Big Bore Exhausts

[Trev]

Now is it my imagination, or were non-factory fitted big bore exhausts made
illegal some time ago? That is, they fail WOF.

If so, why the hell does about every 50th car on Auckland Rds have one of
these good-for-nothing-penile-envy-noisy-bastard things on them?

Damn sick of hearing them, plus they are on every nerd-boy-racer car you
see.

*SNIP*

It's your imagination.
The law bans exhausts that are louder than some particular limit (I
forget what it is) as measured in some particular way (again, I forget
the details). It wasn't an outright ban, just an attempt to deal to the
obscenely noisy ones.
And, IMO, it's failing miserably!

It is not even that specific - the WOF regs summary at
http://www.ltsa.govt.nz/media/2003/030619.html
: The legal requirements for exhaust systems and silencers are outlined in the Traffic Regulations 1976. The law states that "every vehicle must have an exhaust system and silencer which is effective and in good working order."

:Warrant of Fitness (WoF) guidelines have stated for several years that noise from a modified exhaust system should not be significantly higher than that from a standard system for the vehicle. To help WoF inspectors apply the law consistently and in line with roadside assessments by police, they have been given guidelines which clarify that a modified exhaust system which is "effective and in good working order" should not make a vehicle "noticeably and significantly louder" than it would have been when it was fitted with its original exhaust system.

There is no noise meter test, and conducting noise tests is full of
pitfalls, with ambient and reflected noise, weather, etc. A good
example is the noise restrictions at manfield racetrack (95db). A
vehicle can pass when the weather is fine, but low cloud cases
reflections...
I used to ride a bike that would have failed if I had raced it. never
had a problem with a WOF, but you coudl hear it 2km away on a quiet
day. can you say "cop magnet"?

Well..... I run a big bore... not excessively loud... but it would be
screaming down a residential street at 1am in the morning.

But how do I pass a warrant?... Id have to say it isn't even checked. Yup...
there is an exhaust, no leaks, no bad choking smoke... PASS

Hey there is even externally vented wastegates passing WOF's... and that's
illegal too!

There will need to be a crack down on the enforcement of WOF certified
places first. Honestly, there are heaps of backyard mechanics that pass
dodgy WOFs. Its who you know.

However ill stick to my 'non-grandma' Evo 6, that is fully owned by myself.
And yes, Im yes im computer nerd, a IT Manager/Programmer with Electronic

I can think of.

Aren't there noise limits which have to be met?

Friends running cafe racers in the early 1980s used to routinely fail
WOF on excess noise...

[Matt]

Not all WOF places hold the gear to do all the proper testing; ie audio
measuring equipment.



Really there should be two types of WOF's, one for un-modified factory cars,
and one a modified WOF - designed with more compressive tests for these
types of vehicles. Ie, noise emission, gas emission etc etc.



Been to a garage lately for a WOF? Seen them stick a sensor in your exhaust
with a lappy to measure gas emissions? - Not at my garage. Likewise with
noise emissions.



The other thing - my car is very quiet at idle and driven slowly so you
wouldn't notice the noise anyway.

Basically no WOF testing sites have a noise meter - it's not required in the
WOF legislation. The only guide is "not significantly louder than
standard." And there starts the can of worms. Pretty much every car I have
turned down for a WOF on the grounds of a noisy exhaust has instantly turned
into an "abuse the fsck out of the vehicle inspector" session. They then go
elsewhere for their WOF, badmouth you all over town and the only net outcome
is a reduction in your business. Any wonder that most WOF inspectors take a
pretty relaxed attitude to the more contentious inspection items?

Just one WOF will do, with much better policing of the issuing authorities
(and a huge reduction in the number of places that can issue them). The WOF
inspection guide states that you need 2 people to do a WOF yet a one man
band can have a WOF authority. You can't check steering properly without a
pit or 4 post hoist yet you can have a WOF authority even if you have
neither. The WOF legislation lays down requirements for the premises in
terms of access and facilities yet many (maybe even most) WOF issuing
workshops don't meet the requirements. Any wonder that most WOF inspectors
feel that the rulebook is flexible and can be applied however they feel (or
even ignored)?

Likewise with noise emissions.

There's no emission testing requirement as yet (although as usual it's being
talked about) but we should see one in a couple of years. The official
excuse for the delay is cost - making every WOF outlet buy $10000+ of
emission equipment would make many of them give up issuing WOFs (which would
be a real PITA in rural areas).
I think that the real excuse is a complete lack of balls on the part of the
policy makers. They are scared of the cost of a WOF inspection (or
complying with it's emission requirements) going through the roof meaning
that people just won't bother getting one. They are also scared of being
unable to police emission standards afterwards - given the total lack of
respect for noise requirements (easy to hear non-compliance) how are they
going to cope with an invisible item that can very easilt be ignored at
inspection time?
The best solution I can see for emissions compliance is to levy a pollution
tax on non-complying vehicles during a phase in period of a couple of years
but still let them have a WOF. Set the pollution tax at about twice the
cost of registration and then there's a financial incentive to fix the
vehicle.

