On the R2 the flex hose that runs from intake to the air box is long enough to take off the air box and turn up and run between bed and cab, I mounted mine to the cross bar with a 2 hole strap, no drilling or cutting anything, used a short pice of pvc pipe to clamp between flex hose and filter. looks cool and sounds great when you dance on it. the oem air box leaks too much dirt past the filter and why have a filter intake right in front of the rear wheel? I havn't had to clean the new filter for a long time now.
