ABSTRACT:
An exhaust emission control device is manufactured by sizing a housing of over a substrate and intumescent mat subsequently to heating said emission control device. The step of heating causes said intumescent mat to at least reach a temperature at which it swells. If the substrate has a washcoat layer, it may be left unfired until after it is assembled with the housing, in which case the step of heating causes the washcoat layer to sinter.
