ABSTRACT:
A muffler is provided for sound dampening of wet exhaust gases. The muffler comprises a canister, or housing, having an inlet and an outlet. The housing is preferably constructed of a plurality of resealable interlocking sections which can be disengaged from one another to allow opening and closing of the housing to permit exposure of the sound dampening element(s) for inspection and replacement thereof or to allow for removal, servicing and replacement of the sound dampening element(s) which are positioned therein. The sound dampening element(s) can be formed from a foamed, heat resistant moldable material, such as a closed-cell concrete.
