Just a theory but I'm also 100% sure it's true

I’ve seen data from Austria indicating that 70% of vehicles exceeding legal noise levers are motorbikes, 20% are cars, 10% are trucks and busses. Vast majority of loud vehicles are modified in purpose to make more noise.

Also, loud vehicles will not pass annual technical checks so people put in legal exhaust for the check and then put the illegal, loud one in again. This has nothing to do with people not having money to fix their cars/motorbikes and everything with low IQ street racing sub-culture.

I once paid over $400 to put a muffler onto a hatchback that a previous owner had deleted, I must be a fuckin genius.

ExLisper Mar 15

You sure are.

I really like that my car is pretty damn quiet. Especially on start up and crawling speeds, so when parking for example. In every garage the car was in someone told me that they can remove a screw or something from the exhaust, so it’s always open and makes loud noises all the time. They all were pretty perplexed when i told them that i absolutely don’t want that.

If you want a loud exhaust just drill a few holes in it.

It’ll be loud af.

Related: “A new study by Western University in Ontario says that if you’ve got a car with a modified exhaust system, odds are you’re a guy and probably also psychotic and sadistic.”

Study Says That People Who Like Loud Exhaust Are Psychotic

The study made some strong remarks about the kind of people who would modify their car's exhaust.

A few (major) caveats:

(edit: I previously misread the author’s information; she does work at UWO)

The study is being filtered through a blog post.
The study itself is written by one author and published in a journal by the University of Gdańsk of little import. That’s, of course, just an indicator it might not be the most credible.
I will defend psychology as a science until I’m blue in the face, but it is right now undergoing a serious replication crisis, especially because of its poorly representative sampling.
The sample is: “A sample of 529 (52% men) undergraduate business students”, which is a laughably biased sample compared to a global population. They never say which university, but given the publication and the author’s workplace, it’s safe to revise that to “529 (52% men) undergraduate business students at U. Gdańsk the University of Western Ontario”.
The study evaluates negative personality traits based off a “dark tetrad”, which is a still-controversial extension of the “dark triad”.
As the author notes, the mean score from the three questions pertaining to “I want to fuck my car” wasn’t all that high (approximate total average of “somewhat disagree” on all three with approximate total standard deviation of a single additional “neither agree nor disagree”). This means the actual sample of people who had the problem being addressed in the title of the study was vanishingly small.

This, to me, is flimsy evidence at best even when I already buy into the basic premise.

A desire for a loud car with a modified muffler is predicted by being a man and higher scores on psychopathy and sadism

Background: Although people are familiar with loud automobiles, equipped with modified mufflers to increase the volume, it is unclear who is most attracted to these vehicles. Participants and procedure: A sample of 529 (52% men) undergraduate business students were surveyed and were asked if...

Thank you for this! I was not familiar with all these shortcomings when I shared that study. I will not share it in the future.

FlowerFan Mar 15

Not true. I don’t have a modified exhaust system.

this whole post should be in fuck_motorbikes

cub Gucci Mar 15

We’re on the exponential curve my mates

I would think logarithmic given that one of the units is dB

cub Gucci Mar 16

Do you really want to get into an argument whether they are the same or not

homoludens Mar 15

You don’t have to be a genius to have emoathy. Fun fact: most people only use 10 % of their heart.

moonshadow Mar 15

My car’s loud cause I’m poor and exhaust parts are expensive. It’s stinky inside sometimes too, probably not helping with the IQ thing. Guarantee it bothers me more than it does you

ExLisper Mar 15

Modified exhausts are way louder than simply broken ones. Maybe 1% of loud cars I see are old and beaten up. In vast majority of cases someone paid extra to install custom exhaust.

moonshadow Mar 15

I think you must live in a nicer area than I do lol. There’s like two guys with fart cannon Subarus, probably five with straight piped pickups, and uncountable beaters with soup cans/tin foil/hose clamps/rtv/bailing wire doing their best. We have cheap power and everyone wants electric but no one can afford it. There is exactly one Nissan Leaf owned by the school district superintendent. My car was $700 including all the parts to fix it. That’s pretty typical here. Cheapest exhaust I could fit was $800 alone when I looked into it, and almost certainly more now.

