After a miserable experience trying to order Hedman headers I gave up and ordered a set of JBA and a SPD Y pipe. Both were in stock and at my house in 4 days! I started the disassembly Saturday morning and worked till around 4. I soaked every bolt the day before with PB blaster, I was able to impact the collector and Cat flange bolts with no problem. With the air cleaner assembly out of the way I worked on the driver's side. Every nut or stud came off easily. YAY The passenger side had to be more difficult. Remove the tire and fender well liner to get access, First nut I tried came off way to easy and sure enough the stud broke just below the head, Two other studs broke as well, one has about an inch showing. Fortunately they are accessible thru the fender so I can weld nuts on them. I had to do this before on my 02 so I'm feeling comfortable. Once I have the JBA's on I am going to retrofit the crappy Ford Y with the SPD Y.
the JBA gaskets look pretty good. Today I was able to get the longer stud out but the other 2 I can't get the weld/nut to grab. I'll try some more on Wednesday
Only suggestion I have is to use Liquid Wrench for trying to loosen rusted bolts/nuts/parts. I've heard decent things about PB Blaster but when Project Farm (YouTube) did a comparison between about 6 or 7 penetrating sprays or other "homebrew" ideas, Liquid Wrench came out ahead of the rest of the competition. And although I believe WD-40 IS NOT ACTUALLY meant for rusted bolts (I think it's actually meant to be more of a moisture dispersant than anything else), it came out behind as well. WD-40 just has a good history of marketing (obviously). The sad thing is, I can't find Liquid Wrench at Walmart so they must not carry it and have to get it at our local Runnings so it's about $1 or $2 more than it would be if Walmart stocked it.
Haven't heard about a V-10 header install in a while so hope it goes well from this point. Dealing with rusted or broken studs/bolts/nuts sucks *** but it's like the V-10s came from the factory that way. I don't look forward to having to maybe do mine one day. Thankfully, even though I think I have 2 on one side and 2 or 3 on the other, I don't really have a "leak" and just hear a slight sound from time to time when it's cold and nothing annoying.
I'm curious to know how the power difference will be as well as fuel mileage (better or worse).
No I don't think they were.
I have a tuner from 5 Star to install when I'm done.
I know long-tube give the higher numbers, but would be curious these JBA short-tube numbers. There might actually be a decent gain in the RPM range that matters most.
If I was to do it (which I'm close), I'd get those JBA's and a 5-Star tuner as well and run a before and after on the dyno too. Might be "disappointed" by the numbers, but it's got to breath better with those on there (including SPD Y-pipe)

Keep us updated!
I can't remember for sure but wasn't that stupid "bottleneck" in the Y pipe actually SUPPOSED to be a "good thing" for tuning purposes? I'm sure someone will come in here and correct me or I can go and search but I can't remember if I read somewhere that if you take that out and try to "open the exhaust up" by putting either actual dual exhaust on it or making that "bottleneck" larger that there is actually a reduction in power.
Or, is it for "tonal" (and NOT "tuning") purposes to make the exhaust "sound" a certain way? Maybe that's what it was.
I too would love to see before and after numbers. I have a 2002 and have a basic tune on it from a really old SCT tuner that came with a 2005 F-250 with a 6.0. I believe it's only about 18 hp and 22 or 24 torque but maybe it didn't actually do anything and it's all in my head. Unfotunately, I don't think we have any local dyno shops in my area so I'll have to check to see what it would run. I love testing with actual data to see what's what.
What I understand is with stock manifolds and replacing stock (restricted) Y-Pipe, there's almost always a drone. (the original 99 maybe 2000 too V10, didn't have as restricted Y-Pipe), but ~2000-2004 Y-Pipe is definitiley restricted to eliminate drone with the stock manifolds.
Almost all real world experience (on this forum) with headers and newer (SPD style) Y-Pipe experience power gains with no or little drone.
As far as Y-Pipe and/or Headers(long-tube) on the Dyno?
The necked down Y pipe (it’s actually a T pipe) was to eliminate “exhaust flutter” (heard by some but not all….).
I have the long tube Banks headers (no longer available) with Y pipe and 5Star’s tunes (always run the 89 octane performance tune) and there is a very noticeable improvement over the stock setup (results from my calibrated butt dyno).

What I don't understand is why 5-Star doesn't have power figures for the 2005 and newer models on their site. They have 2 videos from YouTube (which I've seen multiple times as I'm sure other people interested in the V-10 have as well) but in the videos, they are promoting the newer 3-valve versions of the V-10 with a 2008 F-350 (SRW) and 2009 F-250 for comparison. I wish they would have the figures on their site for the newer engines. The older versions are just not that desirable for various reasons.
Regardless, the gains in the graphs are at least something worth while especially if you consider from stock to the full Y pipe AND headers with the new tune even if it is for the earlier versions.

It is on there and it's dramatic, it's just called 3V (for 3 Valve) The stock manifolds on the 3V are very header like and has no Y- (T) Pipe restriction the '00-'04 have.
