Miles Y. ★★★★★

Took a while to arrive, but the low-volume insert kit dropped the dB noticeably on my setup without any noticeable drone. The included parts fit the existing muffler perfectly, and it was a straightforward swap in about twenty minutes.

Daniel ★★★★★

After a few track days with the stock baffle I finally swapped in this low-volume insert. The installation was straightforward and the tone is noticeably deeper at idle, which is exactly what I wanted.

Charlotte ★★★★★

I swapped out the stock insert for this kit and the drone on the highway is finally gone. The low-volume insert really dials back the noise without killing all the character. It was easy to install, just a few bolts.
