Ryan ★★★★★

Actually fits my RS-4 perfectly and dropped the noise level to something reasonable for a residential range. A bit loud if you skip the dampening wool, but with it packed properly, it's just right.

Scarlett V. ★★★★★

I needed a quieter option for my setup, and this insert kit dropped the noise perfectly for my range. The 94db rating was spot on, and installation was straightforward with the included hardware.

Jacob B. ★★★★★

Took about 15 minutes to swap out the old insert for this RS-4 kit, and the decibel drop is exactly what I needed for my setup. It's a solid, no-fuss part that does exactly what it's supposed to.
