Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent the deformation or damage of an upstream section of the partition plate arranged in an inner pipe due to thermal stress in an upstream end section of a two-passage type exhaust pipe connected to an exhaust manifold. SOLUTION: Two passages are formed by arranging the partition plate 4 in the diameter direction in the inner pipe 2, and a holding section 8 whose diameter is slightly reduced is formed at the downstream side of the end section of an outer pipe 3. The outer pipe 3 is fitted to the inner pipe 2, and the holding section 8 is fixed to the outer pipe 3, and a flange 6 is fixed to an end section of the outer pipe 3 to be connected to the exhaust manifold. Since clearance 5a is formed on the upstream side of the inner pipe 2, even if the partition plate 4 is lengthened due to thermal expansion, the end section at the upstream side of the inner pipe 2 is not restrained. This eliminates the cause of stress.
