A muffler including a long outlet pipe having an exhaust gas inlet pipe portion , a return pipe portion , an exhaust gas outlet pipe portion , and two turnaround pipes for connecting the three pipe portions together in series. These pipe portions are arranged in parallel with one another along a longitudinal direction of a shell , and in such a manner that longitudinal axes L, L, L of the pipe portions are positioned at respective vertices of a triangle.

Muffler for an engine

In a partition wall arrangement for an exhaust gas pipe section including a partition wall including a main plate member separating the pipe section into two longitudinal passages, a reinforcing plate member is placed over and attached to a major surface of the partition wall member in a part adjacent to the upstream edge of the main plate member so that an improved durability is achieved through elimination of membrane vibrations. By providing an edge cover on the upstream edge of the partition wall, the partition wall can be protected from the adverse influences of the heat from the exhaust gas, and is reinforced even further.
