Abstract
An improved apparatus for withstanding the high temperatures in the exhaust assembly of an internal combustion engine. A quilted insulating element is extended about a liner of a manifold or port liner. The liner in this invention is preferably ceramic. After assembling the insulating element about the liner, a metallic ring is installed for support during casting. A metallic housing, preferably cast iron, can then be cast around the liner, insulating element, and metallic ring.
