On turning, sometimes, I get a popping noise near the middle of the car on the center passenger side. It isn't a continual popping like a bad cv, just one pop.

It sounds like the exhaust system is loose, you have a broken hanger, and the muffler contacts the undercarriage in certain conditions. I would raise the car up to look underneath using a flashlight.

Can you please shoot a quick video with your phone so I can hear the noise? That way I can tell for sure what's going on. You can upload it here with your response.

This guide can help as well:

No, I do not keep a cell phone. This car also is missing a washer on one of the front sub-frame bushings. Front left.

That can make a popping noise, I would replace the sub member bushings.
