Customer Reviews (4.6 / 5 · 5 reviews)

Thomas ★★★★★

Bolt pattern lined up perfectly with my existing header, and the screen mesh is tight enough that I know it'll pass a forest service check. Took maybe twenty minutes to swap out, no drilling or mods needed. Glad I grabbed this before the season started.

Jason ★★★★★

Took it out on the trail this weekend and the 1.5" fit snug on my RS-4 without any extra fiddling. Glad to have the USFS approval stamped on it so I don't have to worry about ranger checks.

Thomas J. ★★★★★

I had to swap out the old spark arrester because of forest service regulations, and this one slid right on with no hassle. The 1.500" size matches the RS-4 muffler perfectly, and the build feels solid enough for trail riding.
