Outer Limits 4x4 Board

From the MCCofNSW Noise Comittee

WARNING: DECC (EPA) are proposing NEW noise laws.

>>> For immediate and wide distribution <<<

The following link is the Regulatory Impact Statement (RIS) that DECC have issued to assist with the introduction of the proposed laws.

www.environment.nsw.gov.au/resources/07186noiseris.pdf

The following is my rough outline and by no means a complete overview of the proposed laws that DECC will be presenting to the government.

Clause. 18
"Noise control equipment to be properly maintained"
A person must not cause or permit a motor vehicle to be used on a road or road related area if:

The motor vehicle's noise control equipment allows the emission of more noise than the original noise control equipment fitted by the vehicle manufacturer, or

if an authorised officer (police etc) reasonably believes the equipment has been modified in a way that makes it less effective than it would have been if the modification had not been made, or

the motor vehicle's noise control equipment is not securely in place, or

a temporary noise reduction device is fitted to the vehicle (like a removable baffle, even if it is fitted and the vehicle is compliant to it's noise requirements) or

if the equipment allows gas to escape from a place other than the intended exhaust outlet.

And

A person must not:
Remove, or

render less effective, a motor vehicle's noise control equipment, otherwise than for the purpose of repairing or replacing it, or

replace a motor vehicle's noise control equipment with noise control equipment that is less effective than the original noise control equipment fitted by the vehicle manufacturer.
Fine: $200 *

* Penalty levels
The maximum penalties provided under the Noise Control Regulation for a "Court prosecution" are currently $16,500 for individuals and $33,000 for corporations.

DECC said of Clause 18; The aim of clause 18 is to provide a means of detecting noisy vehicles that avoids the cost and time associated with noise testing where it is not strictly needed. Noise testing is often not required to identify the fact that a motor vehicle's noise control equipment is defective, and a simple visual test and aural check is all that is needed. However, in cases where noise control equipment is modified and the officer is unsure whether the noise control equipment is less effective, a noise test should be carried out. Noise tests are often carried out by DECC authorised officers to support the finding of defective noise control equipment. In practice, a Police Officer's ability to carry out noise testing is limited by the cost of the equipment, lack of trained personnel, and competing priorities.

Use of informed subjective (guessing!) assessment to decide a noise offence is central to NSW noise legislation. The concept of offensive noise underpins the legislation. Powers under the POEO Act and existing Noise Control Regulation enable officers to exercise judgement in deciding whether noise is an issue.

DECC urges stakeholders to provide feedback on the new Regulation.

Being a motorcycle rider this is very important
" A Copy and paste from a motorcycle forum"
Mods fell free to move if needed .

well that sucks ass

From what Im understanding, that is saying that anything other then a standard exhaust is illegal.


Is it for every state?

When does it come into enforcement?



That just blows.

While parts of that make sense - the rest is Bullshyte ..... Do these wnkers lying in bed at night thinking up new BS ideas or what.....

Hey Midnight, read through it, it seems to infer NSW only, and it is being proposed, it hasn't passed yet.

I wrote a uni assignment last semester at uni; about driveline noise management in motor vehicles. It was just a research assignment, with no personal experimenting done etc, and was only short.

Anyway something I found out rather frequently was people getting worried about how quiet some modern cars are, its unsafe you cannot hear them coming! (particularly these hybrid POS). Anyway I got 9/10 for the assignment . It was for engineering acoustics BTW.

That being copied from a motorcycle forum, I can see a bunch of HD owners chucking a massive shirty, thats why you own a Harley, they sound so pleasant with a de-baffled exhaust.

Wonder if you'll be able to mod-plate an exhaust if those laws pass? What a PITA, dont they understand some aftermarket exhausts improve emissions; and make the engine more efficient. They're sleeping with oil company executives, thats it; the tools!

yer my understandin was only nsw..but hey if a crap rule it will come to qld

pleasant? what do they say about harleys? how to turn fuel into noise without the effects of horsepower

these laws that these tools come up with are absolute bullshit
think of all the exhaust companys that are going to loose business over this crap

I keep hearing this, but I have yet to see it proven.
Car companies spend billions designing their cars, if it were possible to get more power and better fuel economy from an exhaust while staying within the noise regs then they'd do it.

