I just finished installing permanent Yakima racks on my new 2001 LX. The factory rack with yakima doublecross racks bolted on that is an expensive option with only marginal performance. Instead I used the railrider1 towers and 54 inch tracks that are bolted to the roof. Only downfall is drilling 14 holes in the roof of my brand new odyssey. but Yakima sent me a hole placement sheet for the '99 that seemed to work fine. You don't have to remove the header because they have these nifty expansion bolts the anchor from the top. After the tracks are installed you put the railrider towers in and those are removable, so you can remove the towers and your odyssey won't look like it has racks at all because the tracks are only about 1/2 inch tall.
