You should be able to use the one off your old turbo can you.
No, they're not even close. The F series trucks' turbo outlets are huuugggge with about 8 bolts holding them in place. The E series' are much smaller and only have three bolts holding them on.

That's because the truck turbo outlet contains the wastegate flapper valve, and the van turbo has no wastegate.
I suspect that the truck outlet causes a lot of turbulence in the exhaust flow, because of the funky shape/volume where it opens up for the wastegate. Instead of flowing smoothly, directly out and into the downpipe, the gases have an opportunity to expand ( and slow down) into that extra volume, and probably tumble and cause a turbulent restrictive flow. All else being EQUAL (which isn't really possible to do), if the truck turbo had an outlet shaped like the van one ( with the wastegate removed) , it would likely flow better.

Is that what the 'high flow' outlet would do? I have heard of it but never knew what it was or did until I started looking at this thing.
