Title: Manifold system

Abstract: A manifold system for a multi-cylinder internal combustion engine. The manifold system includes intake and exhaust manifolds having a common wall forming the bottom of a heat riser. Within the exhaust manifold dual walled liner construction is installed to provide a reaction chamber jacketed by a fluid jacket in a manner that gas discharged from the reaction chamber is directed toward a heater wall disposed adjacent the common wall and then flows through the jacket chamber. The jacket chamber conveys the gas out of the exhaust manifold to an exhaust pipe.
