Abstract

A manifold for exhaust gases from a motor vehicle engine, includes upper and lower half-shells (18A, 18B) delimiting between them an exhaust gas pipe, and aligned bores designed to be arranged in the extension of the engine exhaust outlets, the half-shells having each a peripheral edge and being attached to each other via at least first segments (20A, 20B) of their peripheral edges welded to each other. The invention is characterized in that there is at least one median plane (P) passing through the bores and traversed at least twice by the first segments (20A, 20B).
