This was a very wide reaching bill that covered many different areas. The area pertaining to vehicle equipment violations is also very general and it makes no specific mention of exhaust noise. This bill appears to change the enforcement approach to such violations but nothing in it indicates, at least to me,  any increased attention towards exhaust noise.

The piece of it that I see related to noise is that it says that the muffler must prevent any “excessive or unusual noise”. Our cars are pretty excessive when I hear them in comparison to other cars around (yeah, we all boast of it too, such as waking our neighbors, setting off car alarms, etc.). So it seems we are pretty excessive in the noise department, well maybe not if we keep RPMs under 2,000. Tesla Pantera next?

Here we have always had noise restrictions but the way it is enforced to be anything but a nuisance to a court would require the accuser to produce scientific data showing that the noise producer exceed the legal level.

The noise measuring equipment is in very limited supply. Usually one device for each law enforcement jurisdiction is what is observed. That doesn't even consider that it is 10 years old, has never been calibrated and no one knows exactly where it is at any given moment.

Since noise enforcement is also involved in house parties with live bands, illegal use of fire works, landscape equipment like hurricane leaf blowers and commercial lawn mowers, there is a lack of will by the law enforcement authorities to enforce.

We also have low flying commercial jet aircraft illegally below the minimum altitudes as well as trains in the distance.

The motorcycles late at night running flat out up to 14 or 15,000 rpm in top gear with open exhausts are also in the mix.

Enforcement locally would just be involved with what the pet peeve of the day would be and you'd just have to be in the wrong place at the wrong time and just be poking the lion with a stick at the zoo? The odds of that are very low but hey, someone always wins the Power Ball regardless of the odds?

I've seen Police show up at local "bike club" meets and tell the owners "its sounds a little loud" with just warnings, etc, but they seem to be more concerned in looking for "outstanding warrants". So here at least, nothing is likely to change anytime soon. Don't go driving around with a "motorcycle club", don't go racing them flat out late at night, don't go reving the engine to 7,000 rpm in a "Hospital zone" and you are most likely going to be ok?

I read on another forum this is a big concern, validated by the cop in the video saying they had a  grant and are hitting it hard, so not a rational means to stop the odd offender, but an all effort to control and rake in dollars. It seems just and arbitrary rule, with no basis of test for dB at a certain distance etc. I guess my annual pilgrimage to Monterey may be coming to an end....

Yes, it seems it’s based on the officers opinion of excessive or unusual noise level. Just like when an officer gives you a ticket for running a light or doing a rolling right turn stop, etc. It’s their opinion you did so, they don’t need to show proof.

Here is what SEMA had to say about it:

 

California Exhaust Noise Bill Goes into Effect

California Assembly Bill (A.B.) 1824, which was signed into law by then-Governor Jerry Brown in June of 2018 went into effect on January 1, 2019. The bill has generated significant concern amongst the online enthusiast community. Despite what is being circulated, enactment of A.B. 1824 does not change existing laws pertaining to exhaust noise or sale and installation of aftermarket exhaust systems.

Under existing law, exhaust systems installed on motor vehicles with a manufacturer’s gross vehicle weight rating of less than 6,000 pounds, other than motorcycles, may not exceed a sound level of 95-decibels when tested under Society of Automotive Engineers (SAE) test procedure J1169 (May 1998). This was not changed by A.B. 1824.

A.B. 1824 amended how excess exhaust noise violations are handled by law enforcement. Beginning this year, a vehicle cited for violating the current exhaust noise law will no longer receive what is known as a “fix-it” ticket. Instead, violations will result in an immediate fine.

Consumers in receipt of a violation still have the option of seeking a certificate of compliance from the California Bureau of Automotive Repair (BAR) demonstrating that their exhaust emits no more than 95-decibels. This SEMA-sponsored program allows courts to dismiss citations for exhaust systems that have been tested and for which a certificate of compliance has been issued.

Is this a valid summary?

1) Law allows a citation based upon the LE opinion

2) Have to pay $1000 fine.

3) the cited car CAN be taken to an approved independant shop that can measure the noise levels and provide a certificate.  No mention for this fee

4) you have to got court, pay court cost and no mention if you get your $1000 back

5) the sponsor of the law owns this testing shops

Yeah now it’s cha-ching cha-ching!! I expect to get pulled over through Newport/Laguna/Huntington, not sure about anyone else. Maybe Home Depot has decibel meters to see what happens under load. I can hear most Panteras about half mile away.

