Sofia L. ★★★★★

Installed this on my RS-3C and the decibel drop was exactly what I needed for my neighborhood. The fit was perfect and the kit included everything required for a quick swap.

Henry ★★★★★

Swapped out the stock insert for this low-volume kit on our RS-3C and the decibel drop was immediately noticeable at idle. Fits right into the existing muffler with no extra parts needed, and it's holding up fine so far. Exactly what we needed for the stricter sound rules on our track days.

Natalie ★★★★★

Had to change sound levels for a new track and this insert kit did exactly what I needed. The non-spark arrested design is perfect for my setup since I don't need a spark arrestor. Dropped the noise just enough without killing all the tone.
