The utility model relates to an exhaust manifold with a new structure for a boosting engine. The exhaust manifold with the new structure for the boosting engine is formed by an exhaust manifold, an air outlet end flange, an air inlet end flange and three exhaust branch pipes; the air inlet end flange is connected with the air inlet of each exhaust branch pipe; all exhaust branch pipes are converged to the exhaust manifold; the air path of the exhaust manifold is round and is gradually reduced to the air outlet end flange. The exhaust manifold with the new structure for the boosting engine is compact in structure, reasonable in design, high in heat resistance and strength, space-saving and stable and reliable in work.
