Exhaust manifold and engine

The embodiment of the utility model discloses an exhaust manifold and an engine. The exhaust manifold comprises a plurality of exhaust pipes, a ternary catalyzing apparatus, an intake flange, an exhaust flange and a bracket, wherein one end of the bracket is connected with the exhaust flange, the other end of the bracket is fixed to an air cylinder body, the intake ends of the multiple exhaust pipes are connected with the intake flange, the exhaust ends of the multiple exhaust pipes and the intake end of the ternary catalyzing apparatus are integrated, and the exhaust end of the ternary catalyzing apparatus is connected with the exhaust flange. Because the intake flange and the cylinder body are connected through the bracket according to the exhaust manifold, the vibration resistance and the reliability of the exhaust manifold can be effectively enhanced; the ternary catalyzing apparatus is directly integrated on the intake flange and the exhaust flange, the ternary catalyzing apparatus is connected with the
