Well you seem to not understand the concept & design here.

Dual exhaust pipes would be smaller in diameter than a single pipe exhaust setup or subsequent "quasi-dual"

For instance 2" duals versus 2.5" single piping...

In this comparison the duals have ~28% more flow volume, but being smaller piping they would achieve higher exhaust velocity versus single piping because the exhaust is expulsed in pulses. Not total volume.

There has been a couple great threads about this in the last month or so. You should search them out.
