A vehicular muffler has a body with endcaps mounted on opposed ends thereof. The body has an outer wrap and an inner wrap. The outer wrap is sheet metal having opposed edges overlapping each other to form a closed figure. The opposed overlapping edges are an outer edge and an inner edge. The inner wrap is sheet metal having opposed margins overlapping each other. The opposed margins are an inner margin and an outer margin. The inner margin has a portion adjacent to the inner edge. The outer margin is positioned between the inner margin and the outer wrap to form a gap between the terminus of the outer margin and the terminus of the inner edge.

In a vehicular muffler having an elongated body, said body having an outer wrap and an inner wrap, said outer wrap being sheet metal, said outer wrap having opposed edges overlapping each other to form a closed figure, said opposed overlapping edges being an outer edge and an inner edge, said inner wrap being sheet metal and positioned within the outer wrap, said inner wrap having opposed margins overlapping each other forming a second closed figure similar to the first mentioned closed figure, said opposed margins being an inner margin and an outer margin, said inner margin having a portion adjacent to the inner edge, said outer margin positioned between the inner margin and the outer wrap defining a gap between the terminus of the outer margin and the terminus of the inner edge, said gap is variable in response to the temperature difference between the respective temperatures of the inner and outer wraps.
