Customer Reviews (4.8 / 5 · 5 reviews)

Ella ★★★★★

The decibel reduction on my RS-4 is exactly what I needed for a quieter ride, and the 1.500" insert fit perfectly without any modifications. Install took about 20 minutes, and the sound is noticeably lower without losing the deep tone.

Grace V. ★★★★★

I was skeptical about the fit, but this insert dropped perfectly into my RS-4 muffler and the sound is noticeably tamer now. The non-spark arrested design was exactly what I needed for my regular trail rides.

Adam B. ★★★★★

Took a few minutes to swap in, and the sound dropped to exactly the level I needed for a quieter riding area. The 1.500" fit was spot-on, no rattling or leaks after a couple hundred miles.
