Abstract

An exhaust manifold for an internal combustion engine includes an inner duct with flanges for connection to an engine. The inner duct is enclosed by an envelope consisting of two shells which are interconnected at their edges by seams. Between the inlet flanges, the seams are disposed at a substantially greater distance from the inner duct than in other areas such that, in a cross-sectional plane disposed between, and extending normal to, the flanges, the envelope has drop-like shape.
