WHAT IS A MUFF PACK REPACKING KIT?   Muff Pack is a muffler repacking kit consisting of stainless steel wool  and a high temperature resistant insulation blanket.  Our stainless  steel wool is mechanically woven and formed into a strong blanket of  steel that provides an added layer of thermal protection and lengthens  the life of the insulation material.

WHY USE MUFF PACK?   Stainless steel wool is widely installed by muffler manufacturers and  professional racers. Motocross enthusiasts and racers around the world  have reported mufflers packed with stainless steel wool will last up to 4 to 5 times longer than by using fiberglass alone.

APPLICATIONS?  MUFF PACK muffler repacking kit can be used on most 2 stroke and 4  stroke engines in:  Cars, Sport and Touring Motorcycles, Motocross,  ATV’s, UTV’s, Snowmobiles, Jet skis, Farm and Industrial applications.

WHEN TO REPACK?   If your muffler’s exhaust tone is starting to sound louder or “raspy”  & if you are losing a little “bottom end power” your muffler  packing  has: either broken down and been blown out or is saturated with  oil or water.   Re-packing should always be carried out as per your  muffler manufacturers’ recommended intervals.

Our TEXSTEEL (needled punched mat) is widely used by OEM’s of  motorcycle, ATV, snowmobile and high performance automotive mufflers.    

It is also the product of choice by professional racing  enthusiasts for high heat absorption inside mufflers for 4 stroke and 2  stroke gas engines.      It is recommended, Stainless steel wool be used  in conjunction with ceramic or fiberglass mat, especially for carbon  fiber mufflers to prevent excessive heat cracking and discoloration.    When used in conjuction with ceramic or fiberglass matting, you can  expect the fiberglass or ceramic packing to last a longer time, so this  means additional life for your muffler between packings.  

For those concerned about stainless steel wool being flammable, it is  not.  It is different than carbon steel wool or conventional steel wool  (aka SOS pads) as found in grocery and hardware stores.  Carbon steel  wool is machined with oil.  So when a flame or spark comes in contact  with the steel wool, it is actually the oil burning, not the steel  wool.   On the other hand, stainless steel wool is not machined with  oil, so it will not ignite.

Produced with precision machinery by International Steel Wool to the highest quality standards.  Stainless steel wool is made from AISI 434 stainless steel. For more information, go to www.steelwooldirect.com
