Abstract
An exhaust line element for a supercharged heat engine includes an exhaust manifold and a turbocompressor. The manifold includes at least two separate inlets equipped with connection elements at the outlet of the cylinders of the engine and a discharge outlet for the exhaust gases which is common to the different inlets and which is connected to the inlet tube of the turbocompressor, a bundle of internal tubes converging towards the outlet, each from an inlet of the manifold, and an outer casing inside which the bundle of tubes extends. The inlet tube and the discharge outlet are connected by a peripheral weld seam provided between the outer casing and the inlet tube, and the bundle of tubes is left free from any welding to the inlet tube at the discharge outlet.
