I, uh, think you crashed the wrong party. There are other forums here at FTE for your year of F150. And there's also one for 5.0's.

 

Searched the threads on Y pipe, this discussion looked like the best one

 

Hey, no problem, but we people in the V10 forum would have no idea what fits your truck, unless one of us has some experience in it - the right forum will take care of you

 

I can tell you I pulled a ypipe from a early 90s v8 f150 when I put a 302 in a nissan 720 pickup just for the flanges. It looked like it would flow pretty well in stock for.

For that 302 you can find TONS of info and parts. I'd check out some mustang forums.

 

Back on topic...Art, how are your Hedman's holding up? You've had them on for, what, 3 years now? Aside from the ball socket fiasco, how are the headers themselves holding up?

 

I gotta go look - the poor thing has been sitting so long I can't even remember the last time I started it - last I looked, the finish was still looking pretty good - a little "cloudy" and not so shiny, but that has more to do with the time it sits and the salt it saw during the winter (which was somewhat brutal by Long Island standards).
