If you're looking to drop the sound decibels of your RPM muffler here is what you need! This is a high flowing perforated quiet core insert that will fit directly into your muffler. This does require the drilling of a small hole to bolt the quiet core in place. Hardware is included! These are for RPM Mufflers only.
Not so much of a “quiet” core. But it does give it a little back pressure rumble when you let off. Sounds much better with it than without. People riding behind me don’t seem to think so but they are too far back to worry about.
