を特徴とするデユアル型排気管。 The exhaust pipe has exhaust branch pipes provided in parallel with each other and an exhaust manifold pipe to which one end of each of the two exhaust manifold pipes is connected, and a connection part between the two exhaust manifold pipes and the exhaust manifold pipe. In a dual-type exhaust pipe for a multi-cylinder internal combustion engine, which has a Y-shape, each of the two exhaust branch pipes has its connection end to the exhaust manifold pipe obliquely removed at the mutual joint side. The two exhaust branch pipes are connected to each other through openings formed by the removal, and the openings are approximately U-shaped when viewed from the removed surface, and extend in a direction perpendicular to the axial direction of the two exhaust branch pipes at their respective meeting points. A dual exhaust pipe characterized in that it includes an extending straight edge.
