ABSTRACT:
A nonmetal heat shield that is removably attachable directly to a muffler shell for preventing inadvertent contact with the hot shell surfaces of the muffler. The heat shield includes a plurality of raised boss portions for attaching the heat shield to the muffler shell. A non-metal spacer is located between the bottom surface of the raised boss portion and the fastening portion of the muffler shell to thermally insulate the heat shield from the muffler sufficiently to inhibit thermal degradation of the heat shield.
