Abstract

An exhaust gas system includes an exhaust manifold, in particular a single-wall exhaust manifold, which includes a plurality of inlet pipes for connection to exhaust gas outlets of an internal combustion engine and a collector device for the combining of the inlet pipes. The collector device has an outlet opening which is connected to downstream elements of the exhaust gas system, wherein the collector device is resistant to bending and the inlet pipes are comparatively flexible with respect to the collector device. The collector device includes an inlet pipe stub which is likewise resistant to bending and which is made for the direct connection to an exhaust gas outlet of an internal combustion engine.
