Customer Reviews (4.6 / 5 · 5 reviews)

Nicholas ★★★★★

I was pleasantly surprised how easy the install was—just swapped out the old insert and bolted it right in. The 1.250" size fit perfectly on my RS-2, and the sound dropped exactly as needed for my local track days.

Emma I. ★★★★★

I ordered this insert kit to tone down the sound on my RS-2, and it dropped the volume just enough for my neighborhood without killing the rumble. The 94db rating is spot-on, and the 1.250" size was a perfect fit.

Ryan M. ★★★★★

The decibel drop is exactly what I needed for quieter neighborhood rides, and the 1.250" fit was spot-on without any extra shimming. Installation took maybe fifteen minutes once I had the old baffle out, and the non-spark arrested design keeps things legal on the trails.
