not exactly.... the collector diameter and length is usually sized for the reflection of the exhaust pulse (or sound wave) rather than flow, and will often seem a little large. i would wager that a 3" inlet/outlet cat would be more restrictive than a 2.5" pipe... i can take a pic of the cat material tomorrow if ya like awful stuff...
Ed, would you like to share your formulas for those calculations?? i'm very interested to see what would be recommended for my motor.. see how far off i am 
Cya, Stewart
