It's possible Danno, but I did notice that I stand corrected on something I said earlier. It does not do it from a cold start, like after sitting all night, just when the car is warmed up to normal operating temps.

Check your lower rad hose after you car has been sitting for a bit. If it is collapsed then that could be your problem. Go to the dealer and get the recall for the rad cap done.

The car never did this before the catback, and nothing under the hood was touched except disconnecting the negative battery terminal for 20 minutes or so, then reconnecting it and letting the car idle for another 20 minutes or so after the catback was installed. Any ideas? Car runs fune too while driving.

if you are still having the same problem, i know exactly what it is. when you disconnect the battery to reset the ecu, then your car will idle strange, once you drive for about 15 miles or so, it should start to idle normal again. i had the same problem when i had disconnected my battery to install my headers.
