Message machine did the trick. This leak has eluded me for the past year or so. Suspected at the EGR since it leaks under boost leak test, but didn't want to just pull the motor to find out. Now at least I know which way to proceed.
Smoke Test
Manifold Leak

I do have a question though, is it normal to have tiny pinhole size leaks at the resonator weld junctions? I assume they probably close up when hot.

You can see the faint white smoke coming out of the back side of the exhaust manifold.

Bought from Guitar Center during their Black Friday sale. Also has a hookup for the boost leak tester.
