<p>The component has a self-supporting jacket comprising a porous cellular constructed foam (1), where the foam is made of a self-supporting design and a closed-pore configuration. The foam forms a layer of a multi-layered foam structure that includes a layer of open-pore foam and a layer of closed-pore foam. The jacket partially comprises one of non-porous outer and inner surface regions, where the surface regions are formed from a pipe. The foam includes metal and mineral material, and the jacket includes one of different densities and material and wall thickness. An independent claim is also included for a method for producing a component of an exhaust system.</p> |
