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.