ExLisper Mar 15

Probably difference between USA and Europe. In Europe beat up cars will not pass technical checks. To have a really loud car you have to replace the exhaust for the check and then install the custom one again. Only special kind of drivers have the time and will to do it. Mostly bikers.

moonshadow Mar 15

Makes sense. The sheer excess of keeping two fully functional exhaust setups around so you can legally run one that’s more obnoxious is definitely infuriating

netweirdo Mar 15

That actually probably explains why bikers do it the most since there it seems like on most bikes the swap can be done in less than 30 minutes as the exhaust system is small and self-contained and easily accessible

AlligatorBlizzard Mar 16

Motorcyclists also believe a loud exhaust makes them more visible to drivers - to what degree this is true is debatable but sometimes the motivation is not pure malice like with cars.

ExLisper Mar 16

I think this is pure BS and trying to excuse stupid behavior. Never in my life did I ever hear an approaching motorbike, no matter how loud. Cars are well isolated, you have noise from the tires, some radio or music is usually playing or you’re talking to someone. Outside noises are barely noticeable. I can only hear the loud bikes when they are right next to me, not when they are approaching.

nothingworked Mar 15

you simply don’t understand

Foofighter Mar 15

I drive an EV, so I’m super smart! /s

Even more so if it does not make any additional artificial sound!

cRazi_man Mar 15

I wanted to be high IQ on this graph so I started walking everywhere. But I still have noisy exhaust.

deadymouse Mar 15

In the next stage, you can gradually increase and decrease your speed, switching from walking to running and back again if you want.

Stop eating Chipotle

Do kegels

AItoothbrush Mar 15

I mean this is especially valid if you look at measured exhaust noise. Many people have cars that CAN make a lot of sound(if they use it for racing for example) but CHOOSE not to make a lot of sound to not ruin peoples days. The one big problem with this is that cheap motorbikes, which is something you would 100% use because theres no better public transit alternative, are also really loud.

Doesn’t apply to some rockets. NASA vs Space Sex rockets.

DavidDoesLemmy Mar 16

I don’t think dB is a linear scale, so it would be weird if it increases in step with IQ dropping.

ExLisper Mar 16

The IQ drop is also non-linear.

phutatorius Mar 16

As sound pressure levels increase exponentially, perceived loudness increases linearly. That’s why the dB is used.

CH3DD4R_G0B-L1N Mar 16

There is a house in my neighborhood with your picturesque McMansion short king that has a white Chevy Tahoe with the loud muffler setup! As annoying as it is on performance cars, I kinda get it. But in a family SUV? Dumbest thing I’ve ever seen. And he revs it in front of middle school kids waiting for the bus to boot. What a sad little man.

Yea well those performance cars are also not street legal lol

Though I see a reason in there

If it’s on an SUV… Fuck off with your loud shit bro.

Also just loudness is nasty. The sound itself must be nice. If it’s not an H pipe I don’t want to hear that shit.

Deleting cats can be illegal depending on state but trust me there are plenty of legal, loud exhausts

Well I guess it depends on the area. Afaik, in Romania where I live, if it goes over a certain db count at a certain RPM it’s illegal no matter what.

MonkderVierte Mar 16

I’d say it’s a curve.

Sasquatch Mar 16

This could be log scale. Or inverse log idk which way you want the curve to be

MonkderVierte Mar 16

BenjiRenji Mar 16

dB is already log scale

Sasquatch Mar 16

Boring response: I mean, dB is calculated as a function of log, but when it’s on the X axis I imagine it’s typically displayed linearly

Funny response: loglog

BenjiRenji Mar 17

Loglog is what came to my mind as well.

Jerkface (any/all)Mar 17

meanwhile IQ is not linear or log

BenjiRenji Mar 18

True. It’s a Z-score measuring deviation from the mean. A step of one point somewhere on the scale just makes a statement about the relative rareity and not about a set amount of “intelligence” you have more or less than someone else.

Sound is annoying but exhaust in general sucks. One thing that was amazing around april or may of 2020 was how clean the air smelt for a brief time.

2021 was a cyclist’s dream. Clean air and no cars

HubertManne Mar 20

and everyone was instructed to give you at least 10 feet of distance :)

Australia, so 2m, but yeah

We were not allowed out except for a few exceptions, one of which was an hour a day of outdoor exercise

I would commute by bike to my preferred exercise location an hour away, ride for exercise for an hour, then commute by bike home again
