We had an island double sink, disposal, dishwasher that worked fine. Since the remodel (new double sink, new plumbing to main cleanout, new dw) we have a glug, glug and gurgling sound after water runs through the pipes from either side of the sink or when the dishwasher is in use. Could the new plumbing configuration cause this? The old main drain had two different connections for each sink but the new configuration has both traps ending into the same pipe, which then T's into the main.

First and foremost is lack of vent at where the two trap arms connect to 4" verticle pipe. An alternate way to plumb the DW drain connection is to have a different tailpiece that has a connection for a dw to connect to.

noise
The glug, glug is caused by the lack of a vent, and nothing will stop it other than providing some method of venting. Even the most inexperienced plumber should have known better than to connect it improperly. A single connection for both sinks will do the same thing, it is a matter of simple physics.

This is how an island sink should be vented.

Here, we would also have to install a cleanout on the vent in the wall in case the horizontal arm were to get plugged up during a backup situation.

The Illinois code itself does not require the clean out on the vents, but most city and county codes do require it.
the original set-up
No vent certainly makes sense, but the interesting part is the original plumbing did not change much, unless there was some kind of vent device removed from somewhere that I don't know about. Here's the original plumbing when the sinks were quiet. Only difference is the old cleanout was cut down and the new elbow/cleanout cap was attached connecting the two sink traps to one pipe instead of the two traps connecting individually.

You might have a partial blockage in the 3" pipe and as the water is trying to drain down you're getting high pressure build up which will cause the drains to gurgle as well.

I believe Mr. Ratz has described exactly what you have...
The drain while not vented properly has not started missbehaving until the blockage made a bad situation worse...
On your next remodeling project that involves any pipes I would advise having a plumber come out to make any needed revisions to the pipes at an early stage of the project. You obviously have some substandard stuff going on there.
