Zusammenfassung:The invention relates to a device for the catalytic treatment of exhaust gases of motor vehicles which comprises a catalyst substrate designed as a hollow cylinder, an inlet-side and an outlet-side gas baffle and an outer wall, wherein the gas baffles enclose the catalyst substrate and the outlet-side gas baffle and the catalyst substrate form a first cavity into which an exhaust-gas stream can be fed, passing through the catalyst substrate and entering a second cavity which is surrounded by outer wall, gas baffles and catalyst substrate, wherein the outlet-side gas baffle has gas vents, and wherein the recessed part of the outlet-side gas baffle is beaded, with the result that the catalyst substrate is fixed. The invention also relates to a process for the production of the device according to the invention and its use, plus a method for cleaning exhaust gases of motor vehicles.
