The exhaust will increase the hp in the car. Just because it's AT doesn't mean the engine is any different. Remember, the tranny and engine are seperate. Everything one would do to a MT car to increase hp will still increase the hp in a AT car. BTW like your Z. ALso, people are gonna flame the Altezzas on your wife's car.
