I went for a WOF yesterday on the bike (hard to believe I have almost owned it for a year!). I went to the AA WOF station in Hornby, Christchurch.

There was a Harley sitting outside with Vance & Hines pipes - hmm I thought that will be loud - he fired it up and it was mellow - almost quiet. Weird.

Anyway the chap doing by WOF recognises me and we chat about bikes while he looks over mine. I ask whats the guts with after market mufflers under the new rules.

He told me that they have been told that if it is a modified stock or aftermarket pipe fail it. Irrespective of noise level. They will only pass it if it has been certified ($140 apparently).
I also learnt that if a cop stops you for loud pipes its 25 demerit points now :mad:
I told him I could order pipes that pass EU certification and are well under 100db (under 90 on some). He said they fail them for not being stock unless they have the certification sticker.

So if you are ordering slip-ons from your bike shop - ask them if they will pass them at WOF time as non bike shops probably will not. Or figure in a extra $140 on top of the purchase price.

What happened to the Harley???
It failed for two reasons - non stock pipes......and half a meter of wound-up chicken wire stuffed up each pipe :whistle::whistle::whistle:

well, i just passed a warrant, the first one i have had to go for, i have buell factory race pipes on the bike and the race computer, the fine gentlemen at the shop are well aware of this.
perhaps you can get away with it if its oem....????

Exactly - this is what I suspect will start to happen more - one local dealer in CHCH has a stand with tasty Leo Vince pipes on it - with a disclaimer stating fitment is at owners risk.

If you get on the old google and search any of the major European brands of cans they all come fitted with db killers (street pipes) that meet EU standards. These standards are a lot lower than NZ's new 100db (pretty sure they are about 88). I know the spunky MIVV pipes have the type approval stamped on the mufflers.

Unfortunately it looks like this is being ignored by WOF inspectors unless they have been independently NZ inspected.

Ironically it is likely that a EU approved muffler without its db killer insert will just pass our 100db maximum test.

That's government for you. :spanking:

yea and for all those people that bought a bike at a summer feast with an after marke pipe and didn't get the stock one, buying one new will hurt the bank ballance,
this is the third time i've hear this in chch since the start ove the month, its only going to get worse , and i here they are making people re fit Catalytic converter as well.

Have to agree with Scracha, just got a WoF for mine with yoshi's on it, from the local bike shop.

If some bike shops are selling aftermarket pipes for street legal bikes and then failing it for the WoF then surely they are breaching the Consumers Guarantees Act by selling a product that is not fit for its purpose.

That is very encouraging. I'm taking my wife's XB12S with race ECU & race muffler for a WOF tomorrow. I phoned the dealer we bought the bike from and spoke to their workshop people a few weeks ago to enquire about how they dealt with the exhaust noise with our setup. Seems they haven't had an XB12 with a race muffler needing a WOF yet, so they are looking forward to doing a sound check on ours....

Would that be an objective decibel reading from the cop or the usual "because i said so" response? A timely post as i had planned to get MIVV slip ons (keeping the CAT) or complete Staintune system replacing the lot for the genuine Ducati rasp. Feeling somewhat chastened here but where there is a will there HAS to be a way!

oh..AFAIK euro pipes are under 86Db. Perhaps we should lobby for bikes with a nice yurropean stamp to be automagically approved instead of pissing away more money on an enzed reinvention of the wheel?

I didn't get the WOF done on my wife's Buell yesterday - change of plan. Instead we just did an informal sound check to see if we needed to track down a standard muffler or not. Interestingly the sound check registered a reading of 99Db and the service dept were happy with that, so when I take it back on Thursday for its WOF and 16k service there won't be any drama regarding noise.

As always, bikes that aren't loud, will get warrants, regardless of who made the muffler.

The possible problem for you here is the 'informal' sound check - sure they will give you a WOF BUT if you are pulled over by the police for a 'documentation' check :Police: and the officer decides it is too loud you'll get a on-the-spot $50 fine and 25 demerit points. Irrespective of the new WOF as you may have modified the pipe to get a WOF.
Without a certification sticker on your bike proving it is 99 db the fine and points will stick.

Not necessarily.... as there is also a note somewhere in there regarding modified pipes - the document you have provided is only relating to the inspection for noise testing. As I stated the station I went to will fail any non stock pipe unless it has been certified.

