thanks for the quick reply and I apreshiate your info. I am leaning toward doing it now and ill update if I do.

The getting air quicker makes sense in a way. Airflow causes the top spin to work so we are adding drag to the intake process vs. a free flow CAI or stock intake. Probably more accurately we are slowing the increase of air volume to the engine.
Another thought is that these are designed more or less for diesel engines and if there is one thing I have noticed its the way diesels Rev slower than gasoline. Now there's a ton more vacuum behind a diesel as well so that would affect the top spin too.

So the pipes and junk all seem straight forward. This piece is a bit weird with the shape but it sounds like 3" flexible anything will seal up nice. Probably should measure the circumference
or maybe run a silicon elbow through the fender to hook onto the air box itself. The stock elbow is a particularly hash bend. I haven't been in there to look for clearance but I would image it doesn't have to be as bad.
this place sells the silicone couplers, pipes and things. I dont think there price is that great but gives you an idea of whats out there.

stole some more images. looks like keeping the stock elbow is not necessary and with that bend its possibly not desirable.

shows the 3" pvc fittings inside the 3rd gen fender on this custom intake
plenty of room for even PVC.
Wow that's a lot of room in the fender! If I can do it with pvc I might just do this.

Lucky it's all based on 3" pipe and that's common. I've seen aluminum intake pipe, steel exhaust and pvc. Prices are not bad for the amount we need in any of those materials just gotta pick what's going to work the best. I can see pvc shattering from a rock in the cold but I also see that as unlikely. The other two may dent. Steel might rust from the sand blasting it will get in there but it's going to resist denting better.
Use black ABS. It should be better with low temperatures, and actually with high temps as well. You should have no problem finding it in 3" Sch 40, along with all the fittings.

I just read some info that complicates the pvc. To attach the Donaldson you need 3" outside diameter pipe. 3" pvc is actually 3.5" OD. The inner can still be pvc but the stack will have to be metal
What I would do with the stack then is use a step down made out of silicone. I do believe I saw a 3.5 to 3.0 adapter with spectre performance on Amazon and then you would just need a small 2" piece to go from the adapter to the top spin. At least that's one way to skin the cat.

Post up what you find for a diameter of the air box inlet. I'm leaning toward aluminum right now since my tire wont fling rocks that close in with the long travel. Depending on that diameter, I am thinking 3" 90 deg silicone elbow ---> ~2 foot 3" straight pipe ----> 3" silicone hump coupler ---> 3" L shaped pipe. I think the solid L pipe will give me more ways to secure the stack.
