It has two inlet pipes, one inlet pipe is connected to the outlet pipe on the front side of the muffler via a valve, the other inlet pipe is connected inside the muffler, and the valve is connected to the outlet pipe on the front side of the muffler. In a variable muffler configured to switch and use one or two inlet pipes, the inside of the muffler is partitioned by a double plate to form a resonator chamber, an expansion chamber, a resonator chamber, and a resonator chamber from the front side. At the same time, the tail-side resonator chamber forms a double resonator chamber, and an outlet pipe connected to the inlet pipe via a valve penetrates from the front side to the tail side, and connects the expansion chamber and the front-side resonator of the double resonator chamber. A variable muffler characterized by being composed of a double pipe with small holes in the chamber and the inside.
