/closing device that opens or closes the first valve or the second valve according to the selection of a driver or the like.
