Abstract
A first connection pipe, which penetrates a partition wall, and extends to a second expansion chamber side from inside a first expansion chamber, and a second connection pipe, which extends to an exhaust outlet side from the partition wall inside the second expansion chamber are provided; first outer periphery connection holes, which allow exhaust gas from an exhaust pipe to flow out to the second expansion chamber, are formed in the outer peripheral surface of the first connection pipe; second outer periphery connection holes which allow the exhaust gas having flowed out to the second expansion chamber through the first outer periphery connection holes to flow into the second connection pipe, are formed in the outer peripheral surface of the second connection pipe; the first connection pipe and the second connection pipe are arranged such that they are partially parallel to each other; and the first outer periphery connection holes are arranged closer to the exhaust outlet side than the second outer periphery connection holes.
