Victoria ★★★★★

I wasn't sure if this insert would fit my R-11Sq, but the tube slid right in and the included lock washer held it tight. It dials in the sound restriction perfectly for my setup and feels well-made. Really glad I grabbed this as an optional kit.

Leo N. ★★★★★

The lock washer and set screw made installation straightforward, and the insert tube fit perfectly snug on my R-11Sq. Exactly the sound restriction level I needed for a quieter setup.

Richard ★★★★★

Replacing the original insert was a 15-minute job once I realized the set screw is what locks everything in place. The lock washer really does hold it steady even after a few hundred miles of vibration. My exhaust note dropped to the quiet level I was hoping for.
