Abstract:
1. A combustion engine exhaust assembly for an automobile comprising: a cast metal manifold which is optionally coupled to a separate turbocharger, said manifold including multiple runners which converge to form a manifold outlet portion defining an internal exhaust gas passageway which is cast as part of said manifold and into which exhaust gas is collected, said passageway including a slot formed in the outlet portion along said exhaust gas passageway; and an axially disposed divider plate inserted into said slot and extending across said passageway to segregate the exhaust gas into at least two separate gas flow paths as it exits the manifold outlet portion; wherein said divider plate is formed from a material which differs from said manifold such that it is capable of elastic deformation during rapid heating of the exhaust manifold; and said divider plate is inserted into the slot formed in said outlet portion.
