ABSTRACT:
The invention is directed to a method for producing a device forming a muffler 1 or a catalytic converter comprising a casing having an outer wall part 4 and an inner wall part 5. The two wall parts 4, 5 are connected with one another at least at the ends of the casing and are constructed in such a way that there is an intermediate space 16 between them at least in some places. This intermediate space 16 is produced in that a pressure is generated between the inner wall part 5 and the outer wall part 4 by a substance in order to bend one wall part 4, 5 away from the other wall part 4, 5 at least in some places.
