Broken stub out: how do I get it out?
Hello my name is Paul and I'm new to the forum. I have very little plumbing experience, but I figured someone here might know how to fix my issue.
I recently purchased a property and need to fix this disaster under the sink. The plumbing is from the 1950-70s. The pipe in the picture is completely rusted and even split down the middle. The metal portion is about 4-6 inches lone and it connect a PVC pipe that goes 90 degrees to the right.
How do I go about removing and replacing the metal portion? It is doable without ripping out more of the wall?
Thanks!

Welcome to the forums.
Bad news Paul.....I don't see how that can be even worked on without opening the wall.
You need to be able to see clearly back to the main stack to see what can be salvaged.
I also moved the thread to plumbing and piping.

Thanks for the reply!
Everything back there looks pristine (it's difficult to see in the pictures), besides the first few inches of pipe. Would it be possible to remove the bad portion without opening the wall? Of course I'd risk breaking the PVC that it's connected to.

Are you saying it's PVC inside the wall ?
It would be extremely rare for that stub out to be into anything other than cast iron.

Yes. I'm positive it's PVC. In pic #1 if you look to the bottom right of the stub out, you can see the white of the PVC. When I look directly into the pipe I can see the white inside of the 90 degree PVC elbow, it's the only part that isn't completely rusted. Past the elbow, it continues to the right with more PVC.
There is nothing right or normal about this house, so I'm not surprised this is out of the ordinary.

That's not so bad.
I doubt it will just spin out....although maybe.
That looks to be inside a vanity or cabinet. I think I'd remove the one tile where the pipe goes thru and work on the stub thru there. You may be able to just peel it out of the fitting. Work carefully to save the plastic fitting threads.

Good idea to remove that single tile. I'll probably do that and then try twisting it out. The PVC goes directly to the right without any support, so I'll probably risk doing damage.

It's difficult to see if it's glued in or screwed in, but I can see what might be glue around the outside where they meet. I just tried my luck at twisting it out, I don't think it's going to happen. The other side of the wall is the laundry room, which would be a cheaper wall to open up and then repair.
A person on another forum suggested taking out the tile on the sink side. It's inside the vanity so it doesn't need to look pretty with tile. I could probably get away with just putting wood similar to the vanity along the back.

If you can remove a tile and get your hand and a wrench in there then fine.
I would cut the sheet-rock on other side large enough to cut the elbow out. Install a new elbow and run pvc right out to the sink.
No more steel/galv pipe.
