Abstract
A method for production of an exhaust-gas routing device that has a housing, an elongated substrate, and a compensating element, includes the following steps. At least one parameter of the substrate and/or of the compensating element is determined A target parameter, which describes a variable linked to a target geometry of the housing, is determined based on the measured parameter of the substrate and/or of the compensating element. The substrate and the compensating element are arranged in the housing, and the housing is deformed with an overpressure factor which is determined on the basis of at least one previous deformation of a previously manufactured device. The housing is measured after the deformation, and the thus-established values are compared with the target parameter. An overpressure factor for the deformation of a subsequently manufactured device is adapted if a deviation from the target parameter is detected upon measuring which lies above a defined threshold value.
