I've got a set of lt heddman headers that I ordered for my 03 hemi ram that never got put on. I now have an 07 hemi and dangit they need to be put to proper use lol. question is, will these lt's I ordered for my 03 fit my 07?

 

I don't really know, but from what I have seen the 03 is mostly called out seperate on headers because the 03 has a single cat making the pipes configuration a little different. My guess is it shouldn't be a problem using them. But that's a guess.

 

I would put the truck on ramps and take one under there with you and test fit it. Or call the manufacture and see what they say.
