An exhaust gas muffler of multi-chamber construction includes an outer housing having an upper and lower half shell, an inner shell, and an inner exhaust gas duct through the exhaust gas muffler. The inner exhaust gas duct has at lease one curved outlet pipe that has a first curved section and a straight outlet end runs flush with the outer housing. The invention also covers a method for the production of the multi-chamber exhaust gas muffler.

Multiple-chambered exhaust muffler

In an exhaust housing part of a motor vehicle, particularly for an exhaust muffler or an exhaust gas catalyst of an automobile, with a sheet blank as a semi-finished part which, after a stamping process in a tool, forms an upper half shell or a lower half shell of a half-shell muffler or catalyst; or after a wrapping process in a tool, forms a wrapped exhaust gas funnel or cylinder, or an exhaust gas pipe connection; it is proposed to prefabricate the sheet blank as an integral, profiled sheet metal part of differing thickness, with at least one strip section of smaller thickness, and at least one strip section of greater thickness which locally reinforces the finished exhaust housing part (half shell, funnel, cylinder or pipe connection) at least in one wall region.

To prepare an absorption muffler for motor vehicles with a sound-absorbing material arranged in a hollow space of an exhaust muffler body in the form of glass wool (2), which is introduced into the hollow space in the form of an expanded, endless glass fiber roving, it is proposed that the exhaust muffler body (1) be completely prefabricated and assembled before the glass wool (2) is introduced into the prefabricated, assembled exhaust muffler body (1) from the outside.
