An assembly unit 1 of an exhaust system has at least one and particularly two connection funnels 2 made of cast material and a pipe 3. The at least one connection funnel 2 has a pipe socket 21 and at least one bracket 22. The bracket 22 is arranged outside of the pipe socket 21. A connection section 31 of the pipe 3 is fastened to the bracket 22 of the at least one connection funnel. The pipe socket 21 extends beyond the connection section 31 of the pipe 3 into the interior of the pipe 3 and is spaced apart from an inner wall of the pipe 3 by at least the simple wall thickness of the pipe 3.
