The present invention relates to a soundproof exhaust manifold of a high-speed boat. The soundproof exhaust manifold is coupled with the bottom end of an engine for supplying driving force for propelling a high-speed boat, and reduces a noise of an exhaust manifold for discharging an exhaust gas. The soundproof exhaust manifold comprises: a manifold housing including an exhaust gas feeding unit formed at the top thereof to feed an exhaust gas generated from the engine, a cooling water feeding unit formed in the side surface thereof, and an exhaust gas discharging unit formed at the bottom thereof; and a silencer coupled with the end of the exhaust gas feeding unit by including at least one silencer hole formed in the outside of the side surface thereof, a silencer exhaust gas discharging unit formed at the bottom thereof, and a cylindrical silencer housing having a metal chip formed therein. First noise reduction is performed by reducing temperature of an exhaust gas through cooling water, and second noise reduction is performed through the silencer. Noise caused by an exhaust gas generated from the engine can be remarkably reduced.

    본 발명은 고속정의 추진을 위한 구동력을 공급하는 엔진 하단에 결합하며 배기가스를 배출하는 배기 매니폴더의 소음을 감음시키는 고속정의 감음형 배기 매니폴더에 관한 것으로 상부에 엔진에서 발생하는 배기가스가 유입되는 배기가스 유입부와 측면에 냉각수 투입부가 구비되며 하부에 배기가스 배출부가 구비되는 매니폴더 하우징과 측면 외부에 적어도 하나 이상의 소음기 홀과 하부에 소음기 배기가스 배출부 및 내부에 금속칩이 구비되는 원통형의 소음기 하우징으로 구성되어 상기의 배기가스 유입부 말단에 결합하는 소음기로 구성되어 냉각수를 통하여 배기가스의 온도를 낮추어 1차 감음하며, 소음기를 통하여 2차 감음하여 엔진에서 발생하는 배기가스로 인한 소음을 현저하게 줄일 수 있는 효과가 있다.
