Well I have the notorious warped passenger manifold. I'm looking to replace them both with either shorties or long tubes and couldn't decide on which to use...then I found these www.amazon.com/gp/aw/d/B001CI2OMG/ref=mp_s_a_1_31?qid=1443929652&sr=8-31&pi=SX200_QL40&keywords=headers+f150&dpPl=1&dpID =41RIJyF7CgL&ref=plSrch they seem to be a good compromise as I was leaning towards the long tubes since I have a programmer and could get a tune to delete the cats. But if I could get close to the long tube gains and stay semi-stock for now that would be best. I know I'm going to have a shop do the headers and I'll orobably weld on a flow master 40 and turn down over rear axle when I get it back. Any suggestions on these mid tubes though? I can't seem to find anyone running them.

There is another link since the first isn't working.

 

I have pacesetters and i will never buy them again. if you do buy them get the head machined flat otherwise you will blow gaskets like crazy.

 

I have dynatechs. They are pics on my build page. They are the best dang headers I have purchased. They are gorgeous. Problem is cost $1,400 with cats. Would I do it again? Yes
