Systems for and methods of filling mufflers with fibrous material

A system for filling a cavity of a muffler with a fibrous material, the system comprising:

• a muffler body having a first open end and a second open end;
• a perforated insert;
• a texturizing nozzle;
• and
• a vacuum source;
• wherein the muffler body includes a baffle that divides at least a portion of the cavity of the muffler into a first chamber and a second chamber;
• wherein a pipe extends between the first chamber and the second chamber, a portion of the pipe in the first chamber lacking perforations;
• wherein the texturizing nozzle is operable to introduce compressed air and the fibrous material into the first chamber;
• wherein the perforated insert is operable to interface with the first open end of the muffler body to fit over the portion of the pipe in the first chamber, and the perforated insert is operable to be positioned at a first location in the cavity when filling the first chamber and at a second position in the cavity when filling the second chamber;
• wherein the vacuum source is operable to interface with the second open end of the muffler body;
• and the system is operable to draw compressed air from the first chamber, through the perforated insert, and into the pipe.
