David any good muffler shop can expand the pipe or the flange to fit they do it everyday

I did some driving around in SA today and nobody said they could expand the flange.  I will have to keep looking some more.

They want to do a butt splice weld.  I'm sure there is a reason Eagle didn't butt splice this fitting when it was built.  I don't feel comfortable with that type of splice.

I have actually been looking at these pages but haven't found one yet. 
Thanks

The flange Eagle used was a Nelson or a Riker, man where is Norris when you need him I looked through some papers and never did find where I bought those flanges or the complete 90 bend

This may work.  No length given.  I will have to call tomorrow

That one won't work.  It is too long on the flare side to the corner and too short on the sleeve side to reach the next exhaust joint.

I need 10" from the flare to the corner and 12" from the corner to the end of the sleeve.

The combo in my following attachments may work.  I can cut the 12" leg and somehow get the flare welded on there.  The other leg with the sleeve is 12" which is perfect. 

The flare in the attachment from United Muffler is 5.63" which is exactly what I have now.  Apparently I have a marmon flare to my turbo pipe.  This is the only 5.63" fitting I've found.  All others have been 5.75 or 5.88.

The challenge is getting a 5"OD flare welded to 5"OD elbow pipe.

BTW-the rebuild price on my turbo is $1300

I don't know why you can't get it butt welded by a competent welder. Scores of piping have been butt welded over the years with no issues. You could also work the end of elbow with a ballpein hammer to enlarge it enough to allow the flange to just enter the pipe a touch. Many exhaust pipes for special applications have pieces butt welded together.

The factory uses butt welds a blacksmith forge weld type I doubt a regular wire weld would hold in the long run 

[chessie4905]

Have it stick welded with a good alloy rod by a certified welder.

I do this for a living. Butt welds properly done will outlast the tubing. ALL Y pipes are basically butt welded. The only way possible. As long as the weld is done by a competent welder it will probably outlast you.
BTW, with the looks of that flare the Vband clamp was probably loose. Make sure you replace it as well.

I enlisted a local welder to attach the flange.  $40 later it was ready to install.  It took lots of grinding, filing, and buffing to get it to seat correctly to the cast iron elbow.  Whew, the whole exhaust assembly is a tight fit all the way to the muffler, but I got it done. 

I followed the startup procedure instructions precisely, and all went well.  The bus ran great.

Beautiful turbo!
I don't have one, so I admire others...
