Mike your right coming out of the DC it's 5" and the "Y" goes to that then the 2 outlets are 4".Double check your "Y". I think my Harbor Freight machine has a 5 inch inlet that the "Y" connects to. If I remove it, I would need and adapter to connect a 4 inch hose.
You may have the same setup.
Hope this helps.
