Whopse. yeah a=piR^2, and i meant rectangular as in rectangular prism.

Actually, that would be a square (not a rectangular) shaped exhaust. Diameter * pi would be the circumfrance. To determine area of the exhaust, you use radius squared * pi. Therefore, the following would be the correct calculations to determine area of the cross section of the pipe:
2 inch piping = 3.14 sq. inches of area of cross section of pipe
2.25 = 3.97
2.5 = 4.91
3 = 7.07
3.5 = 9.62
4.0 = 12.56
EDIT: Nuke beat me.

That would be if you are running a rectangular shaped exhaust.
For area calculations it would be diameter * Pi (3.14159...) or volume=area * legnth of exhaust.

i just want to say this though...exhaust has to do with area which is related to diameter squared
2^2 = 4
2.25^2=5.0625
2.5^2=6.25
3^2=9
3.5^2=12.25
4^2=16
