Ryan Y. ★★★★★

Took about 20 minutes to swap out the old insert, and the decibel drop is exactly what I needed for neighborhood riding. The build quality of the included washer and screw kit made installation feel solid and secure.

Carter P. ★★★★★

Installed this on my bike last weekend and the low-volume insert really tamed the bark without killing the whole tone. The decibel drop is just right for the neighborhood but still sounds good at speed.

Stella C. ★★★★★

Took about 20 minutes to swap in, and the decibel drop is immediately noticeable on start-up. The included low-volume insert fits snugly without any rattling, which is exactly what I wanted for street use.
