An engine includes a cylinder block including a plurality of cylinders, an exhaust manifold, and an exhaust pipe. The exhaust manifold includes a first passage and a second passage. The first passage includes a plurality of first inflow ports into which exhaust gases flow from the plurality of cylinders, a first collecting portion that collects exhaust gases that have flowed into the plurality of first inflow ports, and a first exhaust port through which exhaust gases collected by the first collecting portion are discharged. The second passage includes a second inflow port into which exhaust gases flow and a second exhaust port through which exhaust gases that have flowed into the second inflow port are discharged. The exhaust pipe includes a connection passage through which the first exhaust port and the second inflow port are connected together.
