I heated up and welded the cracks in my 4.0 header when I put the stroker in 14 years ago. It cracked again awhile back and it is starting to leak enough that it annoys me, I also want to put a quieter muffler on it that will make it that much worse.

I haven't looked at the 4.0 market in at least 5-8 years, does anyone have any expierience with a good cost effective header? Looking for build quality more than performance, I can't see any of them making much difference over the stock one power wise. This is four a 97 4.0 XJ

I think I will upgrade to the later model intake while I have all that crap off. My poor little XJ needs some restoration so I will probably show it some love this winter.
