move it to the box? so you want to run true dual? why not just run a 3" pipe back to a 1 inlet/2 outlet muffler? or run the drivers side pipe on the passenger side. thats how hookers header back true dual exhaust system is for my 78 D200.

you can take it to an sxhaust shop and have them bend the pip so that it runs down on teh outside of the frame but it up above the body line. my D200 had that on it when I bought it. the only thing you could see was the bends right after the manifolds and even that wasn't that bad.
