摘要： The inside of a muffler main body formed from an outer plate into the shape of a cylinder is divided into an upstream-side expansion chamber and downstream-side expansion chambers by partition walls. A catalyst is contained in the upstream-side expansion chamber having a larger volume, and a cylinder-shaped reinforcement member is attached to an inner surface of the outer plate of the upstream-side expansion chamber.

摘要： A muffler system can include an exhaust pipe configured to be connected to an exhaust port of an engine, and a muffler containing a catalyst. The muffler is configured to be connected to a downstream side of the exhaust pipe, and can include a first protector stay covering an upper surface of a high-temperature portion of the muffler. The first protector stay creates a front opening and a rear opening between an upper surface of the muffler and front and rear portions of the protector stay. A muffler protector is attached to the protector stay, the muffler protector being configured to cover an upper surface of the muffler.
