ABSTRACT OF THE DISCLOSURE A stamp formed muffler is provided with a nonplanar array of tubes. The tubes are defined by at least one pair of nested formed members. The nested members include at least one external shell having a nonplanar portion and at least one internal plate having a nonplanar portion, with the respec- tive nonplanar portions being configured to be placed in gener- ally nested face-to-face relationship. The nonplanar configura- tion comprises an array of channels, such that an array of tubes is defined by the channels when the components are placed in nested relationship to one another. One or more chambers of the muffler are defined adjacent the nested formed members. The chambers may be defined by a single plate placed in register with the nested components or by a second pair of nested mem- bers. The nested pairs of formed members is effective in dampening shell noise attributable to vibration of the formed members.
