A manifold converter apparatus comprising a manifold housing including a plurality of inlets wherein each inlet of the plurality of inlets is mounted immediately adjacent an internal combustion engine exhaust port and a plurality of lead pipes wherein each lead pipe of the plurality of lead pipes provides an exhaust gas flow passage between one of the inlets and a manifold plenum and at least one catalyst coated substrate located within at least one of the inlets between at least one of the exhaust ports and one of the lead pipes. An advantage achieved includes quick light-off of the manifold converter apparatus after cold start of the vehicle engine.
