Also at least here in NYC aftermarket exhausts are NOT illegal, and there is no code to have your car confiscated for removing your muffler. All you'd get is a ticket for the noise. Remove your cat on the other hand, and you could lose your car.
Also who said a high flow cat or no cat always gives more power??? Ive been on this board a looooong time and seen a ton of info on it. On a NA 4 banger Accord, dropping the cat for a straight pipe, or using a highflow cat will give negligible, no gains or even a loss in power. For the money, time and effort, its a pointless mod even with Headers, Intake and Exhaust.
Ive seen dyno's on 4 cylinders putting out more power than the Accord which LOST HP with a highflow cat, and more with a staright pipe. SCC did a test within the last 2 years that showed the same.

Actually on a turbo eclipse you will get a 15hp-20hp increase with a straight pipe, not sure about NA though.

out of the topic...
how long does the stock cat last? i got a feeling my friends one on his lude is gone...
with a clogged up cat would that give you a O2 sensor code? im pretty sure it would hurt performance in the vtec range... less pull

Gutting out your cat convertor is like having sex in Thailand without a condom. DON'T DO IT. Not only is there no gains, its risky, bad for your health and your Accord ain't the fastest thing even with headers and catback exhaust. I know I have the same setup. So keep your stock cat in. Even an aftermarket high flow cat is a waste of money. You probably will gain only 1 dp at most (DP= donkey power)
