One thing to keep in mind, if you have the mid chassis (left side) fuel tank, duals down that side are not possible unless they are outside the frame. Look at a Walker or other exhaust catalog and the 1984.5 - 1987 460 system, it is nice big duals to the muffler and is quite free flowing (sounds nice too).
