You can use B-body and E-body log style manifolds. They work, I've installed them on both of my Dusters. Of course, A-body 340 exhaust manifolds work as well, but can be more expensive depending on year. Headers, all brands will work, some fit better than others. I just installed a set of Dougs and they fit like a glove, but I've also installed the cheapies like hedmans, cyclones and the such, and they fit well too - after a ding or two (and they hang a little lower). Headers can be a challenge if you are not used to putting them on. But here is the basic idea - a video I made.
