So, TTi says my Hookers are made wrong, are they full of crap?

I just fit up my modified TTi piece and it looks to be a good fit, though I haven't tried putting the X-pipe on it yet.

All I did was rotate the flange about a half inch clockwise, so the axis' (??) of pipe bends seem to be correct. It may in fact be due to Hooker's Hecho En Mexico approach to header building, as the guy at TTi said. So at this point it looks like my question has been answered and they are not full of crap.
