Summer is coming, Whole House Fan

I am adding whole house fans and to reduce the noise I am ducting the air from the intake register to the 2 fans 15' away in the attic. I intend to connect the intake register to the fans via 2 x 14" flexible duct. I need to make 2 x 45 deg turns on each fan. Airflow is 1600 cfm/fan. Is this going to reduce my airflow in any significant way?. Obviously I want max airflow.

Thanks to the group.

Might want to check, what static pressure the fans are able to work against.

Will each fan have its own back draft damper. They each need their own.

Don't have the fan so large that it steals combustion air from gas-burning appliances in your house.
