Samuel ★★★★★

I needed a quieter setup for my R-11Sq-R, and this insert kit did the trick—the collar fit snugly without any wobble. Installation took maybe ten minutes with the included hardware.

Avery P. ★★★★★

I needed a little more restriction for my specific setup, and this insert kit’s collar fit snugly into the muffler body without any fuss. The set screw locked everything in place in under a minute, making it a quick job.

David R. ★★★★★

The set screw and lock washer made installation feel rock-solid, and the insert tube slid in without any fuss. Took maybe ten minutes total, and the sound restriction is exactly what I needed for my setup.
