So I would like to try and figure out how to do this. I have a 2012 jku, so the exhaust is an issue. My thoughts are to move the resonator forward and relocate the evaporator. What do I do for the muffler? I want it to perform as close as possible to the stock exhaust (needs to be similar in level of sound, or boss will not approve). Additionally I am a Florida resident, but I am in the Navy and may get stationed in San Diego, so I will have to pass a California smog check for base access.
Instead of the long ranger, there is a place up the road that makes custom aluminum gas tanks, so I think I might can get something that will fit in the space based on what I can do with the exhaust. On jkforum there is a partial write up on using a TJ tank as an aux tank in the back, but that brings up my next question on the best way to plumb it all up. My thought is to run everything to empty into the factory tank. Figure I can use factory filler for two tanks and then a separate filler for the third, but I am open to any ideas as this certainly is not my specialty.
