To reduce the risk of fires, many off-road locations now need some type of spark arrestor. EMPI currently offers a wide range of spark arrestor assemblies. The 3\u2033 and 4\u2033 disc kits may be clamped on or welded on. The stainless steel outer shells on the 10\u2033 and 17\u2033 mufflers include 4\u2033 discs for fine-adjusting your exhaust restriction. All of the components have long enough screws to allow you to add more discs if your horsepower demands it. The 10\u2033 muffler comes with and without a mounting bracket, allowing you to custom attach it to an existing exhaust system.<\/p>\n<\/body>","protected":false},"excerpt":{"rendered":"
