My cj has always had fenderwell long tube headers. They look cool and sound nice. Real common for cj's.
Your other options are shorty headers (only edelbrock makes and are $$) or in-frame long tube headers.
I have never ran manifolds on my cj but I would say they are like any other car. Headers let the engine breathe a little better making a few more horses. Long tube headers pickup some low end torque as well.
I just happen to have a new set for sale. I am buying in-frame headers because I am building my jeep for more rocks than mud. If you are interested I will cut you a deal on them.
Does that help?
