An automobile exhaust gas muffler construction for flowing exhaust gases, comprises a housing having spaced apart semi-cylindrical end walls interconnected by tangential straight side walls. The housing also includes a front wall having a tubular inlet extending therethrough and through at least a portion of the housing, and a rear wall with a tubular outlet extending through the rear wall and through at least a portion of the housing. The tubular inlet and tubular outlet each have a gas flow slot passage defined along its length within the housing and gases flow from the inlet through this slot in the housing and through spiral passages defined by sound-muffling walls. The spiral passages of the inlet communicate with an expansion chamber defined in the housing which, in turn, communicates with spiral passages defined around the outlet connection. |
