Exhaust housing

Abstract

The disclosure relates to a gas-carrying exhaust gas housing of an internal combustion engine comprising: a manifold section, having a central axis and multiple manifold pipe connectors, for securing on a flange plate for connecting to a cylinder of an internal combustion engine; a catalyst housing section having a central axis; and an exhaust pipe connector section provided downstream of the catalyst housing section, for connecting to an onward-conveying exhaust system. In addition, together with catalyst housing section and exhaust pipe connector section, the manifold section forms a two-shell exhaust housing having a first half shell and a second half shell, wherein the two half shells have a separation plane (T) running parallel to the central axis at least in sections, wherein the manifold section has multiple integral manifold pipe connectors which can be attached directly to a flange plate.
