You are right it has to be tuned, but it shouldnt run rough like that. I waited 2 months before my car got in for a tune after headers. Sounds to me like you have a leak somewhere. I would check the connections at the cats.
Any leak will cause it to run bad.

I've retightened every header bolt and even the clamps where the collectors go. I even thought it was bad gas so I ran the car empty and put half a tank with 100 octane.

You didn't put your spark plugs/O2s back in right or they're broken. I don't see how it could possibly be anything else.

What could cause the random multiple misfire code? I double checked everything and took it back to get the codes read and it said bank 1 and 2 sensor 2 low voltage and not responding and multiple random misfire.

I double checked and tightened the connection to the mid pipes again and the same thing. I heard something about the 13's being really sensitive? Could this be true?

Nothing sensitive about your car. Must have something to do with plugs.

Did you take the plugs out when you did the headers? I've seen a few people try to leave them in and crack a few.. Check the codes, see which cylinder has an issue and check that plug.

Recheck plugs/wires? IDK if it would do anything but have you disconnected the battery to reset the ECU?