I believe the bike shops will pass bikes for WOF's if they have aftermarket pipes as long as the db inserts are fitted. DITTO the police if pulled over.

I think this will end up like the braided brake line regs a few years ago - to start with they failed everything with braided lines. Then they issued a set of standards that were suitable for braided lines.
I believe mufflers will fall into the same category with EU and Aussie standards will be accepted (if stamped on the inside of the pipe). After all these standards are a lot stricter than our 100db max!!!!!!!!

Write to the minister of Transport - I intend too.

You are here: Home › Vehicle ownership › Noisy vehicle



Your vehicle failed a warrant of fitness because of a noisy exhaust
Why is checking the exhaust noise part of the WoF inspection?

When your vehicle was manufactured it was fitted with an effective exhaust system, including a silencer. Exhaust gases produce a significant amount of noise. Silencers, as well as any catalytic converters, muffle this noise to an acceptable level. Governments specify the maximum noise levels that vehicles must not exceed when they are manufactured.

When the original exhaust system is modified, replaced or repaired, its effectiveness may be compromised, making the exhaust system louder than the one originally fitted by the vehicle manufacturer. A WoF inspection ensures that the vehicle’s exhaust system is checked regularly for noise output and meets the legal noise requirements.

What are the legal noise requirements?

Until now, an exhaust system was allowed to be noisier than the original exhaust system, provided it was not significantly noisier. As a result of public complaints about the number of noisy modified vehicles on the road, and the difficulty in assessing what ‘significantly noisier’ means, the government has introduced more stringent requirements relating to exhaust noise effective from 1 June 2008.

A vehicle will comply with the new law if the noise from the exhaust system is similar to or less than the noise from the exhaust system that was originally fitted when the vehicle was manufactured.

The exhaust system may be noisier than the original one provided that:

the noise output either remains well below the legal noise limits, or
an Objective Noise Test proves that the exhaust system does not exceed the legal noise limits.
How is exhaust noise checked during the WoF inspection?

The WoF inspector uses his/her experience to assess the noise output of the vehicle compared to other identical or similar vehicles in original and good condition.

If your vehicle is noisier than it was originally, it will fail its WoF unless it is able to pass a Noise Quick Check. If the WoF inspector has a hand-held noise meter he/she will use the Noise Quick Check to find out if the vehicle is well below the noise limits.

If your vehicle has failed its WoF because of a noisy exhaust, it may be referred to undergo an Objective Noise Test.

What is the difference between the Objective Noise Test and the Noise Quick Check?

The Objective Noise Test is a stationary tail-pipe noise test procedure based on international standards and can only be carried out by an approved low volume vehicle (LVV) certifier. If your vehicle passes the Objective Noise Test the LVV certifier will attach a label to the vehicle and issue a certificate. The cost of the test is about $130–200, depending on location. It is a one-off cost provided the exhaust system is maintained in good condition and is not modified further.

The Noise Quick Check procedure is a simpler and quicker version of the Objective Noise Test, making it suitable for WoF. It is used to assess whether the vehicle is well below the noise limits or referral for an Objective Noise Test is required. The Noise Quick Check can only be carried out by a WoF inspector who has an appropriate noise meter. A fee may be charged for this check.

What do I need to do to pass the WoF?

Replace, remodify or repair the exhaust system so that the noise output is less than or similar to the noise output of the exhaust system that was originally fitted by the vehicle manufacturer, or
Undergo an Objective Noise Test if you wish to have an exhaust system that is noisier than the original exhaust. However, you may still need to replace, remodify or repair the exhaust system to bring it below the legal noise limits. An Objective Noise Test is not required if the vehicle can pass the Noise Quick Check.
Should my vehicle get an Objective Noise Test even though it has passed the Noise Quick Check?

If your vehicle’s exhaust is louder than its original exhaust system and close to the permitted noise limit, then it is recommended that you have an Objective Noise Test carried out. By presenting the label and certificate to the WoF inspector you may avoid the inconvenience and cost of failing a WoF or having to go through a Noise Quick Check at every WoF inspection.

What are the noise limits?

In order to pass an Objective Noise Test, the vehicle must not exceed the following noise limits.

