Matthew D. ★★★★★

Dropped right in with no fuss and the low-volume design took the edge off that harsh exhaust note without killing all the sound. Exactly the kit I needed for tightening up the noise on my application.

Aurora J. ★★★★★

Finally got around to swapping my insert for this low-volume kit and the difference in tone is fantastic. The 1.000 inch opening tightened up the sound without killing airflow. Exactly what I needed for my specific noise restriction.

Samuel ★★★★★

Went from the restrictive stock setup to this low-volume insert kit and the tone changed exactly where I needed it. The 1.000” size slid right in without any fuss, and the decibel drop is noticeable without killing the bark entirely.
