I would say "bolt'er up then man"

do you know what you will use for exhaust manifolds or headers? would a large diameter Y pipe work for you? possibly even something from a stock vehicle but with large diameter pipe? all run down the pass side of the truck? diesels flow a lot and they only run a single pipe, something to think about? you could split it at the rear of the truck for the dual outlet look.
just a thought
