You can remove the entire top off your stock box and this works well. We use a DSP carbon box with the stock boot on our WR 426 (2002) that we race in Baja. It works great, but I use a modified Raptor Outerwear (top of air box replacement part available through White Bros.) on the top to keep filter replacement down to a minimum
