If I imagine the restriction of the cat. in "physical" term, the honeycomb of the cat converter seems to have the same structure as 100x 10 Ohm resistor in an electrical circuit, how much resistance? Probably the same resistance as the copper wire itself..
If you try to blow through a pipe with 2 or 3 45degree bends, you may feel some restriction, but if you stuff 30 or 40 straws (drinking straws) in your mouth and blow, it's pretty hard to imagine any restriction..
Probably the only time when you will gain significate hp by removing the cat., is when your cat. has been stuffed with carbon deposits throughout its usage, thus causing the restriction, if the exhaust system is 3 inch I.D. and the cat. is 3.5 inch I.D. the bigger cross section probably already made up for the restriction anyway..
But I think the most important job of the cat. converter is removing the carbon monoxide (CO) which will make you tired, sleepy, headache, and will kill you if the concentration is high enough, so think about what you're breathing when you reverse your car, or when you're stopping in traffic as your exhaust can be blown back inside your car..
