Madison F. ★★★★★

Installed these inserts in my RS-8 and the low-volume reduction is exactly what I needed for quieter cruising. The round-exit design fit perfectly into the existing cutout without any modifications. Took about 20 minutes to swap them out.

William I. ★★★★★

Had to swap out my restrictive baffle and this 1.625" kit gave me back a nice low growl without being obnoxiously loud. The round exit fit perfectly into my RS-5, no modifications needed. Exactly the middle-ground sound I was after.

Evelyn U. ★★★★★

Installed this kit on my RS-8 and immediately noticed the lower tone—still has a good bark but way more bearable for daily riding. The 1.625" round exit was a direct swap with no issues.
