I used the breather tubes out of a raider. They are angles and contoured to the hood liner nicely, but weren't tall enough for inside the hood to prevent water intrusion. So I used some of the 2 inch pvc i had leftover from my drain valve and pressed(read: big hammered) it into the raider breather mounts. It worked quite well. The tubes were cut to length once i tried the hood on too, they are very long in the pics above. Had some underpad leftover so I did the chinpad as well.
