I was just over my buddy's house and I heard some loud gargling noises coming from the basement when his laundry was draining. I went down and looked and I realized it was because the drain coming down gl from his double basin sink was undersized. It was this type of drain, which then stepped down to basically a garden hose. I'm going to change it for him, but my question is, will upgrading to a full 1 1/2 drain assembly alone be enough, or should I also change the drain style to a straight tube down with the second basin leading into the down tube? The water was coming up into the second basin because the inflow was greater than what the garden hose tube could handle.

This is what I was thinking of changing it to.

it could also be because the plumbing might not have proper vents

Just upgrading the diameter should be enough, unless it's a really high flow washer. Don't forget the P-trap (there isn't one in your pic)

It drains straight into a floor drain which, I assume, has a trap of some sort under the floor like my house. Adding a trap won't do any good.

Might as well go for the straight pipe? Cost sould be the same and it might help slightly. Most likey there will be no effect.
I'd also recommend that you make sure the floor drain is free from clogs. Even with proper filters, some lint always gets through to the waste water. Either snake it or if you're lazy, just dump some draino down there.
