Claim:
1. A method of joining a component and an exhaust manifold of an internal combustion engine at a first joint and a second joint wherein the first joint is between the component and the exhaust manifold and the second joint is between the component and a surface of at least one fastener, comprising pre-connecting a first joint insert and a second joint insert by a metal sheet connector to provide a one-piece joint insert unit, placing the first joint insert of the joint insert unit at the first joint between the component and the exhaust manifold, placing the second joint insert of the joint insert unit at the second joint, said first joint insert and said second joint insert each having a first metal sheet layer and a separate second metal sheet layer that are relatively slidable and are joined together by at least one connecting arrangement that permits relative sliding movement between the first metal sheet layer and the second metal sheet layer in response to thermally-generated stress at at least one of the first joint and the second joint during operation of the internal combustion engine, and fastening the component and the exhaust manifold together at the first joint and the second joint using said at least one fastener received in a respective fastener-receiving opening in the first metal sheet layer and in the second metal sheet layer of the first joint insert and of the second joint insert.
