If this is true, then why couldn't I use a Fox H Pipe on my 94? I went to order one and they were out of stock on 94/95 H pipes, so I asked if a Fox one would work and they said it would not. Something about the collector flange being in a different spot.
No hijack intended...sorry
i got fox bbk long tubes and they fit.
I purchased Fox GT40 P headers from Ford Motorsports. They fit great, but I will have to have custom exhaust work done up to the header flange.

when you say fit, do you mean they went in without a hitch or they went in with some work?
I was looking at a set of BBK equal length headers of a fox 5.0 for my 95
