It is leaking at one of the joints. No tune issue. Rear O2's are in front of the secondary cats and only monitor front cat operation.

So if we have a leak in the exhaust system even if it's after the o2 it will throw a code?

usually just if the leak is close to the sensor (which is monitoring the 1st cat). However, it is possible to damage the O2 sensor if it gets too hot during the re-weld. if your exhaust guy hasn't already welded it up, I'd ask if he can remove the O2 sensor when he plugs that leak he's already identified.
