Dangers of Test Pipe?
You sit in a closed garage with a minivan with a cat and you'll still die from it. It's not a light switch that instantly makes your exhaust expel sunshine and rainbows. Yes, in the mass having a cat DOES help. Being the one of the rare cars without it won't save the world. I'd be willing to bet close to 99% of the cars in the US have cat's. You're not harming a god damn thing with a test pipe and you aren't saving the trees by having one.
Places like China, Indonesia, India, Phillipines, etc. all have factories that expel so much more toxic fumes than a group of cat-less car's can in a century.
Honestly, there are better things you can do to help the planet than 1 car with a cat if that's what anyone is worried about.
Don't get me wrong here, as I'm sure someone will take this reply incorrectly, you should have a cat on your car especially if it's your daily. You are hurting the environment and you are a contributing factor to global warming. But in the grand scheme of things, there are dozens of other reasons why our ozone is going to crap but the few car enthusiasts littered throughout the world running cat-less isn't the leading cause of it.

Ehhhhhh....Some counter points:
1.) A good working, modern OBD2 car running in a garage would take a fairly long time to kill you.
2.) A de-catted car would kill you faster.
3.) There isn't just ONE car in the world.
6.) You likely don't live in a city. Imagine LA or NYC or Chicago rush hour with today's population and the amount of cars that result from it. The cities that were cited as having pollution problems also have very dense populations.
6.) The US also has factories.
I agree that you should be more responsible than to use a TP on a daily driven car. And that maybe the population of people who remove their cats as part of an enthusiast hobby are very small.
I drove my S2000 like....2K miles this year. I didn't bother to swap the cat on between track days (this year). It likely makes me a bad person overall.
I get not replacing a broken cat if you don't have to for the money save, but you can't deny the physics of IC engines.

I have CAT's on all my cars, but I'd be hard press to pay big $$$ to replace them if they went bad.
A new OEM factory CAT's were $1800 on my 97 BMW. No thanks.
Sounds like some of you guys need to just up and sell your S2K's if you are that concerned about CO2 pollution. Walk, ride a bike, or buy a hybrid if you have to drive.

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.
EDIT: I don't mean to come off combative and I understand your point, you aren't exactly standing up for the "CAT YOUR CAR OR DIE" cause some of the people play. I'm partly just taking out my frustration out on your post because it was the closest thing to it.

The fumes have gotten to your head. I have a high-flow cat on mine and I can smell the additional unburnt exhaust fumes, even from being inside the car.
Also, OP ghosted this thread because it got too heavy.
His mindset was like..."I know this will make people argue. But...will I be ok?"
