How much room do you have to get to the trap? Nibco makes a 2" tubular trap adapter Model # C4801-7, available at HD. You'd need either a brass nipple (cut off the outer end) and a stub of pvc along with a nohub connector. This is if you wanted to use 2" tubular after this. I'm sure there are other ways to piece this together.

A kitchen sink is normally plumbed with a 1-1/2" trap and trap arm into a 2" drain.
This is where I get confused. My plumber neighbor tells me that kitchen sinks are 2 inch traps and the only part that is 1 1/2 is the tailpiece that goes to the sink. We live in NYC. Not sure if this is local code. Also not too sure how much I trust his judgement so I'm here trying to make sure. Thanks again.

I cannot speak for any local codes in a place like NYC.
Maybe you should go look under your neighbor's sink.

I'm alil offended by the way you speak of NYC. Jk. This is what my neighbor/plumber recommends: Thread a new 2" galv nipple into the tee and cut off the other threaded end. Install a mission style coupling on the cut end of the nipple and put a piece of 2" pvc out of the other side of the coupling. Then install a union style trap and switch over to 1 1/2 tubular for the sink tailpiece. How this this setup sound? Thanks.

That's what I suggested, except I'd rather not use galvanized. What you had rusted out...why replace it with something that will again? Brass or SS will cost more, but then the fact you don't have to redo it is worth something.
Yes Jim I would have rather used brass but I couldn't find a 2" one locally. Would I be better off using a male pvc adapter threaded into the tee and then just solvent weld a pvc stub and go right to the trap with that? The only drawback I see with that option is that without the mission coupling I wouldn't be able to take the drain apart easily.

If you have enough room, you don't have to solvent weld the whole thing...you can still use a nohub if you wish to make disassembly easier. Normally, that doesn't happen until the next remodel, though. PVC threaded fittings are not considered the strongest thing. That being said, I've used them successfully. A pro would have more exposure and have more thoughts on this.

I would use the galvanized nipple before I would a plastic one. People can be abusive in jamming stuff into their cabinets, and the plastic would be the weakest point.