Laguna get's pretty serious with enforcement, especially in the summer time. I have seen them drive along side bikes stuck in traffic, stick the dB meter out the window of the cruiser and check the levels right there, without executing a stop. Also there are local ordinances for hefty fines. 

As far as I know, in most european countries a car is legal if it has the exhaust system with which it received its original type approval. If the rules become more stringent over the years they do not apply to older cars. Grandfather rights come into effect. If you modify your exhaust you are fair game. I find this a fair rule.

My newly revitalized Pantera is very loud, but nothing illegal in the State of California was added to it.  So, if the state is allowing the sale of the exhausts, the headers, the engine, etc. and reaping sales tax rewards from those sales, then they had better start banning lots of products.  Jaguar F-types, Lambos of all persuasions, and many other "factory" built cars will exceed those decibel limits on a regular basis.  Thank goodness,  Moonbeam Jerry Brown is termed out.  He won't be able to do any more harm.

I have acquaintances who are members of LAPD, LA Sheriffs, Ventura Sheriffs, and Ventura PD. They have other things to do rather than enforce the vehicle code. That's normally the bailiwick of the CHP.

You guys complaining of enforcement in the Newport/Laguna/Huntington area, I'm curious is that CHP, Orange County Sheriffs, or local police?

Yeah you’re right about Lambos & others with louder than “the norm” aka “unusual” exhaust noise. When taking my LP640 through Newport I usually get an escort tagging along a quarter mile back. I try and shift at 1,200 RPM which seems to help a little. Sixth gear at 40 MPH is a little challenging and not that much fun. Panteras are no doubt louder than my Lambo. I think I’ll just go back to hiding in my garage with car polish. It’s just not that pleasurable driving anymore.

Yeah but all the CA crap is somewhat balanced with the ocean coast and pretty good weather year round, then you have the beach thongs as well. Seems I will eventually have to convert to a Tesla though. Had my Panteras out yesterday all paranoid when I saw the gumshoes around. Shifted at 1,000 with those so they didn’t sound too unusual, although the cars bucked a bit shifting like that.

Arizona may not be looking better.  Years ago in Phoenix I was driving a stock Torino Cobra and had just had the muffler replaced a couple of weeks earlier.  I was cited for a noise violation.  I went to court and the judge explained to me that Phoenix has no decibel limit and if you are cited for excessive noise then you are automatically guilty because it is the officers judgement.  Same reason lawyers advise you not to take a roadside sobriety test.   I got off without a fine because I could show the dated receipt from MIdas for the muffler installation two weeks prior to the stop.  Last I heard Phoenix also has the "exhibition of power" law where you don't have to be speeding, just accelerating faster than the cop likes or chirp the tires.

It's a migration east, the folks here are tired of the way NV is going, the State is at the mercy of Vegas due to population growth. We now have Dem Governor and Senators, even Reno has become way too Lib, many people I know are heading to Idaho or Montana, but that'll open up some space here for a few more Californians who still think it's better than CA, but not for long as they are proving relocating isn't a cure for stupidity!

If you come to Reno, be aware we have smog requirements for newer than '67, no rolling 30 years, Carson city and south no requirement. I think we have the highest Highway Patrol officers per capita and they sure like to cite anything that even remotely looks like it goes fast!

I only have experience in Laguna with the local police. The city created their own noise ordinances, which are referenced on signs posted downtown and along PCH. I agree with your view George; CHP is typically the one who would check noise levels, tread depth, smog equipment, etc...  more rare to get that treatment from city cops and (in my life experience) unheard of for a Sheriff to worry about those sorts of items (unless you were a real jerk during the traffic stop)

I just watched some Fargo last night & that’s even looking more attractive. If I happen to get pulled over for excessive or unusual exhaust noise I think then it’s really time to let go of my 3 Panteras in the best winner take all package deal because I just can’t deal with harassment too well. But until then, will cruise with the rest.

Thanks for not ignoring me Ryan.

Local ordinances are something completely separate from the state vehicle code.

Is noise enforcement more of an issue in the cities of coastal Orange County or Statewide? Is it local police or the CHP that are performing the enforcement? If its only local police then complaints about the state of California are misplaced.

Jan in answer to your question, I don't perceive any noise enforcement taking place in Ventura. Every weekend Main Street in downtown Ventura is a constant parade of very loud cars and motorcycles … its been that way for a very long time. Nothing has changed … law enforcement is nowhere to be seen.
