I have looked on this forum for some time now, and I know the question has been asked, however the question was never answered from what I can find. I have a 2015 Ram 2500 4X4 6.4 HEMI. I would like to install headers on and I’ve been told that long tubes won’t work because of clearance issues, so I would have to use “shortes”. Also that the 5.7 headers fit the 6.4 HEMI. Now once and for all will someone who has knowledge of this, answer this question and if there are headers that fit a 6.4 HEMI, if the 5.7 theory isn’t correct, where they can be found to fit the 2015 Ram 2500 4X4 6.4 HEMI??!!
