this is how i ran my snorkel, the paint is KRYLON spray paint, just before you paint wipe down the stuff to be painted with pvc cleaner the paint will stick better, straight from air box with 1 1/2' flex up to 2" pvc fittings route them how you like. i also cut some 2'' pvc in half and put it over the flex by the motor. 1 shorty for trail riding just screw on tall one when goin deep.
use tread tape on treads also called "T TAPE" i bungie the tall one between the front rack and plastic.
note the bearing grease to help seal the air box.
the only hole i cute was the one through the fender.
hope this helps...