Which is why all the WOF type tests are useless. Noise testing should be
done under load at moderate to high throttle openings - impractical at WOF
test time.

Yes well said. Personally (within reason), id prefer to see WOF's take a
more serious approach to vehicle saftey. I mean really thats what a WOF is
for, making sure the vehicle is safe to drive on the road. Most drivers with
big bores, better intake systems, uprated boost (if turbo), etc etc are
wanting to get more out of their car. However suspension and braking systems
should also be looked at if the vehicle say has 20% more power than
standard. (I dont know if something like this takes place - but I know there
are cars with 50% more power with standard brakes getting WOF's)

Yes emmisions need to be controlled, but to what limit? By someone's ear?
and sight? So the first WOF might turn you away, but the second one lets you
pass with flying colours?
I like the idea of a tax levy, its just deciding how to put a vehicle in the
compliant or non-compliant basket.

Very true, alot of the WOF testing stations locally here are inside
residential areas. Im sure they wont be happy with constant noise testing of
vehicles right next door 8x5days a week.

What's the problem with that? They're still only allowd to do 100 km/h.

The thing that really amuses me is that my non-turbo, stock exhaust
system vehicles (both the motorcycle and the station wagon) are very
very seldom matched away from the lights by the noisy vehicles. In fact
I'd say that in general the louder they are the slower they are.

I have no idea about Trev, but in my case I find that if I simply press
the accelerator in my car about 1/2 way then by the time I'm at 100 km/h
I'm usually at least 100m ahead of everyone else (this at traffic lights
on the so-called "motorway").

That's in a 4 cylinder non-turbo, stock everything, automatic, AWD
station wagon that weighs 1500 kg (about the same as a Commodore) and
gets 28 mpg around town, 32 mpg on the open road.

It's not a question of trying hard to beat everyone else. It's just
driving quietly and economically with the automatic changing up at
around 4000 RPM (redline is 6500). In fact I'm baffled why everyone
else is so darned slow.

I wouldn't say that that is an immutable Law of Nature, but
you've only got one source of energy and if you put some of it
into moving the surrounding air it isn't going to be put into
moving the car, which is the point of tuning the exhaust system
ie to obtain maximum transfer of energy, whether it be to wheels
or antenna.

Pretty much every car I
have turned down for a WOF on the grounds of a noisy exhaust has
instantly turned into an "abuse the fsck out of the vehicle inspector"
session. They then go elsewhere for their WOF

If the WOF system was being operated properly the fail would be recorded
in the national database and they wouldn't be _allowed_ to obtain one
elsewhere.

There should be absolute dBa limits on noise too.

An ordinary garage issuing WOF's has to log onto the WOF online system to
check the previous inspection status of a vehicle. All the info they get is
which of about 10 broad categories the vehicle failed under (eg
steering/suspension, tyres, lights, glazing/wipers, seatbelts, other, etc,
etc) - getting this info takes 5 minutes or so and pretty much makes the WOF
inspection into a money loser. And when they fail a vehicle these same 10
categories are all they can record for a failure reason.
A Transport Service Delivery Agent (testing station) that also does rego's
etc has full access to the LATIS database and can enter more detail as to
the failure (about 100 odd items) and add notes to the entry (and view these
too). The ordinary garage can't see these items or notes so has a very
difficult job determining what a previous failure may have been for.

I believe the Police have an absolute guideline and noise meters but there
are issues about traing and measurement methods being raised in court that
effectively prevent them doing much in the way of actual measurements.

Maurice Jobe strikes again....

If the vehicle failed the failure should be LOCKED IN so that it _must_ go
back to the same WOF inspector or be released by that inspector.

Measuring on the street is going to give all sorts of variations, but most
of those can be circumvented by measuring up close, at cost of more time
taken.

The other problem is that the same noise level gives differing annoyance
values depending on pitch and duration, etc. A quiet gas turbine is far
more annoying than a mildly noisy V8

Because a lot of V8 owners like 'em.

Of course, the younger crowed aren't allow them, because having a noisy car
is only okay when you're above 30.

Now is it my imagination, or were non-factory fitted big bore exhausts made
illegal some time ago? That is, they fail WOF.
If so, why the hell does about every 50th car on Auckland Rds have one of
these good-for-nothing-penile-envy-noisy-bastard things on them?
Damn sick of hearing them, plus they are on every nerd-boy-racer car you
see.

Well, then they are obviously not illegal.

I was asking a question.
