I've got a 1988 MJ Eliminator and am in the middle of an engine rebuild. I always do things myself and I like to do things right the first time. My problem is that I want to go with an all stainless exhaust from the head to the tip and I can't find a header for my truck. I have found plenty of headers for 1991 and newer Jeeps, but none for 1990 and older! Is there such a thing? Can I use a 1991 and newer header? What would the difference be?
