I think this entire thread is too funny. 
The people who dont use cats are not going to convince the people that do use them and strongly believe you should leave them alone to switch or vice versa.
I have a test pipe and I speed. Not all the time, but when there is little to no traffic I do drive above the posted limit.
I will not make excuses for my actions nor do I feel the need to. If I get cited and pay a fine then thats what I get.
I just think its funny to go into a car enthusiast type forum and try to promote the idea to give up some horse power and put the cat back on. I mean cut and paste the OG post into a Vette forum, Subie forum, Evo Forum etc, etc. and see what types of responses you get.
Everyone here is free to say what ever they wish, you can like me or hate me, but the responses that you are getting that sway towards HP over Emissions should have been expected.
If you want to post things like this that sway more towards the environment try posting it in an evironmental type forum.

i personally drive 50mph in 45mph sections, 30mph in 25mph section, 75mph on freeways usually limted to 65mph on a regular basis. however, when the highway/road is an empty, long stretch of asphalt, i go to about 120mph or so=P.
my brother's old mr2 turbo was catless, and now his EVO9 is catless. the moment he parks his car in the garage and leaves the turbo timer running, the smell fills up the garage quickly and i find it hard to breath myself. my brother even joked a couple times saying he thinks he'll die early from smelling this everyday. you can smell it while your driving slowly or when you're parked. iono but i find it easier to resist running catless if you're N/A.. but if you're turbo, which means you can free up to 20whp just by running catless... i guess there's trade offs to everything..
just my take on it. =P drive safe out there.

I am so sick of this kind of utter nonsense. 
Your claim might be true for a bolt on mod S2000 or even Civic, however my turbo S2000 that is basically become a track car boosting 14psi gains big horsepower without a cat.
Don't make assumptions that everyone that does this has the same result or does it for the same reasons. Not all of us daily drive our cars or run around catless without forced induction making a "couple of horsepower" knowingly destroying our planet.

If you can spend thousands of dollars on a turbo and all the test and setup time, etc., why can't you buy and install a cat that is sized for the turbo? Cars with an OEM turbo have cats.
My car is mostly a track car. It's a 2004 with 10K miles on it!
Like most race cars, I gain a performance advantage running an open exhaust.

Emissions controls didn't come about unitl the mid 1960's.
I guess my parents should be long dead because they had to inhale all those toxic, horrible, earth destroying exhaust fumes.
I'll be sure to tell them that when we go out to dinner with my kids this weekend.

Does it have a license plate?
And you know, you didn't answer the question. Is there any reason why you can't have a higher-flow cat on your car?

And so do tens of thousands of cars that are driven far more miles every year compared my garage queen, that burn oil and pollute more than my S2000 ever will.
And yes, adding a cat of any kind, even the BS "high-flow" cats that basically do nothing more than fool the police would have an impact on the performance of the car.

Hey Mike, what do you think of this below?
-------------------------------------------
Criticisms of catalytic converters
Catalytic converters have proven to be reliable devices and have been successful in reducing noxious tailpipe emissions.
However, they have two adverse environmental impacts in use (ignoring the pollution caused in their manufacture, which would not exist were they not mandated):
The requirement for the engine to run at the stoichiometric point means fuel economy is not as good as that of a "lean burn" engine running at a mixture of 20:1 or weaker. This increases the rate at which fossil fuel resources are consumed and the carbon dioxide emissions of the vehicle.
Catalytic converters are estimated to account for 50% of total nitrous oxide (dinitrogen oxide, 'laughing gas') emissions to atmosphere. While N2O emissions in these concentrations are not harmful to human health, it is a potent greenhouse gas, accounting for around 7% of the overall greenhouse effect despite its small concentration in the atmosphere.
Therefore one conclusion is that catalysts have reduced toxic emissions and the incidence of smog at the expense of increased global warming.
