Leo A. ★★★★★ Oct 23, 2026

Exact fit on my RS-4 Adventure muffler, and the set screws were a nice touch to keep everything snug. Bolted right on without any modification needed. Feels solid and meets the forest service regs I needed for trail riding this season.

Isabella ★★★★★ Oct 22, 2026

Fit this onto my RS-4 muffler without needing any modifications, and the included end-cap collar lined up perfectly. The set screw feels sturdy and should hold up to the vibration. Glad to have a legal spark arrester that actually fits like OEM.

Swapped out the old spark arrester on my RS-4 muffler and this kit slid right in with the included set screw. The insert feels solid and the whole install took maybe ten minutes.
