Exhaust system with conduit element

The invention relates to an internal combustion engine (1), especially a flexible conduit element (14) for an exhaust system (4) of an internal combustion engine of a motor vehicle. The flexible conduit element (14) includes a metal bellows (15) which is corrugated in a ring-shaped or helical pattern and through which an exhaust gas stream (8) can flow. The risk of deposition of urea and/or urea derivatives in the metal bellows (15) is reduced by a conical flow guide body (16), through which the exhaust gas stream (8) can flow, and which tapers in the direction of flow of the exhaust gas stream (8) and which protrudes into an inlet area (17) of the metal bellows (15). The flexible conduit element (14) of the invention is combined with the flow guide body (16) integrated therein.
