1. A method of assembly a catalytic converter of the motor vehicle type which comprises preassembling an annular gas impervious shock absorbent support mat only around the mid-section of a catalyst substrate to form a preassembly, inserting the preassembly into a tubular body of metal so as to be in centered, spaced, relation to the interior wall of said body, radially deforming the wall of the metal body into a reduced diameter annular ring in radial contact with said annular mat, said deforming step substantially simultaneously applying uniform inward radial pressure on said mat and radially compressing he mat to substantially reduce its thickness and to apply sufficient radial pressure against the substrate to hold the substrate in the body.
