Abstract
An exhaust system for an engine comprises a cylinder head having an integral exhaust manifold to collect exhaust gas exiting the engine combustion chambers. An exhaust gas conduit in fluid communication with the exhaust manifold comprises an inlet end connected to the cylinder head, a portion that extends towards an upper end of the internal combustion engine and an outlet end configured to define an inlet end of a multistage catalytic converter. The catalytic converter comprises a canister having an inlet end located adjacent the top of the engine and includes first and second catalyst substrates and a collector closing an outlet end of the canister. The outlet end of the canister is located adjacent to the bottom of the engine, and the first and the second catalyst substrates receive and convert constituents of exhaust gas passing from the inlet end of the canister to the outlet end.
