1) Yes it would take longer, but what's coming out of the exhaust isn't perfect. The cat isn't a solve-all issue to global warming and pollution.
2) see above
3) You're right, like I've said though, we are in a very very SMALL minority of vehicles without cat's.
4) I live in east LA and work in long beach. I've seen what the power plants along PCH emit. The footprint 1 factory like that leaves behind in a year far surpasses every cat-less car in LA emits in that same time frame.
5) Keep in mind when saying this, the US has a very strict standard when it comes to factories. As strict as the EPA is on vehicles, they lay down the law when it comes to big factories. What's coming out of our pipes is already many times cleaner than what the factories over seas are producing and IT IS STILL A PROBLEM IN THE STATES. We just aren't clean enough and energy plants are the culprit, not the 1 off hondas with no cat. China is leaps and bounds ahead of us (last I heard on the news) when it comes to clean energy, but that's still decades out in the future when they turn off their old plants.
I'll reiterate my point though, if you daily your vehicle, leave the cat on. Look past the environment stuff for a moment, it honestly sounds like shit (subjective), you gain nothing and you have a hard time passing smog; not worth the headache. However, if it's your weekend car and you like to find the limits of your vehicle then absolutely go for it.

Geography plays a significant role in pollution. California has some of the toughest pollution rules out there, citizens of that state pay a huge cost in taxes, fees, and increased prices for all kinds of goods and yet 8 out of 10 or the worst air quality cities in the USA are located in the Golden State.
Collectively we should feel a responsibility to have a certain sense of stewardship for the environment and what we leave as a legacy but one little deviation is not going to make a hill of beans in the big picture. I don't sweat it when I have a real wood fireplace up to speed in the winter or riding my mower around on the grass.
When I was a kid, science said we needed to worry about the coming ice age. Then there was the population bomb. Then there was acid rain. Then there was global warming. Now it is climate change. Turns out all of those past "crisis points" were based on faulty science. We don't know everything but we do know the world is coming out of an ice age and that means the temperature increases with or without people. There were geologic times before us critters when the temperature increased 2 degrees C a year. (Has to do with chemical oceanic reactions) Don't forget most of the USA was under ice. Warmed up just fine without us folks.
Think of this science (math really): of the top greenhouse gasses carbon dioxide is 3%. Of THAT 3% mankind (USA. India, China, etc) is resposible for 3%. So what is .03 x .03? .0009. That is the number of carbon dioxide mankind is resposible for of the top greenhouse gasses in order down to carbon dioxide. Thinking some gal in Berkeley is saving the planet by conserving a plastic bag for carbon credits is like someone thinking they will affect ocean levels by urinating the Pacific.

One day of volcanic eruption can blow an entire country's efforts at minimizing certain pollutants. The US's energy plants are actually pretty darn clean especiallty considering the cost of fuel. Nuclear is clean once operational but it has a nasty record. Would you rather live downwind of an up to code coal / natural gas power plant or a nuclear one? I will pick dino fuel anyday. Far more people are killed/injured/affected by nuclear than dino plants.

Interesting and entertaining thread.
Im looking to replace my OEM CAT to a TP because the dang thing rattles when i turn off the car.
Any recommendations on the size and brand for the TP?
Also, whats this about the extra soot created by the TP? How much we talking about it and is it enough to damage the bumper?

If you need to save money, buy a used oem cat.

Like stated above, most people recommend Berk, but also from what I've read, there isn't much if any performance gain unless you have other modifications and tune. Also, fwiw, I've never seen a head to head comparison of cat performance, and afaik the OEM is engineered HFC and is not considered a bottleneck. Unlike most cars, the S2000 was engineered with performance in mind and there is not much gained by swapping out OEM parts.
Old thread but a good read imo - https://www.s2ki.com/forums/s2000-mo...-hfc-s-842575/
