Abstract

A catalytic converter for purifying exhaust gases from an internal combustion engine includes a monolithic ceramic substrate having a peripheral surface encircled by a non-intumescent supporting mat material. A metal shell comprising a wider portion which is adjacent to and encloses the mat material and the substrate. The metal shell further comprises a narrower portion which overlaps and is attached to the outer surface of the wider metal shell portion. The wider and narrower metal shell portions combine to exert a compressive force on the wrapped substrate.
