The headers I'm using are Speed Engineering model 25-1021. They are kind of a short-to-mid length header. I was considering their long tube headers, but their website specifically states they do not fit 4WD. I didn't want to chance it.
I fit up the headers and so far they look good. I'm happy with the choice because I'll have to custom fit the exhaust around the transfer case cross member anyway. If I went with long tubes, I believe they would have come down lower and pointed directly at the cross member and it may have been more difficult to pipe around.
