Abstract
A catalytic converter apparatus includes a housing having a chamber, an inlet for receiving gas, and an outlet for exhausting gas. The apparatus further includes a catalytic brick positioned within the chamber for purifying the gas and a support mat disposed between the housing and the brick for supporting the brick with respect to the housing. The support mat has a leading edge located adjacent the inlet of the housing. The improvement includes a barrier strip attached to the leading edge of the support mat for protecting the leading edge from excessive wear resulting from the flow of gas over the leading edge of the mat.
