You will need a 4" to 3" reducer. A 3X3 can work but a major PIA.

I used a 3x3 with no issue. Wasn't the traditional fernco though. This one had some sort of metal brace with 2 hose clamps on the outside. The material is a bit thinner than the fernco and much easier to stretch.

Believe it or not, the stock bellows will work with some persuasion.

That's what I am using, I did heat it up a little to help it stretch.
