Abstract

A monolithic exhaust gas catalyst, or catalytic converter, is arranged in a metallic housing and is supported against the inner surfaces of the housing by a resilient fiber material positioned therebetween. The resilient fiber material is provided with a catalytically active coating so that the exhaust gases which flow outside the exhaust gas catalyst and through the fiber material, are also converted by the treated fiber material.
