A lot of Americans take their cat off on purpose for louder noises. Additionally, a lot of conservatives love to "Roll coal", and literally will shit up the environment on purpose just because they feel schadenfreude from pissing of an environmentalist.

I’ve run into a few of those. They’re generally pretty obvious. Usually a big truck, lots of MAGA & adjacent bumper stickers. I haven’t noticed people removing the catalytic converters just for noise. The rare time I see a car that wants to be loud it usually just seems to be the exhaust end they changed, or maybe removed the muffler. The kind of stuff I’m complaining about mostly seems to be older cars, or those in poor mechanical shape. Cases where the people probably just don’t have the money to fix it.

> A lot of Americans take their cat off on purpose for louder noises. Some people remove catalytic converters when they install a performance exhaust. Nobody is doing it for louder noises because the muffler portion is what dampens the sound. Also I wouldn’t say it’s “a lot of Americans”. We have emissions inspections in most major cities and your car won’t pass if you remove the catalytic converter. They can now detect modified ECUs, too. Someone would have to be so determined to do this that they’d swap the exhaust in and out every time they had to do emissions inspections.

  I know a LOT of people personally who swap their exhaust in and out just for emissions inspections. That's the meta.

    a lot of people have custom exhausts, particularly catback systems that don't affect emissions. A lot of people are definitely not rolling coal.

      Yeah, it's definitely a small percent of people. But i do wonder how many there really has to be to have an outsized effect. One of those lifted kid killers blowing black smoke for the entire duration of the bicycle pack is definitely more than 3 of my tiny honda civics, i wonder how many it really is, and how much those modifications increase the "resting emissions rate"even when not blowing shit. Should be illegal, likely is.

        I'd wager it's largely disruptive and dangerous in a highly localized way due to the small percentage of folks doing it. Doesn't make it an acceptable practice though. One person "rolling coal" can temporarily blind 3 or 4 cars back and several across depending on wind conditions, etc.

        In terms of NOX it can be a factor of 100. If 1% drive without cats they produce half the NOX emissions. In reality it is probably less since there are other old cars as well that have higher emissions

      I live in a progressive state and unfortunately encounter "coal rolling" regularly. I also assume that's the point. Someone has to "own all the libs" as it were However, I do agree that there aren't enough folks "rolling coal" in aggregate to really move any needles on planet-scale environmental impacts though. Just VERY unpleasant to be caught behind.

        Conservatives seem to be largely unaware that most libs already have an owner and don't need any further owning.

    The internet classic “I know a lot of people” does not substitute for your original “A lot of Americans” claim You’re describing your small friend group, not Americans in general.

      You got ratioed. I’m way up in upvotes from Americans who know that I’m right and you’re wrong! Na na na na na na! Sometimes the plural of anecdote really is data.

    I had downvotes on this post until you (and the other car enthusiasts) pointed this out / saw this. HNs lack of knowledge around cars is sort of frightening.

      Don't worry, it's just cars. You can trust the rest.
    - Aurornis 9mo ago
      If I had to guess, the downvotes were from the “A lot of Americans” claim > HNs lack of knowledge around cars is sort of frightening. I actually have a lot of knowledge and experience in the automotive space, including with exhaust systems! Catalytic converter removal alone doesn’t have a big change exhaust tone. I have seen it first hand, and also with 100-cell and 200-cell race cats as an intermediary step. Your posts are full of condescending assumptions about Americans and HN’s comments about cars, but you’re ignoring the actual facts others are trying to share.

    They muffle slightly, but removing the cat alone isn’t going to make a big difference with modern high efficiency single cat exhausts. I’ve seen (heard) the effects first hand. Trust me, people aren’t removing the cat just to make their car annoyingly loud. If they are, they’re going to be disappointed.
