Mantec also has the hard turn, its just located in the fender
Is anyone plumbing their breather lines up the snorkel?

There's nothing wrong with a 90° turn in plumbing when moving fluids as long as you allow for it when calculating the flow.
There will be turbulence caused by the 90, but the straight pipe after it should allow for that to dissipate.
In any case, no matter what type of top you have, you're going to have anywhere from a 90-180 change in direction of flow.

I had my 110 done that way-all breathers terminated under the mushroom cap. pretty cool not to ever have milky oil in difs,tcase etc.
And I love to drive through deep water-foolishly so.

Yes, the bends are way too tight, and that close to the opening eliminates any chance of "Ram air". The airflow backs up right at the throat and spills back out the opening. It's true that there's nothing wrong with a 90° turn as long as you design it properly. But in this case, the radius is too short, and I doubt they calculated the flow and determined the proper intake duct size. They just made it look right. And the Mantec really isn't any bettery in this regard. Sure, it doesn't have a bend per se, but it still has that hood thing which isn't aerodynamic either.
In any case, none of this matters. The airflow through the snorkel has a negligible effect, positive or negative, forwards or backwards. These are not high performance engines by any stretch of the imagination. And the evolution of Dakar trucks shows that the minor reduction in airpressure from a backwards facing intake is more than made up for by the reduction in dust ingestion. And that's on a race that only lasts a few thousand miles. On an overland truck with a lifespan of more than 100,000 miles, and you're not even racing... turn it backwards in dusty conditions. It's a no-brainer.

It doesn't matter what kind of bend it is. Any bend will cause turbulence, some, like a long radius 90, less than others of course. But that's the nature of fluid dynamics and can't be avoided, only mitigated some.
