headers flow #s

Looking for some 1 3/4 headers and 3 " off road x pipe. Would like to see some flow rates on them does anyone know where these numbers can be found ? I am looking at Dynatech, American Racing , and Kooks.

Thanks , some good info there. Odd to see my Hooker perform low . Guess a set of other headers could help me.
