Abstract

The invention relates to an exhaust manifold for motor vehicle engines, in which the inner pipe, of flexible design at least in certain sections, is supported on an outer pipe, thermally insulated by the said inner pipe and designed to be rigid at least in the axial direction. As a result, thermally induced distortion effects and changes in length are eliminated or reduced.
