Other than switching the downpipe, do you think there are power gains from the exhaust?

Or to ask it another way, if someone wanted the "stage 2" power with OEM sound, this is possible by changing the downpipe and keeping the OEM cat back exhaust, or are there bottlenecks in the airflow with the OEM exhaust?
