If it's not too late, try MBRP performance exhaust in Huntsville. They have a fabrication department called Off Camber Fabrications that specialize in Jeeps. I have been talking to them and will be getting their roof rack and cargo carrier in the near future as well as their bumpers. They can supply (and install) just about any add on you want.

I am looking at the Congo Cage KargoMaster, I like it cause it tilts back to allow the use of the soft top up/down. Also the "no-drill" attachment really is a good thing in my opinion.
