Adding a sink in the garage.

[Sjsmithjr]

Just for general information and to get back on track a little, with regards to notching the studs for the 2" pipe:

If you did the job neat and accurate, how much should remain of the 2x4 after you notch it to clear a fitting like the elbows in the picture? 4" lumber is nominally 3.5", what would the OD of a 2" fitting be?

OD of 2-inch SCH 40 is 2 3/8 inch. The OD of the socket on the fittings will be 2-5/8 inch. Just saw the pics. From what I can see the OP needs to take the appropriate corrective actions or give his tools to someone that knows how to use them; those walls are at 90 degrees - unless some very creative carpentry took place one of them is taking a vertical load and will fail. How and to what degree that failure manifests itself is anybody's guess.

In addtion to the use of wye where there should be a sanitee, that looks like a vent (short turn) 90 on a drain line which is a no no.

Sharkbites and compression fittings are not the same thing.

You really need to tear it out, repair the damage to the framing, and start over with input from someone that knows what they're doing.

The truth can sometimes be hard to take.

It would probably be a great idea to hire a plumber and a carpenter at this point.

Clean the slate so to speak..

Good luck

On your next project stop by before you screw the pooch so to speak and you might also want to try a little respect to those who are providing FREE info to you on your project.

Edited for clarity

I would leave the wye and 45 in place below the drain for the first lav, next to the dryer vent.
The waste running over for the second lav needs to use fittings with more sweep. They look to be "vent" 90's.
So add some fittings with some sweep on them,
Cut in a combo or wye with 45 closer to the lav outlet, and re-vent back to the first vent.

I can't see below, but if this isn't a slab, and there is a way to plumb under the floor, I would not have run the second lav through the wall.

It does look like a slab though, so that limits that choice without breaking floor. Though breaking the floor would be better.

On slab foundations, I prefer to do most of the plumbing below, and only have a few vertical pipes coming up. Any drilling should be kept to a minimum.
