A catalytic converter structure is provided for purifying exhaust gases from an internal combustion engine. The catalytic converter structure includes a cylindrical catalyst substrate; a first cylindrical tube covering a first end of the substrate; a second cylindrical tube covering a second end of the substrate; a support mat surrounding a central portion of the substrate and portions of the first and second cylindrical tubes; and a cylindrical housing within which the substrate, first and second cylindrical tubes and the support mat are located. The structure requires few components, is easy to tool and easy to adapt to different engine implementations.
