I just switched the stock y-pipe for the enfini version. The hose that connects the aluminum y-pipe to the intercooler is about 1/4" too low. There's a rubber coupler at that junction and it is able to compensate for the mismatch, but I assume it will likely fail in the future. Hopefully someone knows the answer:
1) Am I supposed to use a different hose to connect the intercooler?
2) Did I install the intercooler upside-down? It looks symmetric, but I suppose it might not be.
If I have to, I'm sure I can print a new pipe for the intercooler connection and make it 1/4" longer. But that seems like the wrong approach. Any ideas?
Has the turbo ever been dissembled? I’ve seen the same issue after swapping the primary turbo’s CHRA. Alignment of the compressor housing was slightly off. Was able to carefully turn the compressor housing with a rag and a pry bar to lower the y pipe to line up with the inter cooler.

No. I was replacing the old y-pipe because it was leaking but didn't need to touch the turbos.

No support bracket is needed with the bolt-on crossover. Only those crossovers that had a coupler at the Y pipe came with that bracket. Just remove it.
Sidenote: I personally use a properly sized washer with the crossover bolts that came with mine. Probably just OCD but…

It looks like there's a bolt or nut under there, I'd remove the bracket just to be sure. Can't remember exactly, but I think the bracket can be bolted on backwards and also cause issues.
Is your y-pipe fully seated together and bolted to the turbos?
Just trying to think of anything that might make it weird. I think Banzai Racing makes an aftermarket bracket to support the pressure tank. But, it's not strictly necessary.

I looked under there with a camera and nothing is even close to interfering.
Doh! Got sidetracked while reading. I forgot about that bracket supporting the tank when I suggested removing it. But regardless, mine doesn’t interfere with the efini crossover.

If you have ruled out any interference caused by the bracket then I think that leaves you with the alignment of the compressor housing. The bolt on y-pipe is not as forgiving as the stock one as the coupler can adjusted slightly to make it fit (and potentially leak...)
I learned this after rebuilding the turbos and wanting to change the y-pipe afterwards. The new y-pipe would not line up and I though I would have to remove the turbo again to adjust the compressor housing. This was the thread that gave me the idea:
