A motor vehicle muffler comprising a housing comprising two half shells, and an exhaust conduit having two ends. The conduit is disposed within the housing and is securely joined to the housing at its two ends. Filler material within the housing surrounds the exhaust conduit, the exhaust conduit being in contact only with the filler material between the two ends of the exhaust conduit. The housing has a length and a width and a depth, its length and width being greater than its depth, and at least one plate extends in the direction of the depth of the housing, between the half shells, and is securely joined to the half shells without touching the exhaust conduit. For this purpose, the plate has notches in which leg portions of the exhaust conduit are disposed in spaced relation to the plate. The half shells of the housing are joined to each other by a folded seam and are joined to the ends of the exhaust conduit by welded joints, and are also joined to the plate by welded joints.
