An exhaust gas muffler for an internal combustion engine has a housing having an inlet and an outlet for engine exhaust gas. The housing has walls defining the interior of the housing. The housing has a first housing shell having a first connecting flange and a second housing shell having a second connecting flange, wherein the first and second connecting flanges are fastened to one another in a common flange plane. Each housing shell has a bottom. A partition is mounted in the housing and divides the interior of the housing into two compartments. The two compartments are connected by flow connections allowing passage of the engine exhaust gas between the two compartments. The partition has opposed ends supported respectively on the bottoms of the housing shells. The partition has two wall portions curved outwardly in opposite directions relative to a plane of the partition and has multiple openings. The wall portions define a damping element positioned in a flow path of the engine exhaust gas from the inlet to the outlet. Multiple openings allow passage of the engine exhaust gas therethrough. The wall portions have edges that are connected to the inlet and delimit a flow cross-section of the inlet. |
