In a vehicular exhaust system muffler, two telescoped tubes and internal panel are joined by a wholly mechanical joint. Two axially spaced beads extend about the tubes. The beads are integral to the tubes, annular, and radially outwardly extending. An annular flange of the panel extends along the outer tube. A plurality of integral, interlocking protrusions are simultaneously deformed into the outer tube and flange. The beads, flange and protrusions totally mechanically join the tubes and internal panel.
