An exhaust port of the engine and an inlet of expansion chamber are connected by an exhaust pipe, and the inlet of expansion chamber and an outlet of exhaust pipe are connected by a fitting with thermal durability and flexibility. In the case where the expansion chamber is followed by a muffler, at least a latter half of the expansion chamber is inserted into the muffler.
