  • Vehicular muffler with heat shield
    Patent number: 5281778
    Abstract: The vehicular muffler assembly of this invention includes a muffler which has a elongated shell. An inlet communicates with the interior of the shell to provide a port for entry of exhaust gases from an internal combustion engine to the interior of the shell. An outlet communicates with the interior of the shell to allow exhaust gases to leave the shell. A heat shield is mounted on the exterior of the shell. The heat shield is symmetrical and has an outer wall. The outer wall has a weld skirt which is integral with the outer wall. A plurality of discreet welds spaced along the weld skirt fixes the outer wall to the shell. A slot opening is formed in the weld skirt between adjacent discreet welds.
