Why not rebuild the motor yourself? It is not too hard to do.

I think I remember there being an aussie company that made a header for the 3.0. I thought about getting some local fab guys to make a custom long tube header set up. i am not sure how much benefit it will be.

I would build my own bumper over an ARB bumper. i am curious to see how you do your dual battery build. something I might be looking into. Good luck with the build.
