Headers are not all that expensive to begin with, is it really worth the attempt? If it were me I'd get new headers in the configuration I wanted. My headers (they came with the CJ) run inside the frame, an over all safer place for them to be. Also, headers are a pain to live with. They are hot, they are bulky, they are difficult to keep tight, they do not help with low RPM torque. If I could easily do it I'd go back with the stock manifolds.
Thanks for the advise, not my first jeep with side headers. I am aware of the cost involved and everything else you talked about. Not eveyone shares the same tastes. Open forums ae like a box of chocolates, never know what your going to get. I learn alot from forums and appreciate the knowledge. Just have to muddle through the extra advise at times.
