Either way you go its gonna take fab work, especially if you try doing true duals. It would probably be way easier for you just to fab a y-pipe up for it.

Do a search for some ideas, I remember at least a few threads on guys making their own y-pipes. If your decent at welding you should be able to get appropriate pipes and weld it up.
