i figured it out. this is a rough estimate, depending on exhaust length but its 115 cfm per sqaure inch. by my calculations a 3 inch pipe = 800 cfm. which is about where i need to be.

You can figure the area of 2" pipe, then divide it by the area of a 3" pipe, multiply by 100, and you get the percentage the 2" will flow compared to a 3".
