Aftermarket Exhaust and New Rules

**Dave** · 28th May 2003, 14:53

This is such a load of shit-Sorry guys i haven't read the entire thing but are they doing the so called 'tests' at idle or on a rolling road at 100k/hr at full throttle? Huge difference.-don't know a testing station with a proper dyno-only brake testors.

bike still, 3,000 rpm and 4,000rpm tests, cant exceed 81db, isnt that right?

OK. Here's my submission, finally completed.

It's only taken 6 nightshifts to do.

**Dave** · 29th May 2003, 09:26

Very well researched and well done-I hope it doesn't land on deaf ears.(excuse the pun)

Just a little off topiuc, but do you guys reckon I could get another exhaust put on my FXR150? I would like to make it sound better and give just a little more kick.

Anyone reckon it's possible?

**Kwaka-Kid** · 29th May 2003, 16:21

hmm, i say go for it, or just take the muffler off - its a 150, how nouisy ca nit be ?:P secondly, i have one question mate.. if u were gunna buy such a small bike, i take it for learner licence? why not go for a RG150? i mean, i never thought much of those FXR's, 150cc 4 stroke? why not go 2 stroke scince ur limited to cc rating and then u get some power.. well limited but still? what made you do it ?

**Antallica** · 30th May 2003, 09:47

I didn't actually realise at the time that the RGV's were better... I would have got one if I could find one at the same price I got my FXR at ($2.3K @ 4,000km, mint cond.) But besides, all the RGV's I've seen have been such ugly mothers.

nice one slim!

Hopefully my submission (when it gets done) will be able to fill in some of the techy blanks you've got

I've got a busy weekend ahead of me I think!

Trying to dredge through all the technical info (or lack therof!!!) and make sense of the principles of the mess is taking ages.

Is it a condition of WOF Inspector certification to pass a hearing test (which employ measurable test methods and noise/frequency levels) and are they then required to have annual hearing tests to assure they remain qualified to conduct noise tests on vehicles?

ROFTLMAO

**Kwaka-Kid** · 30th May 2003, 16:03

nah it cant do, becase most officers couldnt hear those high pitched 2 stroke noises... deaf on that tone thanks to all the ear bashings of wife :P

mahahaha!

Hey motu, have they booked you in for calibration yet?

On NZ's self professed "NZ news leader" website www.nzherald.co.nz I could not find the article at all. But I am no techno geek.

Lots can be found on the Herald site about how NZ's Police is doing a lot to cleanup those NASTY boy racer types!

No limits to car noise

Jun 01, 2003

The Land
Transport Safety Authority wants new laws by the end of the year

defining how much noise a car is allowed to make.

A 20-year-old
man has had a charge of operating a noisy vehicle thrown out by the
Nelson District Court, which said the car had a warrant of fitness,

so is allowed on the road.

The LTSA says
the authority is consulting right now as part of the vehicle

equipment rule.

Andy Knackstedt
from the LTSA says the current law is not clear.

Motoring
industry groups are involved in the consultation process.

Everyone thinks a WOF lasts for 6 months,like the car or bike is in safe condition for a 6 mth period - WRONG! The only thing saving us from law suits and manslaughter charges is that the wof is for THE DAY OF ISSUE ONLY!!!!! In a wof test we are checking the wear and condition between THE LAST WOF AND THIS WOF! Tomorrow it could be 1000km away,or locked in a garage for the next 6mths. Just because it has a WOF DOESN'T mean it's leagal and safe.

That guy should of be fined - just because it has a wof is no excuse. See,it keeps coming back at the wof inspector!

Motu, it's a shame I can't find the more detailed article I read. It was actually thrown out because there was no standard test or test equipment that the owner could use to prove that his exhaust was compliant. In the absence of this it was accepted that the WOF was effectively the test (even though there is no direct test for exhaust sound in the WOF). What worried me is that the police said according to the rules it was uncumbent on the driver to prove that his exhaust was compliant, and not on them to prove that the exhaust did not comply.

If that's the case, the police can say anyone's exhaust doesn't comply, and it is up to them (at their own cost) to prove otherwise. It seems to go against the innocent till proven guilty stance that common law is based upon. Luckily one court has thrown a case out becuase there is no standard test or equipment that drivers can use......ie they have no way of defending themselves or disproving the charge.
