The ones with the bracket you do not need to cut, but the bracket is likely to bend. That's my green 06 getting the sliders on. I only had to cut the left side, right has an exposed motor mount. If anyone needs help, PM me, and I'll see if I can help you out. We used a dye-grinder (carefully) to get most of the fairing cut off, and then a sanding wheel attachment on a drill (designed for a dremel) to smooth up the cut.