Vehicle type Maximun
noise level
(dBA)
Motorcycle or trike with an engine capacity of 125 cc or less 96
Motorcycle or trike with an engine capacity of more than 125 cc 100
Light goods or passenger vehicle (eg, car, MPV, minibus, ute or van)
First registered in NZ before 1 June 2008
First registered in NZ on or after 1 June 2008, and:

manufactured before 1 January 1985
manufactured on or after 1 January 1985



95



95

90
What if I disagree with the decision?

If you disagree with the decision to fail your vehicle, you should first try to resolve the issue with the inspecting organisation or the LVV certifier concerned. If you are still not satisfied, you may raise a complaint with Land Transport NZ, phone 0800 699 000, or download a complaint form.

Where can I get more information?

A list of approved LVV certifiers can be viewed on the Low Volume Vehicle Technical Association website: www.lvvta.org.nz

So really the buggers should have a noise meter on site, other than 'using his/her experience'. After all they are offering a service to issue WOF's and should be expected to have the necessary equipment on hand instead of saying 'get it certified for $140 down road'.

Mind you that can get expensive - I cannot see bike shops buying the dear ones, but a cheap hand held one under $300 would be better than some old farts ear.

This would be a good investment .
Owning a hand held that you carried with you .
Mr plod says too loud ,you say read the fucking meter!
If it is a cetified meter, you got him fucked!
Cheaper in the long run than fines and demerits
I see you can buy them on ebay cheap too.

Please would a member of the constabulary correct me if I'm wrong.

If you are subjectively assessed as too loud at the side of the road then the ticket would read something like, 'prove you comply with the rules or else you win a $50 tax and 25 demerits'.

If you passed the objective noise test then you'd be out of pocket for the $120-$200 fee and inconvenienced to hell, BUT you'd avoid the ticket altogether???????

You'd also have the sticker/cert thingy to wave around the next time you get stopped or wofed.

But the noise measurement is 100 decibels for a motorcycle larger than 125cc and 96 decibels for a 125 and below FFS.

Most bikes - even with race exhausts - would struggle to hit 100 decibels. 100 is farken loud.

And coz my bike is an air cooled, 2 valve per cyclinder twin it gets measured at 3,000rpm....at which point my bike sounds quite tame. She sings between 6,000 and 9,000.

Same the VTR is water cooled mine 4 valve per cylinder and gets measured at 4000rpm like yours is pretty tame and the bark doesn't really happen till about 6500 and under a load...

But the guys at the shop said its not that loud, but I don't find it offensive...

100% correct - however they have that phrase regarding louder than stock. If they believe it is louder than stock and you have not got the certification sticker to prove it is within legal levels they can ticket. Its up to you to prove it is a legal pipe. Guilty unless you can prove otherwise. :wacko:

The whole measurement level is flawed as well IMO - why not just set all bikes at 50% of redline? Was that too easy for the committee and did not allow them to charge more?
In point:
My Hornet redlines at 9500 - noise test at 4500 that's 47% of my bikes max revs.
A GSXR thingy redlines at say 14,000 - test at 4500 that's only 32% of max revs.
Guess which engine is working harder and making more noise.

On the bright side, at least my Honda will last longer - he he he he

That is actually the recommendation,the chart is just a guideline for various motors.Without a tacho it's all a guess anyway.This is for the subjective test anyway,it's not official....it's called the ''quick test'',and that's all it is,a quick test.That's why the limits for the quick test are set lower than that for the objective test.

Just spoke to a local (to Palmy North) ONT certifier and he said that I was the first biker he'd heard from. Anecdotally, around here they're coming down really hard on boy racers but leaving bikers pretty much alone. Won't be long tho til they widen the net.

Pricewise he said the quick test (hand held) cost $40 and could be done while you wait. The Objective Noise Test costs $170 and takes 2-3 hours. You have to book it in well in advance because they have to order in the equipment to conduct the test. The cert sounds like a real PITA involving detailed drawings and descriptions of the emissions system.

Yeah, I have a guy that looks after us well (I doubt his test requires batteries). I'm still interested in knowing where I am on the scale. Would be handy to know in case I'm ever challenged at the roadside.

Getting your bike/pipes certified isn't gonna help one little bit if you're unlucky enough to get a picky cop or rub them the wrong way.

Latest legislation says noise levels have to be 'similar or quieter than stock' if you have aftermarkets or modified exhausts. It's mostly aimed at the big-bore boy racers that keep the Merivalians awake in CHCH, but bikes have been lumped in too.

