マフラ構造。 In a muffler structure where the inside of the shell is partitioned by multiple partition walls and equipped with a pre-muffler outlet pipe to guide a portion of the introduced exhaust gas to the pre-muffler, the inside of the shell is equipped with an inlet pipe that divides the exhaust gas discharged from the engine into two systems. One of the inlet pipes forms a first flow path that directly leads exhaust gas to the final stage expansion chamber via a switching valve, and the other inlet pipe forms a first flow path that leads exhaust gas directly to the first stage expansion chamber. After introducing the gas, the resonance chamber, the expansion chambers of each stage, and A muffler structure characterized in that a second flow path is formed to guide exhaust gas to the pre-muffler outlet pipe.
