Abstract: An exhaust device for an engine includes an engine main body having a cylinder head provided with a manifold exhaust passage formed with a gathering exhaust port, a turbo supercharger, a catalyst device provided adjacent to the turbo supercharger, and a processing device disposed on the same side as the cylinder head surface of the engine main body. The processing device includes an exhaust gas processing device and an EGR device. The turbo supercharger guides exhaust gas discharged from the gathering exhaust port upward. The catalyst device includes a carrier, and a container which allows the exhaust gas to pass through a lower region of the carrier. The EGR device and the exhaust gas processing device are at least disposed below the catalyst device.