Depends on whether you get stung for 'Noisy equipment' or 'Operating in a Noisy Manner' as to whether you get the demerits or a bigger fine.

As for warrants, stick with the places the Harley shops recommend.

Not quite correct - you may run a louder system - and if it is certified (yoou get a document to prove this) the police will not be able to ticket you.

LTSA says:
The exhaust system may be noisier than the original one provided that:
the noise output either remains well below the legal noise limits, or
an Objective Noise Test proves that the exhaust system does not exceed the legal noise limits.

He told me that they have been told that if it is a modified stock or aftermarket pipe fail it. Irrespective of noise level.

That has been their policy even before the new laws as I had the problem when I had a set of drags they wouldn't pass because they were aftermarket.

Solution - took the bike to a place that knows what it's on about rather than having a policy not reflective of the law.

You should check the CKMC website, March Hare video if you want to see Chucks rip roaring m109R with aftermarket pipes. Loudest friken bike at the rally, I'd place a wager!

I went for a WOF yesterday on the bike (hard to believe I have almost owned it for a year!). I went to the AA WOF station in Hornby, Christchurch.
That place has always been tough, its all a crock a shit there are older cars and bikes out there that you can not get factory exhaust systems for, any inspecter that fails a reasonble after market pipe is either a wanker or sceard of geting in the shit if his boss catches him or its involved in a acco up the road.

Got WOF (at the local testing station) for the firebolt last w/e with race can on it old boy didnt give a shit was more worried about the lack of a reflector.

The rules are aimed at little fuk boy racers and jocky knobs on Harleys with open pipes etc... blame them not the inspector.

Getting your bike/pipes certified isn't gonna help one little bit if you're unlucky enough to get a picky cop or rub them the wrong way.Not true... if your pipe has, riveted on, the LVVC plate that is given to you when you pass the objective test, then nobody can do or say squat. That's the whole point of having those plates... no disputes.

how can they tell if its aftermarket or not? mine looks just like stock.

They are X-spurts, these guys : they know everything.

Or, they could just look at the can - most cans (Japper, at least) are marked (by international agreement, and for compliance purposes) with shit like the manufacturer, what standard they comply with, etc.
Aftermarket can manufacturers like to advertise their wares, so their cans are only marked with labels that don't correspond to bike manufacturers (or parts manufacturers) names.
Factory pipes often look ghey too: huge, non-styley, heavy, boring, quiet...

True, you can get a warrant with a certificate.... BUT since the boy-racer legislation came thru about a month or so ago, charges of 'Noisy equipment' and 'operating in a noisy manner' have been introduced.. it's a whole different story on the roadside.

The test for the snakes is that the machine has to be "similar or quieter than stock". Don't believe me?? go ask the cops, just don't do it on a noisy machine.

By the way, I have a VERY noisy bike.

'Similar or quieter than stock' does not apply to exhausts that have been certified and plated by a low volume vehicle certifier, it applies to exhausts that haven't been officially checked and plated as such.

I reckon my old XJ Special (with stock standard) pipes would have probably failed... however the back end blew out of them and the were a bit rusted... so I thought I would replace them...

Point is, I tried to get more pipes for it and could not find any nor could I get any imported they stopped making them a couple of years before and had non left in stock... so I ended up putting bike cobbies on, they sounded nice...

Now this bike with its cobbies would have passed 20 odd WOFs in the past with no problem... but now all of a sudden it would most likely fail... (lucky I no longer own it) and no way of getting stock pipes... so would be a trial and error to see if the aftermarket pipes were as quiet...

This is the same as the enquiries I have made - louder aftermarket or modified pipes are fine as long as they are within the legal limits and are certified.
When I get the bucks for pipes I'll allow the extra for certification.

The WOF guy did say certified pipes will pass.

What there is in Christchurch is a good opportunity for a bike shop to start doing Saturday morning WOF's

Correct.

Oh and yes my new bike fits your factory pipe description very well! But at least it's legal... my modified M109R certainly wasn't!

