I am about to drill my aquarium for a glass.holes 1500 overflow

[Outlaw]

Hello all, so I am about to drill my aquarium for a glass.holes 1500 overflow. It's a 75 gal tank so I was thinking of running 300-350 gal an hour through my sump. My question is as it has 2 1.5" outlets, can I plumb them into a Y fitting to just have one pipe entering the sump? Or would this be too much restriction?

Any opinions welcome!
