Claims

[Scope of Claim for Utility Model Registration] 1. In an engine exhaust system in which two exhaust pipes are brought together and connected to a silencer, a part where the two exhaust pipes come together is located approximately at the center of the part where the two exhaust pipes come together. A main partition plate is provided that extends along the central axis of the main partition plate and has a communication hole, and
2 above on both sides of the main partition plate in the gathering part
An exhaust system for an engine, characterized in that two sub-partition plates are provided at positions facing each exhaust pipe, the sub-partition plates extending substantially parallel to the main partition plate and each having a communication hole. 2. In an engine exhaust system in which two exhaust pipes are assembled and connected to a muffler, there is a main pipe extending approximately at the center of the joining part of the two exhaust pipes and extending approximately along the central axis of this joining part. A partition plate is provided, and two sub-partition plates extending substantially parallel to the main partition plate are provided on both sides of the main partition plate in the gathering part at positions facing the two exhaust pipes, respectively. Also, an engine exhaust system characterized in that the rear end position of the main partition plate and the rear end positions of the two sub-partition plates are staggered.
