'P' Headers???

[XLT_66]

I came across an extra set of FMS Headers a couple days ago. They look the same as the ones that i put on my explorer, but i am not sure if they are the headers make for the 'p' heads. Is there any markings or anything that i could look at to make sure they are the p-headers before we rip apart a buddy's explorer to put them on there?

the passenger side will have a bung on it for the egr tube. also, they will look weird and dinky like the stock headers.

what year explorers have the 'p' heads on them? What years do not need the egr bung?