Another bonus of the kits Like the Hotbodies tails that tuck the pipe up under the centre of the rear fender. You can only really see the end and tip, so who can tell whats stock and whats not.:innocent:

I reckon my old XJ Special (with stock standard) pipes would have probably failed... Only if it was too loud... factory pipes, no, pass objective noise test, yes, no trouble... seems a little loud, cert required, doesn't pass, was too loud anyway, modify to suit, stamped and will pass forever. Forever is relative... but a bit of effort has gone into the current system, seems unlikely that it'll change in the foreseeable future.

The WOF guy did say certified pipes will pass.Yep, takes the onus off of him, so he's happy.

Interestingly enough, I took the Enfield to AA Hornby for a WOF last month and it was failed on a 'noisy exhaust.' $140 and an Objective Noise Assessment later and it passed. 93.7db was the reading, but what fucked me off severely was that it has a FACTORY PIPE AND MUFFLER. As a result, AA Hornby (and all other AA stations) now lose the income from mine and Mrs Serialunderachiever's six vehicles that we've previously had WOFd there in the past.

All I can say Is I am waiting :nono: My Jardin GP-1 puts out 110Db at 6000rpm and I seriously doubt that it would pass at 4500.

Where in Auckland does casual noise tests?

The whole system is fucked. If you put an aftermarket pipe on and have it certified a cop can still stop you and ask you to have it certified again - there is no "life-long" certification. If the cop asks you to prove it's not too noisy you have to pay for the certification, and if he stops you a week later he can ask you to prove it again, afterall you may have pulled out the baffles after the certification. And forget just leaving the stock muffler on - that's fine if your bike is recent but as they get older it becomes harder to find "stock" parts.
But what someone said earlier is true - if it sounds quiet they won't even ask even if is is stamped "noisy fucker exhausts ltd".

Well I for one am damn glad I came across this thread.Was about to list my factory pipes on Trade Me but thought I'd ask in here about a suitable price range,guess I'll be keepin em now,the ones I have on at the mo keep setting off car alarms,great fun for riding round mall carparks but doubt they'd pass the noise test.

mwahahaha this is all a crock of shite. some places do one thing. others another. in the end just have to find a good shop.

my wee nc21 has a nice big fat hole in the main exhaust which makes it noisy as but mr. WOF man no care. he wants reflectors and the rear brake lights reconnected. fair nuf i say

i think some shops are scarred (and acting like idiots) and some are using common sense. find a person with a brain and a reasonable exhaust will be no probs.

Another issue is how the noise testing is being done. It cannot be done just anywhere due to the amount of ambient or existing noise. Nor can it be done in a building or an enclosed courtyard, due to reflected noise. Nor can it be done on a windy day, raining day etc as all these factors will affect the outcome. Also a cloudy day will affect the noise level compared to a clear day. This is really just a big snafu, and the poor average bloke cops it.
There is only one true way for noise testing, and it is not being done here in NZ. I even witnessed a stock VL800 being tested and it failed, it was being tested INSIDE the building. The tester said it is above the limit, it fails, the stock pipes were pointed out, and the markings on them too, he replied "I don't care" the bike had only been PD'd by the dealer, and had only done 7km, no the pipes had not been modified either. This is truely scary. idiots are being given a piece of equipment and do not know how to use it appropriately. There is a lot more than meets the eye (ear) with noise testing.

I just used a handheld noise tester to do the DRZ.

its got a full yoshi system, with the insert removed. Its farking loud when at full noise.

However, a stationary test, stood behind the bike and to the side (about 3 meters away) and revd up to about 3-4k only produced a reading of 86db.

Was that the correct testing method?
At full noise I reckon would be about 110...

I had a LVVTA inspector bring his noise meter in to try out on my XT.
He just stood almost beside the bike,held the meter at about 45 degrees from the end of the muffler and about 30ish cms out from it.
Then he just said roll on the throttle to 3250 (which is what his book said to rev mine to) then roll off again and violia,noise tested.
Now mine wasn't an official test,just more of a wanting to know test.
It was also done inside our very large workshop,so the noise would have echoed quite a bit.I got 101.5db,which was 1.5db over the max limit.It has a two brothers muffler grafted on,which probably came from a big sports bike going by their website.We also gave it a big rev and it came out at 105db,very loud by any standards!

Yes,it was done inside.Take it outside and it would have been under 100db.I was only doing it for couriosity's sake and to give me an idea of what I am working with.

You could just buy some Two Brothers at WOF time we can lend you some low db noise inserts that will pass any test they fit in around 5-10mins very easy to fit
