Ava M. ★★★★★

Swapped out the stock insert for this spark-arrested kit and the sound difference is exactly what I needed for trail riding. The install was straightforward, just a few bolts, and it feels solid on the bike. Very happy with the decibel drop for our local riding areas.

Stella E. ★★★★★

Took this kit to tone down my RS-4 for a sound-restricted event, and it bolted right on no extra parts needed. The spark arrestor screen is well-built and the overall decibel drop was exactly what I hoped for.

George P. ★★★★★

Needed a quieter setup for the trails, and this spark-arrested insert kit dropped the decibels noticeably while keeping the RS-4’s tone intact. Bolt-on install took maybe twenty minutes, and the low-volume insert feels solidly made. Exactly what I was after for sound-restricted areas.
