I am looking to replace my factory manifolds due to the fact that the right one has a crack in it and I am looking to upgrade to get a little better torque for hauling our 2-horse trailer. My truck is a 1989 F-350 Custom Crew-cab Dually 2WD Automatic.

I am looking at long-tube headers, but am trying to track down a y-pipe to connect them to the exhaust without much of any mods. Any ideas as to what I should look for and where to find it? I was thinking about Hedman Hedders with a Walker Y-/H-/X-pipe from Summit, though I am open to other options. Also, will headers for a 4WD also work on a 2WD?

Thanks for any help as the search I did came up with mostly 460 stuff.

 

I dont know of any long tubes that have a y pipe for bolt on installation. If you are looking for something along those lines then shorty headers would be the way to go

 

Being that you have a 2 wheel drive you can buy an X-pipe kit to go behind the long tube headers, then finish off with the mufflers of your choice and some tail pipes. If you want to keep it emissions legal there is enough room to put the cats between the headers and the X in the x pipe. Summit has a universal kit that can be welded or put together with clamps.

Call Stan's Headers. Last time I talked to them they said they had headers and a y-pipe for my 93. They design and fab their own stuff. Be prepared for sticker shock though.

What about just long tube Hedman's? I figured I wont be able to use the factory y-pipe with it. I'm not trying to go all out with a completely new exhaust as I don't have $800 to spend on this. The truck already has a dual split after the cat, so I'm mainly trying to find something that will work from the engine to the cat without too much modification and without having to replace the entire exhaust.

The main reason I'm looking into this is due to the fact that the right manifold is cracked, so I figured with a little more money, I could have a little better exhaust.

 

I would just install the longtubes yourself and have a shop bend up some pipe to connect it to your existing system

 

That's gonna be the cheapest solution next to just replacing the manifolds with shorties. As far as I know there are no over-the-counter Y/X/H pipes for longtube applications on these trucks, they're just too old now so aftermarket suppliers have no interest in developing new parts for them.
