I plan on installing a new corsa exhaust as soon as available.
Will this change in back pressure effect any of the engine electronics.

I am not sure wether the CTS has precats or not (I think they do), but if you change that it can have an effect on the oxygen sensors, minor though

As long as yuo maintain enough back pressure for the EGR to operate, youll be just fun!

Just as with Corsa's on the Corvette, you add o2 simulators and will experience no problems. Any qualified tuner will know what adjustments to make the Corsa's as natural as stock with a pleasant SOTP performance improvement.

O2 simulators?

Not likely, if I understand what you're suggesting, and if you're referring to the piece that will be sold through GM dealers, since this would be tampering with the OBD-II system and therefore smog-illegal.

Plus I think that OBDII would be able to compensate for it.....

No, it should run just fine straight out of the box. A bit less backpressure, some more noise, and some power.
