Loud exhausts are a social issue that needs to be addressed by the community, not armed law enforcement. Talk to them/their parents/their neighborhood if you feel like it's disturbing you. Fire trucks and ambulances will regularly do much more damage to your hearing than the occasional ******** with straight pipes. I encounter emergency vehicles several times every day but never cars that are louder than those sirens.

Ambulance sirens are like 110db but these measurements are meaningless because of distance and other variables. This post is already too long, loud exhausts aren't a threat to your well being, but cops are.

 

Emergency vehicle sirens serve a purpose. You can try and talk people out of their life choices all you want, but they can tell you to **** off and nothing you can do about that. That's why we have to have laws. To your argument, how are you qualified to say whats causing more harm to more people? Not to be rude or anything but are you a doctor or researcher on this topic or something?

 

If people can smoke in public ,I can have an exhaust over 85dB, if it's a health issue..
we measured our cars the other day. My friend's STOCK Camaro is at 101dB. I guess he better do something about that before he kills someone.

​​​Or maybe we should ban everything that bothers everyone. I have a list I can submit LOL.

 

Hearing damage "can" start at 85db, it depends on the duration of the exposure to level of sound. As db goes, the time of exposure to cuase hearing damage goes down. But keep in mind, a car exhaust that is 105db at the test distance (like 2ft from the tail pipe) is not 105db at 50ft. Sound decrease by approximately 6db every time you double the distance. So 105db at 2ft away is ~87db at 24ft. You're not damaging anyones hearing but your own having a loud car. My Evo with barely a muffler and the O2 dump was like 102-103db.

 

im totally open to changing the law, im just arguing for the governments right to have a law in the first place. If they based the law on bad data then we should fix it with good data.

 

Eh, sound design, not indepth acoustics or anything, but I follow some hearing loss prevention groups. Basically if it makes you cringe and squirm then it's loud. Ambulance and firetruck drivers are supposed to wear hearing protection, even though many don't. It just depends where, for how long, and the environment/reflections. Like shooting the same caliber with a muzzle crown outdoors vs. with a muzzle brake indoors.

I don't think I've ever encountered a car as loud as straight pipe motorcycles. There's a lot of lambos around here with exhaust cutouts, but even when they're screaming at night they're still not much louder indoors than a particularly violent and wet fart. I just don't see this as an issue that someone with a gun needs to be involved in.

 

Actually there is talk about how outdated the testing procedure is, yet they are still using it.
It would be nice to have it updated.
I.E. My friend's Atom passes because he's only required to rev to 3k rpm, Yet I failed. Something wrong with that.

 

Man, my Bug would fail at idle from 15ft away.... Once again, glad its not registered in CA.

 

Thanks for the background, and I completely agree that Law enforcement is overburdened. I do see CHP pulling over loud motorcylces so it's not like they aren't feeling it. The flip side though is what some other countries have, which is yearly inspections.

 

Its probably hard to find a bureaucrat to champion that cause. Once enough money starts to care about it something might happen. Unfortunately I think its only going to go the other way and the laws will become stricter. There seem to be loopholes in every system, and your friend sounds like he is using one.

 

you can clap right next to someone's ear hard enough to blow out their hearing, it's completely distance dependent.

the numbers details are tricky, the spirit of the law is don't run ****ing straight pipes on your car and do WOT pulls in neighborhoods. again, this has always been the law - the difference is now a fix it ticket vs a steep fine. without a steep fine, no one cared. i *think* oem exhausts are exempt - this is for modified exhausts, not stock exhausts.

^ not sure if the above is true, only source i saw that said it.

btw, every state has some kind of exhaust law, some with much vaguer language (aka, completely up to co's discretion): https://www.semasan.com/resources/ex...ise-laws-state

 

His car has a kit car exemption. Pink slip says it it's a 1968 something or other. Different testing parameters. Lucky.

​​​​​id be okay if they were enforcing the spirit of the law. Some are taking advantage to raise revenue.

Good luck convincing them your exhaust is stock. When they were popping hoods in my town, they literally admitted they didn't know what they were looking at and would write the ticket then let the judge/ref figure it out.
they have the same discretion here.

 

No, you do that by smacking your open hand over their ear (so your palm lands over their ear). Not by clapping your hands next to their ear as if you were giving applause.

 

On a more productive note: Just confirmed with ETS that they're waiting on CARB to approve their new intake for the Evo 8/9. I'm definitely picking that up once it happens, especially if it's in wrinkle black unlike the AEM intake. Maybe go send them some words of encouragement.

I got an RRE Stealth, but what the hell am I going to do about this test pipe? Has the rally cat ever fooled anyone? Wish I could fit an OEM-like heatshield to a resonated test pipe.

 

I've done this before. You can drill the oem heat shield off the evo stock cat and have the top side welded to your resonated test pipe. The bottom side can be bolted in place by drilling 4 holes into the top heat shield where the spot welds used to be. If you just bolt it on and rely on the pressure of the metal, it will rattle. It looks like an oem cat even though it's a 3" TP
