Violet E. ★★★★★ Oct 23, 2026

Having a track day next weekend, I swapped out my standard baffle for this low-volume insert and it dropped the noise just enough to pass the decibel check without killing all the power. The included gasket made installation clean and hassle-free.

Really easy to drop in and the hardware was all included. Cut the bark from my aftermarket muffler to just the right level for neighborhood cruising.

Installed the insert kit on my TRS muffler this weekend and the fit was spot-on, no shims needed. Definitely noticed the lower volume when I fired it up, exactly the sound restriction I was after for my neighborhood.
