The Thermal Zero Power Pack muffler packing kit contains a (1/2″ thick x 12″ wide x 24″ long) section of 4 pound density ceramic material.

Our ceramic muffler packing kits are far more dense than normal fiberglass packing material allowing the muffler that is repacked with our material to have a much better tone. Ceramic material is also superior to fiberglass in that it is much more durable and able to handle nearly three times the amount of heat than fiberglass. Our packing kits have sufficient heat resistance (2500°F) where they can also be used on pottery kilns, wood burning stoves, glass blowing furnaces, etc...
