Abstract
The present disclosure considers an exhaust manifold and method of casting an exhaust manifold, where the exhaust manifold has both a portion of the exterior wall that is jacket cooled and a portion of the exterior wall that is not cooled. The non-cooled portion of the exterior is not accessible when the exhaust manifold is secured to the engine block. Furthermore, the non-cooled portion of the exterior wall of the exhaust manifold is designed to add stability during the casting process and allow for a simplified casting process with fewer cores.
