Question- I have an H pipe and active exhaust. Quiet mode is still very quiet (too quiet). Normal is WAY over the max. Is there any way to adjust the modes to normal is a bit quieter?

I definitely agree with you. I do tend to get on the loud pedal (pun intended) on certain 45-55 mph roads, but I don't pull holeshots, burnouts, or go over the speed limit (Seriously). I also short shift in neighborhoods, by schools and so forth. It's the problem children that cause bills like this to happen....I have a lot of respect for my neighbors so I putt through my neighborhood, between traffic lights and when in an area where my exhaust will echo...Bottomline, don't drive like a turd and you most likely have nothing to worry about.
I drove to Louisiana and back over the New Year. Admittedly I was in a Ford Fusion rather than the Stang.Here in Louisiana he would do fine. I'm running Corsa Extremes and my son is LTH/Catless/Corsa Extremes.
Makes no sense. Motorbikes round here are always soooo loud. They're always setting car alarms off on my street.I thought this law was designed for the mega loud harleys but seems to exclude motorcycles ?!?!?
i'd like to know the answer to this. does AB-1824 really affect Ford OEM exhaust? or are gt350's and gt350R's exempt? the bill says it applies to vehicles and motorcycles with “modified or excessively loud exhaust or muffler systems.” so for example, my R is not "modified" but might fall under the "or excessively loud" part. but really, fining a shelby for OEM noise? i wonder if the normal exhaust mode is under 95 decibels?So gt350 owners will always get a ticket with factory exhaust.
I don't think ANY factory exhaust is exempt. Car and Driver interviewed the guy at Ford responsible for sound levels. They asked specifically how Ford gets away with how loud the 2018-19 Mustangs are. His answer was that there are NO national standards just many many many changeable local standards, including individual city ones. So manufacturers CAN make an exhaust as loud as they feel like but try to have the quietest setting (for adjustable) sort of comply with the majority they are aware of. LoL So there could be some real interesting court cases coming up.i'd like to know the answer to this. does AB-1824 really affect Ford OEM exhaust? or are gt350's and gt350R's exempt? the bill says it applies to vehicles and motorcycles with “modified or excessively loud exhaust or muffler systems.”
I added the obvious emphasis above. So it would seem that J1169 is in effect, and that I was wrong in thinking it was idle speed, and is actually 3/4 max engine speed.Regarding the testing method, you are correct, J1169 is indeed a legacy test and the updated SAE standard is J1492. That said, California law is very specific about which standard is being used—Society of Automotive Engineers (SAE) test procedure J1169 (May 1998).
J1492 utilizes a “sweep test,” which permits continuous evaluation of exhaust system sound over a range of engine speeds. J1169 only measures single rate of ¾ engine speed, which some modern cars are unable to achieve when stationery due to engine management and/or fuel cut-off systems.
We are aware of this update and have amended our model legislation (on which California’s law was/is based) to reflect the change. We will be working with our allies in California, and the other states that utilize objective methods for measuring exhaust noise, to update the statute. We will also be working to rectify the fix-it ticket law.
As for the ticket prices, what is sited is the state’s recommendation. Ultimately it is up the local law enforcement agencies. Which city/county are you in? Their fine schedule should be publicly available. For instance, Los Angeles county follows the state’s suggestion for the fines.
I agree with you completely, but at the same time almost all of the larger aftermarket exhaust companies are located here. So shooting your tax base (Whether it be our sales tax buying the exhaust, or the company's taxable profits) in the foot seems foolish. Of course I say that drinking my water in a cup that doesn't have a straw that didn't come in a free "non-reusable" plastic bag...There is no interest in the state supporting aftermarket exhausts.
And as per usual a few people who have to be stupid loud make it difficult for the rest of us...
