351 Exhaust
As many of you know I am rebuilding a 5.8L from a 95 F250 to put into my 94 F150. So I am going new exhaust all the way back and using Long Tube Headers. I am having trouble finding a kit for this application and was wondering if any of you had some insight to add. The headers I am using are 87-96 Ford F150/250 Pacesetter Long Tube Headers w/ARMOR*Coat those. What I would like is either 2.5" true duals all the way back or 2.5" pipes to a 3" Y into a 3" cat with a 3" muffler. Then exit with 2 2.5" pipes and come out under the rear bumper.
Looking for the nice deep throaty sound but not necessarily loud.

You won't find a kit these trucks are too old now nobody pays them any attention. And because of the location and size of the gas tanks both pipes in a dual setup have to run down the passenger side if you want them to be tucked up under the truck, so there's not much point in true duals unless you just want bragging rights to it or something. A single midpipe with dual exits can still be done of course but you're going to be fabricating the section between the headers and the 2into1 collector.

My exhaust on my 96' XLT has hedman long tube headers from JBG. I have duals coming off the headers to a dual in/out thrush muffler then it exits on each side of the rear. On the passenger side its pretty much a straight shot down the side of the trans to the where the muffler is over the skid plate but the driver side comes down by the side of the trans then wraps closely under where the trans meets the transfer case and into the muffler.
It sounds really nice but personally it is a pain if I have to ever pull the trans again because it has to be hacked up. Although it's the 3rd exhaust on my truck -_- I might just go with duals again which went from the headers, wrapped around the frame and ran along the outside of the frame and exit before the rear tires on each side. It was tucked away and sounded nice but was difficult to get the O2's to go to it.

I was hoping more for a bolt on system and possibly even stainless. I just like the thought of a factory mandrel bent set of pipes that I get to install. Oh well looking like a muffler shop it is.

I have done both of these.. had a muffler shop bend up some pipe and I have also built a couple of my own using mendrel J bends and straight sections. It wasn't that hard but it did take a whole day to put it together.. lots of test fitting involved. The mendrel pipe system easily outperformed the muffler shop setup too, both systems used 2-1/2" pipe but compression bends reduced that to about 2" in some areas so there was a fairly obvious difference in power and sound when I first got my own creation installed.

Well Cnanski let me ask you this, Is the gain from Long tube to Short tube headers that big a difference? For the Shortys I can get exhaustlike I want all the way back. I know I was aiming for lo-mid range torque but I also have over builyt the motor a bit frm where we started talking. My guess is I will be ushing closer to 350hp and I'd be willing to sacrifice a little HP and Torque for a nice bol on appiation exhaust. The shorties are also 50 state legal for emissios and I can always swap them in a few years when I reach 25 and can eliminate all the smog crap.

I just found an article others contemplating this same thing might be interested in reading. My gains will be slightly better than those in the article because I am replacing all the way back with new high flow parts.

Well you could also do like Edgethis has on his 94 bronco. I believe he has Longtube headers, then has a custom bent 3" y pipe to a 3" in/out hi-flow cat to a Flowmaster 40? Not entirely sure on that one but from the video he posted it was pretty throaty.

There isn't a hugh difference between longtubes and shorties when there is an equally well designed exhaust behind it, they're both healthy upgrades from stock so you're not giving up a lot to gain a simple bolt-on install.

From the data in that article I am really starting to lean towards shorty headers. The los is under 15hp, though there is slight loss all the way through the rpm range in torque. But I still don't think it will effect me as much.
Here is the Y pipe I will use with shorty headers unless I can find another with the same specs. I am also curious what the flange behind the cat is for.

I agree I wish I could find a way to bolt the Gibson Stainles exhaust to that flange.
Let me as everyone this, am I going to flow too much with this exhaust and should I shrink the pipes to add a little resistance? I am about to drop 1300 dollars on the comp,lete exhaust and wouldnt mind any advice.

That is a ball and socket flange on the Bassini Y pipe, it's used because it allows a good seal even if the pipes are misalligned a bit, and you can buy a weld-on ball and socket set to add to any exhaust system..
