Abstract
A catalytic converter with a one piece housing is made by inserting catalyst elements into opposite open ends of a sheet metal tube until their support mats abut against preformed annular ribs after which annular ribs are formed in the tube to engage the other ends of the support mats and the ends of the tube are pinched together to form sealed end closures with gas flow passages in them.