Exhaust flows at cruise are a fraction of full power, which is why putting a 3" exhaust on a 1.8L japanese 4 cylinder offers no fuel economy benefit at all.

Don't get me started on those muppets who put an echo chamber on the last 3 inches of their exhaust and claim it's a "performance exhaust".

Doesn't matter, they don't boost at (legal) cruising speed.

so how do they get to "cruising speed"??

j-top paj wrote:what do they say about harleys?

what do they do about them now? fukorl.. or ever?

this has been discussed for week or 2 on the bike forums, people are shittin, specially those that have second hand bikes that never came with std pipes - which on some bikes are $3500+ for complete OEM system..

I Cant really figure out who this is to combat ? Gino with his gal garbo can exhaust on his Civic?

j-top paj wrote:so how do they get to "cruising speed"??

The ones I see appear to be propelled by noise and black unburnt fuel.

I'd have a guess to say that the worst offenders are the bikes followed up by the ricers. I did hear that the Melbourne side of Gembrook was closed due to the noise generated by the bikes annoying the home owners.

This isn't really anything new by the way, there have always been noise restrictions on vehicles, most only JUST pass the noise test (i have a calibrated noise level meter) as factory standard.

u sure thats fuel?

I too heard this.. I was also told that when EPA did testing, the loudest noise for all the testing was from the main dude complaining's chainsaw...

Yep, the turkeys who put vented BOV's on cars with MAF sensors, the ECU still thinks that air is going through the engine and dumps in the appropriate amount of fuel. A big puff of black unburnt fuel comes out the back with each fart of the BOV.

Then you've got the ones that're running retardedly rich in the hope of gaining a little more power.

sounds like you dont like ricers very much

j-top paj wrote:sounds like you dont like ricers very much

Only the dumb annoying ones.
The type that lower their car by taking springs out.

so what your saying is there is no reason to replace the stock zorst on a car. no HP gains, no increase in fuel economy. and even with a turbo a waste of time?

you sir are an idiot.


On the other hand this law makes a mockery of legislation.
it states that even if the car is complient with the law but an officer "believes" it is louder than they are breaking the law. wtf is the point of haveing a testable noise level if its up to an individual's interpretation?

Nice of you to put words in my mouth, then call me an idiot because of then.
Since they're your words, I believe you just called yourself an idiot?

In the immortal words of Jeremy Clarkson, "Thats rubbish"

I doubt it will pass

Bring on these rules I say.

There is no reason an exhaust shop cannot fit an aftermarket exhaust which flows better and is still as effient if not more efficient at stopping the noise. Maybe the exhaust dude that had that big thread can comment on this.

The problem with current laws is that the wanker harley owners fit those stupidly loud exhaust, get defected, they just put thier old pipes on, clear the defect, then fit thier noise makers again.

$200 fine should be a bit of a deterent.

There was a farkwit that lived up the street with a harley always used to fire it up nearly every sunday morning at 7:30, let it idle for no shit 30 minutes, then go off on his cruise. Thanks for not letting me sleep in farkwit! $200 fine, bring it on.

Did you notice the noise regs thing he also wrote? or do you just skip the parts you dont like?

I happen to think that you can get aftermarket exhaust which can both increase performance, cut emissions, and still maintain the factory noise level, but they come at a very high premium. Most people just go the peroformance route, and couldnt give a fark about the pollution and noise. These laws will force them to consider the noise component.

that doesnt mean you cant obtain them, i never said you couldnt he simply stated the OE system is the best out there and that simply isnt so. if it was zorst shops would cease to exist.

the laws set a dangerous precendent.
imgaine if syspension laws were the same a cop thinks its to high or too low but is within the law. his oppinion would overide that and you would be fined.

until you proved it wasnt, or if you were smart, carried the documents proving it isnt with you.

ANd in my opinion he is wrong aswell, that doesnt make him an idiot. Im sure youve been wrong before havent you? So are you an idiot? A?

I'd like you to show me an aftermarket exhaust which improves performance, econonomy and emissions while staying within the noise regs.

I don't think you could. No matter how many times you want to misread what I write.
