Problem installing a modified stock turbo-exhaust manifold up pipes don’t match???

[Big Red 00]

2000 F-250 7.3 – Modified my stock turbo with the following: x-wheel compressor wheel with ATS compressor housing. Garret 38R 1.0 turbine housing. Changed leaking pedestal to a new non-EBPV pedestal with turbine housing downpipe adapter, Banks Big Head wastegate. Put it together, disassembled the lower bolts on the exhaust manifold piping in order to have the slack to fit that exhaust manifold Y pipe to the band clamp on the back of the turbine housing. All good at this point. However when I try to reinstall the exhaust manifold piping they do not match. The angle appears off and there is at least a half inch gap. Perhaps the turbo modifications changed the size slightly enough to make this parts not fit? Do I need custom fit exhaust manifold up-pipes at this point? Any one experience this issue?

you loosened the up pipe to manifold bolts or removed them?
everything should go back fine. when i put new up pipes on i got the turbo in first and then tightened the lower bolts all the way down. their wasnt any gap.
maybe you should try tightening the manifold to up pipe bolts first?

removed them (the bottom ones first, next to the exhaust manifold) ...that clamp in the back of the turbine housing where it meets the up pipes is such a pain, I assembled that union outside the truck, then removed the upper bolts next (where the up pipes mee the Y) so I could get the turbo back in which was fine. Now I'm trying to fit the up pipes between the exhaust manifold joint and the Y joint. Hope that makes sense.

My guess is that the up-pipes are original and therefor probably in rough shape.
The slip on fit of the pipes to the turbo manifold is probably just out of wack and you cant see it because it's too tight back there.

You have to install the y to up pipes first then pull the y to turbo down onto pedistal and put two bolts in finger tight. That clamp for the y to turbo has to be done with the up pipe bolts loose ... its a pain. The up pipes probably just swiveled a little. Everyone does it differently so whatever works. Do yourself a favor and leave the down pipe off until last.
