'11 3.8L in a '07 wrangler
I like your idea! For the headers you will find some useful information in this thread: https://www.jk-forum.com/forums/modified-jk-tech-2/gibson-headers-9109/ Feel free to ask any questions upfront. I would also be interested in your opinion about the headers once you have returned from Moab. Good luck with everything!
Think about heat wraps. On the passenger side you have the supercharger sitting right above the header. If the header can melt battery boxes, it can also damage a supercharger I suppose. From what I have read you could also reuse the factory heat shield on the passenger side. It should require just some minor trimming.
