Fastway by Pro Moto Billet’s Spark Arrestors are proudly machined in the USA from 6061 billet aluminum. Our spark arrestors were designed as an economical way to quickly and easily convert stock, 4-strokes and some 2-strokes, to United States Forest Service (U.S.F.S.) approved mufflers— so keep your bike legal and looking great! Do your part in keeping noise levels to a minimum and riding areas open with our optional silent insert, which reduces the exhaust note by 3-5 decibels, for a more acceptable noise level.
Safe, quiet horsepower. That’s why we engineer each Pro Moto Billet Spark Arrestor Endcap to be USFS legal, quiet, and powerful.
Motorcycle-USA.com test results show an increase in torque, and a loss of 2db of noise over stock, simply by installing a PMB endcap and screen:
