Hannah ★★★★★

Swapped out the stock insert on my RS-2 and the 99db rating is spot on for my setup, it took about ten minutes with basic tools. The kit comes with everything you need, and the non-spark arrested design fits my needs perfectly for track days where sound limits are strict.

Madison ★★★★★

The decibel drop on my RS-2 is exactly what I needed for the neighborhood. The non-spark arrested design keeps things simple, and the install took under an hour with basic tools. Quiet enough now that my neighbors actually waved hello instead of glaring.

Henry ★★★★★

Swapped in this low-volume insert kit to tone down my RS-2, and the difference was immediate—noticeably quieter without choking off performance. Fit perfectly with no modifications needed, a solid upgrade for anyone wanting a bit more neighborhood-friendly decibel level.
