Abstract: A connecting flange for mutually connecting two tubular components including a flange body annularly surrounding a flange longitudinal axis with a first flange contact region and a second flange contact region, which is arranged in the direction of the flange longitudinal axis at a distance from the first flange contact region. At the first flange contact region, a first inner circumferential contact surface for contact of the flange body against an outer circumferential surface of one of the components to be connected to each other via the connecting flange is provided, and, at the second flange contact region, a second inner circumferential contact surface for contact of the flange body against the outer circumferential surface is provided. An insulating recess extending radially outward with respect to the first inner circumferential contact surface or/and the second inner circumferential contact surface and open radially inward is provided in the flange body.

Abstract: A silencer for an exhaust system, more preferably of a motor vehicle, is provided with a silencer insert arranged in a silencer housing. The silencer includes a jacket, with at least one pipe section penetrating a through-opening of the jacket. Through welding of the pipe section to the silencer insert a weld seam formed pressure-tight between pipe section and jacket is relieved of mechanical load.
