I assumed the leak was coming from the junction of the headers to the mid pipe as so many others have that same leak…

I had taken a rubber hose, and used it as a stethoscope to try to isolate the noise by sticking it around by that junction, and realized it definitely wasn't that.

I could clearly hear it coming from underneath the heat shield on the driver's side, and can only assume it's from the headers at the manifold.

Although perhaps it is the emission valve, and it just finally gave out all the way (or both).

I'll update what I find.
