I am not sure which headers fit well as I have not done this swap so hopefully someone else will give you an idea on that,and what would be the best cost wise.And most exhaust shops can do a decent job on exhaust but virtually all use compression benders which tend to reduce flow so even if you just invested in some mandrel bent tailpipes and downpipes you surely would be ahead on getting good exhaust flow.I know it can be a difficult area to decide which is the best way to go, so again good luck and hope all goes well
