Title: new exhaust law $1,000 fine, not fixable
Post by: breakdirt916 on 01/10/19 07:01AM
any loopholes?  :32:

looks like I'll be happily switching commuter duty to the Ninja with a factory exhaust rather than the car alarm sounding Busa with the Yosh

Oh no, the misinformation campaign spread to you too?

Let me clarify the law for the 1000th time, because if you listen to Facebook if you look at your exhaust wrong they fine you.

1) The actual laws have not changed as to what defines 'modified to be excessively loud.'

2) If your (car's) exhaust is under 95dbA, has a muffler, and no cut-out device installed.. you're good. Even if they try to ticket you it's beating it in court like a speeding ticket. They don't carry calibrated db meters with them.

3) Doesn't apply to motorcycles. We have our own db limits defined and this law change specifically has text that excludes motorcycles. Here are the CA db limits for exhausts. Oh and any bike 2014+ must have a carb approval on their exhaust no matter the dbA rating.

A noise limit of 88 decibels applies to motorcycles manufactured after 1969 and before 1973; 86 decibels applies to motorcycles manufactured after 1972 and before 1975; 83 decibels applies to motorcycles manufactured after 1974 and before 1986; 80 decibels applies to motorcycles manufactured after 1985.

4) How is the testing applied? db meter 19 1/2 inches from your exhaust pipe tip (same level) held at a 45 degree angle. Engine rpms held steady @ 75%.

Edit: I think $1000 is a bit steep, but it has all those strait pipe idiots thinking twice from what I can tell on Facebook, so maybe not so bad. The biggest issue I have is with people trying to spread petitions that don't get the basics of the new law factually correct, and essentially try to scare people into signing them. If they presented them without the false information it would go a long way to increase credibility.

Item 3 in the above post states “ excludes motorcycles”, but then states “noise limits for motorcycles of various year ranges”, confused...

The $1000 insta-fine, as I understand, does not apply to motorcycles. I was just noting the existing db limits that net you a fix-it ticket currently (unchanged)

Thanks! This is one of the most informative posts I've seen in a long time

much thanks!

it's been so inconsistent and the memes surrounding "you can change your gender but not your muffler" are unfounded. looks like loud cars are getting popped and loud bikes will still get ticketed, just not the $1,000 instafine

80db on a motorcycle seems a little low though...

the facebook misinformation is a struggle...people keep posting the wrong info LOL

where did you read about the 19-1/2" at a 45 degree angle being specific to bikes?

https://leginfo.legislature.ca.gov/faces/codes_displayText.xhtml?lawCode=VEH&division=12.&title=&part=&chapter=5.&article=2.5.

^^ says regarding sale of new vehicles, it's measured..."which produces a maximum noise exceeding the applicable noise limit at a distance of 50 feet from the centerline of travel"

bobs muffler shows this from CCR1036 - but does this apply to motorcycles?

(b) Microphone Location. The microphone for the sound level meter shall be at the same height as the center of the exhaust outlet. The microphone shall be no closer to the pavement than 8 in. (203mm) when the exhaust outlet is lower than this height. The microphone shall be positioned with its longitudinal axis parallel to the ground, 20 inches plus or minus 1 inch (508mm plus or minus 24mm) from the nearest edge of the exhaust outlet, and 45 degrees plus or minus 10 degrees from the axis of the outlet. For exhaust outlets located under the vehicle body, the microphone shall be located at the specified angle and at least 8 in., (203mm) from the nearest part of the vehicle. For exhaust outlets that make an angle of 45 degree or less with the longitudinal axis of the vehicle, the microphone shall be outboard of the exhaust axis. For exhaust outlet angles of more than 45 degrees, the microphone shall be on the side of the exhaust axis to the rear of the vehicle.

"(c) Test procedures for compliance with this article shall be established by the Department of the California Highway Patrol, taking into consideration the test procedures of the Society of Automotive Engineers."

Pretty sure CCR1036 will apply as it is SAE standard. That seems to be the CHPs most current testing procedure.

Does anyone know why this law was passed in the first place?  That has me puzzled...

Two very simple reasons.

1) Existing fine/fix-it ticket was clearly an ineffective deterrent. Loud pipes in car culture has been getting increasingly worse the last few years as far as d-bags with open pipes in their 2018 Camaros/Mustangs/etc. Yes "ricers" always had their fart cans and muscle guys had loud exhausts but these new Corsa pipes are ridiculous.

2) Income.

1. modify exhaust
2. get fix it ticket
3. go back to stock, get fix it ticket written off
4. repeat step 1
