I would have to 1)see them both installed, 2)compare the costs, 3)compare materials, 4)hear them (preference and muffler pending), and 5)get backpressure data to make an educated decision on that. But 1-4 would probably suffice for the most part. I agree with what you are saying, I just think the flow would have to be pretty substantial to see a remarkable difference.... such that 3" would probably be undersized to begin with.
I would be more concerned with the stock (or even DN precats) before the ATR single shot catback... flow-wise.
