Abstract: An exhaust system for a combustion engine which comprises at least one exhaust manifold with a plurality of inlet pipes for connection to exhaust ports of the combustion engine. The exhaust system comprises a collector device for merging of the inlet pipes, which has one outlet opening. The outlet opening is connected to subsequent elements of the exhaust system, such as catalytic converter housing. The catalytic converter inflow pipe is guided up to just before the catalytic converter; and the catalytic converter housing is connected directly to the collector housing via a pipe surrounding the catalytic converter inflow pipe. The collector device is made as a one-piece collector housing of a material stiff in bending.

Abstract: An exhaust gas purification system, in particular for motor vehicles, having at least one catalyst body (6) which is arranged in a housing (1) and which has an in particular honeycomb-like metal matrix (8) as a substratefor the active catalyst material and a jacket (10), also made of metal, surrounding the matrix (8) and attached thereto in particular by soldering, via which the catalyst body (6) is fixedly connected, in particular welded, to the housing (1), wherein the catalyst body (6) is only fixedly connected to the housing (1) at one point (16), in particular at its downstream end region
