The exhaust component as claimed in claim 1, wherein the wall elements, at least in most of the wall, define an outer limit of the exhaust component. 7. The exhaust component as claimed in claim 1, wherein one of said two wall elements and two additional wall elements, which are connected to the wall elements surrounding the inner lines and have each a pair of metal shells and a layer of heat-insulating material provided between these shells, surround catalyst means in cross section. 8. The exhaust component as claimed in claim 7, wherein the two additional wall elements are directly and rigidly connected to the wall elements which surround the interior spaces of the inlet lines. 9. The exhaust component as claimed in claim 1, wherein the wall elements have finger-shaped sections which are separated from one another by intermediate spaces and together in pairs surround the inner lines of different ones of the inlet lines. 10. The exhaust component as claimed in claim 1, wherein the inner collection wall is rigidly connected to at least one of the wall elements by a bush adapter for supporting a lambda probe that projects through the bush adapter into the inner collection space. 11. The exhaust component as claimed in claim 1, further comprising an inlet port for each inlet line, and an outlet, wherein the wall elements together tightly limit an interior space in which the inner lines and at least a substantial part of the inner collection wall are located, and wherein the interior space forms the intermediate space containing at least one of a substantially stationary exhaust gas and air. 12. An exhaust component, comprising at least two inlet lines for connection to an internal combustion engine and each having an inner line; and a wall having two wall elements, wherein each wall element has two metal shells and a layer of heat-insulating material which is located between the shells, wherein the two wall elements have edge sections which are connected to one another and together, in cross section, surround the inner lines of all the inlet lines, wherein each inner line is, in cross section, at least partially separated by a hollow intermediate space from the wall elements which surround the inner line in cross section and delimit an exhaust passage, wherein the exhaust component further comprises an inner collection wall which is mostly separated by the hollow intermediate space from the wall elements which surround the inner collection wall in cross-section, and which delimits an inner collection space, wherein the inner collection wall is rigidly connected to at least one of the wall elements by a bush adapter to support a lambda probe that projects into an inner collection space defined by the inner collection wall, and wherein the inner line of each inlet line has an inlet end section rigidly connected to the two wall elements, and an outlet end section connected to the inner collection wall and displaceable with respect to inner collection wall, and wherein the exhaust component further comprises an exhaust manifold including said inlet lines. 13. The exhaust component as claimed in claim 12, wherein each shell is a single piece, wherein the shells which belong to the same wall element are connected to one another essentially along an entire circumference of each shell and are designed to be sufficiently strong for the connected wall elements to be self-supporting, and wherein at least a substantial part of the wall comprises exclusively the wall elements. 14. The exhaust component as claimed in claim 12, wherein all the shells of the two wall elements which are connected to one another at the edge sections are in contact with one another, at the edge sections, at least in pairs and are joined to one another
