i have an 03 400ex and prices for an aftermarket hood scoop start at about $50. some of these (450r hood) even require further heating and manipulation before theyll sit nice and flush, or so ive heard. I made my own out of plastic from a large rubbermaid container. i mocked one up out of cardboard, used it as a template to cut the plastic, used a dremel and a soldering iron to shape it and stuff. i thought the results looked good so i thought id post pics on here.
