Many off road areas require some form of spark arrestor to limit the chances of fires. Empi has a variety of spark arrestor assemblies to choose from The 3" and 4" disc kits are for clamp on or weld on installations. The 10" and 17" mufflers are stainless steel outer shells with 4" discs for fine tuning of your exhaust restriction. All of the assemblies come with long enough screws to add additional discs if your HP needs dictate it. The 10" muffler is also available with or without a mounting bracket so you can custom fit it to an existing exhaust system of your choice.
