<p>An exhaust manifold comprises branch pipes (2 to 5), the exhaust gas upstream side ends of which are connected to a head flange (1) and the overall lengths of which are different from each other; and a collection part (6) for collectively receiving the exhaust gas downstream side ends (2a to 5a) of the branch pipes (2 to 5). A linear straight pipe part (11) is formed at a substantially center of at least the branch pipe (2) having the longest overall length among the branch pipes (2 to 5), and a thermally deformable bellows-like absorption part (12) is provided in the straight pipe part (11).</p> |
