Zusammenfassung:	According to the present invention, an exhaust manifold comprises: a plurality of runners formed to have a circular shape having a circular inlet end and a circular outlet end to enable the inlet end to be connected to each cylinder of an engine; and a diffuser having one diffuser outlet and a plurality of diffuser inlets where each inlet end of the runners are connected. According to the present invention, exhaust gas introduced to the runner can smoothly flow to the diffuser without a noise and vibration, and the flow speed of the exhaust gas flowing through each runner can be uniform. Moreover, airtightness and durability of a portion where the runner and the diffuser are coupled are improved. 본 발명에 의한 배기 매니폴드는, 원형의 입구단과 출구단을 구비하는 원형관 형상으로 형성되어 엔진의 각 실린더에 입구단이 연결되는 복수 개의 런너와, 상기 복수 개의 런너 입구단이 각각 연결되는 복수 개의 디퓨저입구와 하나의 디퓨저출구를 구비하는 디퓨저를 포함하여 구성된다. 본 발명에 의한 배기 매니폴드는, 런너로 유입된 배기가스가 소음 및 진동 발생 없이 원활하게 디퓨저로 흐를 수 있고, 각 런너를 통해 흐르는 배기가스의 유속을 일정하게 할 수 있으며, 런너와 디퓨저 간의 결합부위 밀폐성 및 내구성이 향상된다는 장점이 있다.
