ABSTRACT:
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.
