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 gas engines.      It is recommended Stainless steel wool be used in conjunction with ceramic or fiberglass packing for additional noise dampening, 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.   TESTS HAVE INDICATED MUFFLERS WITH STAINLESS STEEL WOOL CORE WRAP WILL LAST EVEN 5 - 10 TIMES LONGER THAN BY USING FIBERGLASS PACKING ALONE.

For those concerned about stainless steel wool being flammable, it is not.  It is different than carbon steel wool or conventional steel wool 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
