Claims

[Scope of utility model registration request]

The dual exhaust manifold has a number of branch pipes corresponding to the number of cylinders of the engine, and the downstream side of each branch pipe is grouped into two groups, each forming a first exhaust passage and a second exhaust passage. , in the exhaust gas outlet portion of the dual exhaust manifold, the first exhaust gas is attached to a partition wall that partitions the first exhaust passage and the second exhaust passage by a predetermined length from the end face of the outlet portion. A dual exhaust manifold characterized in that a slit is provided that communicates the passage with the second exhaust passage.
