The rusty end is usually the back end on it, as the exhaust gasses are heated to huge temps inside the cat, then blown out the back... thus the HOT gasses flow only in the back end.. the stuff in the front is only "warm"

as for the Cat itself, if it doesn't have markings on it for direction, then it doesn't really matter. the one I installed from them (for another .orgy member) didn't have any direction markings or anything. just bolt it up and go.

: Long shot, but these things are often rusty as hell. The rustier end (if there is one) is *probably* the engine end (higher temperature). As to the problems/consequences of putting it in the 'wrong' way round - I just don't know. Given the different bolt patterns, one would think that it did matter, but you just don't know.
