I need to replace exhaust manifold on my 2002 SD 5.4L. The Ford replacement costs $150. Dorman and ATP make replacements which cost considerably less. Anyone had any experience with either of these?

 

 

Pay the money for the fords, aftermarket ones are super cheap and fail extremely quickly

 

I've been running the Dorman manifolds for over year with no issues. They review well on Amazon, too.
Either way, make sure you get stainless studs.

 

You could always get a good used one from a junkyard.

 

THANKS for all the responses. I think I will go with the FORD option. Doesn't seem like a job I would want to do more than once!

 

Watched the video, had hoped enjoyed the luck you had with yours.
2007 F150 5.4 3-valve, both front studs were snapped and exhaust was leaking.
My studs had 5mm ends, #7 top was my 1st attempt, the nut spun off, happy times, or so I had thought.
Next 2 tops snapped off, not a lot of force and they both broke leaving enough to weld on nuts and hopefully spin off, so far so good.
Could not get either exhaust pipe nuts off, both were so corroded there wasn't much left. So the top one I cut from on top, the bottom one I tried to air chisel off the nut, no joy, had to remove the starter, and those bolts were also very corroded, day later, starter out.
Then I was able to get chisel up to get nut free from stud and access the bottom studs, with starter there on this truck there was no way to get up in there from below, trany lines, vent tube, etc all in the way to get hands up there.
Bottom 2 both spun out with studs, not bad..
Now here is where I messed up, I should have dropped exhaust on both sides, there was no way to get the manifold off the studs when pressed up tight to the exhaust pipe. I cut the bottom stud, the top was free, no amount of wiggling got the manifold free of that stud, that is when I cut the lower stud from on top. If I had cut the cat off first, this stud could have been saved, both #7s could have been saved. But there was too much tension against the exhaust pipe, and even with prying and putting a small piece of wood up there to keep it down, not enough room.
So cat cut off in area where slip clamp or welding will repair. and manifold is pulled out, but on an F150 we do not get all the room you had and I think will either have to lift up engine to reach broken studs, or completely pull the motor out, that tower is in a different position on the F series and in the way even with short bits and right angle drill, would be very difficult... at this point I am almost wishing just swapped plugs and sold it as not enjoying the work yet to be done, just to do 1 side... None of my studs would free, no amount of heating cooling spraying oil, tapping on ends would free them up, broke sockets trying to spin them out... Will do more heat n cool to see if can get rear out, but drilling the 4 broken of welding a nut on the 2 will be no joy... I can see why some mechanics say they can't wait for this 11th gen to be in the scrap yards...
