Good afternoon and evening,
I was reading about the NS method, but it's currently difficult to obtain in the United States. I'm considering the CO2 option... I'm thinking of buying an oxygen mask or a mask for smoking marijuana and modifying it (I would have to cover the mask's filters) to connect it to a hose that would be connected to the car's exhaust pipe... Could you please offer some suggestions or tell me if this is a good plan? (Do you think I wouldn't be able to tolerate the gas until I become unconscious?)

Your body would probably attempt to take the mask off. If your considering CO2 find a enclosed space with no vents (or vents that can be blocked) and run a car in there.

I'd expect gas straight from the exhaust to be both hot and harsh. This method has also presumably become very hard to pull off, since the introduction of catalytic converters.

It's SN, and CO. The latter no longer works unless you have a very old car, because only they still exhaust carbon monoxide, also it's usually done by sitting in the car with the exhaust tubed through a sealed window.

Although the catalytic converter helps reduce some toxic gases such as nitrogen oxides and hydrocarbons, it does not completely eliminate carbon monoxide (CO). If you connect a hose to a vehicle's exhaust pipe and direct it into the car's interior, even with the catalytic converter functioning, carbon monoxide can still enter the vehicle. Therefore, even if the car has a catalytic converter, if a hose is directed into the vehicle's interior, the gas could still accumulate and result in carbon monoxide poisoning, which can be fatal.

Do you think that even if I properly seal the window through which the gas is entering, the car's catalytic converter system won't be sufficient to eliminate the accumulated CO2 concentration?

Isn't CO2 concentration the very thing you feel when you hold your breath?
I believe you'll feel yourself suffocating, and I think that's what has made the method hard.

Well, I read that this is what would actually happen:

If you connect a hose to a car's exhaust pipe, the gas that would enter the vehicle would be primarily carbon monoxide (CO), not carbon dioxide (CO₂). CO is what can be lethal, because we can't detect it with our senses.

The feeling of suffocation or difficulty breathing is a sign that your body is trying to get rid of CO₂ (the gas we produce when we breathe), but carbon monoxide doesn't produce the same sensation. CO doesn't cause that feeling of shortness of breath until it's already at very high concentrations, which makes it much more dangerous, because you can be inhaling it without knowing it, and the damage can be fatal before you realize it.

Final thought :
Okay, I understand now. Well... it's an interesting method. Now I understand why they sent me to the mental hospital for mentioning that method.
