You are trying to argue that forcing a gas through a smaller pipe is somehow easier than forcing it through a large pipe.

If that's the case, then why do turbo cars, whose turbos operate off of the delta P before and after the turbine, have huge exhausts? Even more to the point, turbo diesel trucks, which operate in the rpm range we are discussing, come with 3 and 4 inch exhausts from the factory.
