For those using a cannister ---here's a picture of two predrilled holes just above the fiberglass tunnel. They are not drilled through the tunnel itself so that will be up to you if you need them. Some will use mufflers and not want the through openings. In any case, they will provide a support location for your cans that do not require additional support. Nice touch and shows that the manufacturer is thinking about his customers.

No worries about the manual Tom. You know I wouldn't have used it anyway. It's my way of giving you a hard tie once in awhile
