Abstract:
1. An apparatus for treating an engine exhaust stream comprising: an exhaust manifold; at least one catalytic converter element insertable in said exhaust manifold through an insert opening in said exhaust manifold; a cover positionable on said insert opening for closing said insert opening; and said cover including a stabilizer, wherein, when said catalytic converter element is inserted into said exhaust manifold and said cover is positioned on said insert opening, said stabilizer will be received on an outer end portion of said catalytic converter element in a manner effective for at least restricting movement of said catalytic converter element in said exhaust manifold and said apparatus further comprises at least one contacting strip attached to said outer end portion of said catalytic converter element such that said stabilizer will contact said contacting strip in a manner effective for providing increased frictional resistance between said stabilizer and said outer end portion of said catalytic converter element.
