Abstract
A method for filling a muffler shell with a fibrous material includes providing an outer muffler shell, applying a temporary form to the outer shell to define a muffler chamber within the outer muffler shell, and wetting the fibrous material by forcing moisturized compressed air into contact with the fibrous material. The wetted fibrous material is inserted into the muffler chamber, and the temporary form is removed from the outer muffler shell.
