ABSTRACT:
A water-jacketed exhaust manifold for a multi-cylinder internal combustion engine has a plurality of inlet ports which are connected via a cavity in the manifold to an outlet port formed in a face of the manifold. At least one septum member is disposed in the manifold to subdivide the cavity into at least two chambers with each of which are associated at least two inlet ports. Each septum extends in the outlet port to the manifold outlet face. A water-jacketed header pipe is connectible to the manifold face. A gas flow passage in the header pipe is subdivided by at least one septum over the length of the passage. Each header pipe septum is arranged to substantially align with and register with a corresponding manifold septum upon connection of the header pipe to the manifold.
