Abstract
A muffler for a two-stroke internal combustion engine has a housing enclosing a hollow space and having an exhaust gas inlet and an exhaust gas outlet. Shaped sheet metal members are mounted in the housing and define an exhaust gas flow channel. The flow channel extends at least over a portion of its length in a plane of the sheet metal members. A first one of the sheet metal members has a projecting portion projecting from the plane of the sheet metal members and forming a connector of the flow channel. The connector communicates with the exhaust gas inlet. A second one of the sheet metal members has a projecting portion projecting from the plane of the sheet metal members and forming an end portion of the flow channel opening into the hollow space of the housing.
