Car Exhaust Diameter Flow Question

Salutations
We are having a debate on an automotive forum about optimizing flow rates from a turbocharged car exhaust and have not been getting anywhere. I come here for help in shedding some light on the debate. I am under the impression that the car exhaust will flow best when not to small and not too big in diameter. That the pipe size should be optimized to a specific size for best power because there is an exhaust gas velocity that should not be exceeded.
The other party insists that there can not be a too big of a diameter pipe for creating best power results from the engine. The other party also posted one of your flow calculators the air pressure drop calculators to try prove that larger is better because there is a higher rate of flow.
I am curious if there may potentially be other variables at work in the turbo exhaust that we are not looking at or are being accounted for with the calculator. And I would very much appreciate any other insight that may be available that may help us resolve our debate
