Customer Reviews (4.8 / 5 · 5 reviews)

Amelia O. ★★★★★

I was a little worried about installation, but it fit perfectly and the low-volume setting is noticeably quieter at the range. The decibel reduction is just right for my setup.

Steven ★★★★★

Dropped right into the RS-9 muffler without any modification needed. The sound level is noticeably deeper and more controlled than the open exhaust—exactly the change I was hoping for while staying within the local noise rules.

Sofia I. ★★★★★

Took about 20 minutes to pop the old insert out and slide this one in, and the decibel drop is noticeable right away even though it's non-spark arrested. Fits the 1.250" opening perfectly, no rattling or leaks after a few rides.
