ABSTRACT:
A catalytic exhaust treatment device for an automotive vehicle includes a generally cylindrical substrate having a support seal at either end and with each of the support seals encircling an end of the substrate, and an intumescent mat applied to the cylindrical surface of the substrate, with the mat extending between the support seals. The catalyst further includes a cylindrical container having an inside diameter sized so as to compress the support seals and the mat such that the seals and mat are maintained in contact with the substrate and the container.
