Nvm about the wye fitting, I looked it up.
Why is it better than the T?
If you use a Wye and a 45* angle instead of a T, it softens the turn on your drain line and minimizes the reduction in flow. Between that and the oversized piping it's probably a bit like a wearing a belt and suspenders but it gives me a bit more peace of mind.
