Isn't there a legal limit on the amount of dB(A) produced by any vehicle?

I would love to see statistics on how many tickets are issued per year for these violations. I suspect zero.

Anecdotally I've heard that they are mostly used as a way to stop riced out Japanese cars.

Not ppl on motorcycles. As someone who has run straight pipes across two major cities never had an issue. A bunch of motorcyclists don't even have licenses lol.

Had a friend who put an Akrapovic on his MT-07 - DB killer is welded but once you drill through a small part on the weld you can remove it/put it back easily and the drill hole is covered by carbon shield so unless they disassemble the shield to check (and my friend had it like this for 5 years before selling IIRC) it was just pull out - put it back in for technical

Just curious, do these changes affect power output in either direction?

Generally, well designed bikes assume a certain pressure in the exhaust pipe and use it as a way to compute the internal combustion cycle timings, since it affects the movement of air and how long it stays and how fast it is likely to move on. So changing the pipes without doing anything indeed affects performance. That’s why most pipe changes usually also come with a reflash of the bike’s ECU so that the onboard computer can know new pipe’s air resistance parameters.

I hear them outside and am happy for them, they don't have tinnitus. Yet. I used to like the sound of engines, still do, but I never understood the farty exhaust tbh.

Yeah it’s just being a nuisance for the sake of it. There was one who lived over the road from me a few years back who would rev his broken exhaust bike at 5am and wake everyone up. About three weeks later his motorcycle mysteriously caught fire in the early evening. There were people smirking out of their windows enjoying the schadenfreude. There’s still a puddle of aluminium melted into the ground where it died.

Sadly this won't help in the majority of cases. Their insurance will just pay for a brand new bike with the newest and noisiest tech installed.

This doesn’t deserve to be downvoted. The statement is correct. I have a permanently destroyed right foot and ankle because someone made a left turn from the right lane just outside the Holland Tunnel in NJ back in 2004. The driver “didn’t see me” before making the illegal turn and planting his Mercedes horizontally across my lane as he slowed to enter the gas station driveway. I laid my quiet 800cc bike down and plo…

It sounds equivalent to driving your car around with the horn constantly pressed for safety. Why not get a horn or something for your bike? Or wouldn’t that sound as cool?

Funny enough, that basically describes traffic in Vietnam.

I'm not commenting either way on the value of loud motorcycles here, but is this related to the article? It says the danger comes from mounting the phone directly to the bike. As far as I can tell, it doesn't say that the acoustic vibrations damage the phone. Would the muffled exhaust also reduce the physical vibrations of the frame?

Judging by the vibrations of my walls: yes. The sooner a maximum noise emitted law for vehicles goes into practice the better. I have a neihgbor here who goes out for small trips 20+ times per day on his HD. Open the garage door, take the bike out (running, of course), close the garage door, rev it a couple of times, wait for a few minutes for the engine to warm up, roar away at maximum volume. Return 10 minutes late…

Noise cancelling headphones can negate it but it could damage a phone? This seems more like the place for people to gather and say "I don't like motorcycles because loud." Which is fine, but let's not really say it's related to the post.

Sounds like someone needs to build an MRAD. You can put out as much noise as he does, and make sure it is very carefully aimed at the only suitable target.

You have a reading comprehension problem. The one situation is where a phone is in very close proximity or even mounted on the bike, the other where there is multiple 10's of meters between my seat the motorcycle, as well as me being inside a house.

He’s a delivery drug dealer. Very common for heroin and a major enabler of the heroin overdose epidemic. Allows people who are too zonked to do anything to still get their fix. Pioneered by Mexicans but now adopted by all kinds of criminal gangs.

That never even crossed my mind.
