IMO getting the runners pointed into the turbo is much more important than attempting to get equal or semi-equal lengths.
Also, trying for smooth bends but expecting the gases to make a sharp turn to enter the turbine (see his #1 and #4) is dumb, it's better to go for sharper bends in order to avoid a final, very sharp turn into the turbine.
Lastly, #1 blowing into #4 isn't too bad, because when #1 exhaust valve is open, #4 is always closed. In contrast, when #1 starts to open, #2 is in overlap, the worst possible time for #2 to see a pulse of exhaust backpressure.
This layout looks good to me:
and this one. No attempts at equal length, but gas flow from each cylinder into the turbo is pretty smooth:

FWIW, I think it's great mt'ers are contributing to the discussion. I find discussion on this forum is a bit over my head, so for the novice wrencher lke myself, m.net is great. That said, I have no doubt that constructive feedback from this crowd could improve the products being offered at m.net.

But honestly, if that's all it takes to sell stuff to NC owners, maybe we DO need to arrange something over there.
Start a list with names. Post little info. Shitty products and tell people to follow other manufacturers installation instructions. We'll be rich!

I mean how hard is it to have the welding done properly, correctly size Inconel studs so that you do not tack weld the turbo to the manifold, and remove the gasket between the two. I will give them possibly not having the best designed, because I do know the engine bay constraints in the NC.

Don't think I haven't considered it. I've got weld els in the garage, a flange, and I have the same level of welding skill. I sat here and thought "Hell, I could do that!"
I just don't want to ruin my flange... today.
