Abstract: An exhaust component comprises a main casing and at least one partial casing pressed against the main casing. In a developed state, the partial casing has an elongated shape along a longitudinal line and is defined along a transverse direction, substantially perpendicular to the longitudinal line, by two side edges opposite one another. The partial casing has a given developed longitudinal length. The partial casing has no fastening to the main casing on at least one longitudinal segment, and the longitudinal segment extends from one side edge to the other and extends in total over a cumulative developed longitudinal length of at least 20% of the given developed longitudinal length.

Abstract: A manufacturing assembly for manufacturing a metal part comprises a flattening module having a trolley and at least one pressing roller. The flattening module is movable along a hemming of the metal part. The flattening module comprises at least one pressing actuator that is arranged to move the at least one pressing roller in a determined pressing direction relative to the trolley and to place the pressure roller bearing against the free surface such that the at least one pressing roller exerts pressure on the free surface in said determined pressing direction. The pressure increases auto-adaptively with an altitude of the free surface in a direction opposite the determined pressing direction.
