Abstract
A catalytic converter having two spaced catalyst elements is positioned between a front muffler and a rear muffler. Chrome plating of the mufflers does not adversely affect performance of the catalyst elements because welding of the mufflers to opposite ends of the catalytic converter is accomplished after the chrome plating step. Masking of the joinder areas before plating avoids blow holes at the welds, and silver paint is later applied to the areas which were masked. The catalytic converter is constructed by simultaneously pushing the two catalyst elements and flanged sleeves into opposite ends of the catalyst casing, using tapered guide rings and flanged pusher bars to squeeze peripheral cushions into place within the catalyst casing and around each of the catalyst elements. Welding electrodes are employed in combination with the flanged pusher bars to spot weld the catalyst casing to the flanged sleeves.
