Quiet Core Insert

The quiet core insert can be used with most (see below) DR.D exhausts. The insert can be installed and removed very quickly. And as the name suggests it significantly reduces the sound level. Although you will experience a mellowing of the power by installing the insert there is not a significant power loss.

For actual sound level reductions by model please contact tech support.

*This product does NOT work with a 2010 CRF250 DR.D Exhaust System or a WR250X 08-09 exhaust, Does not work with DR.D's MINI Bike Exhausts.
