A muffler is disclosed that includes a housing, an inlet pipe, an outlet pipe, a first partition with first apertures, and a second partition with second apertures. The first partition and housing define a first chamber with which the inlet pipe communicates. The second partition and housing define a second chamber with which the outlet pipe communicates. The second partition is spaced from the first partition to define an intermediate chamber. The muffler also includes a sound absorbing member encapsulated within the intermediate chamber. Exhaust noise entering through the inlet pipe enters the first chamber, moves through the first apertures into the intermediate chamber, moves through the second apertures into the second chamber, and exits through the outlet pipe. Exhaust noise is reduced when passing through the sound absorbing member. |
