Exhaust fines at checkpoints

**Steam** · 16th November 2006, 19:28

How much is the fine when you get stopped at a checkpoint for having a too-loud exhaust?
I will have the old exhaust in the shed for Wof time.

In a couple of weeks my exhaust will be just straight pipes, unbaffled, for fun and parties.

can bikes get stung for that? i didnt think it was technically illegal yet? i know the states have something like that, limiting the decibels, but didnt know we had it too? cos some harleys are amazingly loud...theres one in town that i can hear pulling away from the lights which are about a 5 min ride away, lol.

Yep, there are heaps of rules, and a home-made straight pipe probably breaks them all. I'm on a GN250, so it's not too loud even without an exhaust, some dude measured 95 dB without pipes, but you need to have an approved exhaust , and it can't be louder than the factory exhaust, which straight pipes obviously are.

Land Transport (Offences and Penalties) Regulations 1999
[Schedule 1 Offence provisions and penalties

7.4.1, Operates vehicle that creates excessive noise $250 fine

I think there is also an offence of tampering with an exhaust ystem, and maybe operating a vehicel in an unwarrantable condition. But I imagine excessive noise is what they'd do you for.

More likely, a pink sticker. Can't use the vehicle until you get a new WoF. (Pink? or green ? Can't remember)

But I've never heard of a roadside checkpoint just for exhausts. Only danger would be a general purpose drink drive check point and some Plod takes objection to the noise you're making.

"Ixion is moderately red (slightly redder than 50000 Quaoar) and has a higher albedo (0.15) than the mid-sized red cubewanos."

He is also a fount of wisdom, thanks Ixion, exactly the info I wanted.

ginnys are among the quietest around! most 50cc scoots are louder than a ginny [well, the indicators] my buddy knocked the baffles out of his, and another friend has a backed bean can as part of his exhaust! lol.

You get done for excessive noise, or a modified exhaust.

As above it carries $250 (recently raised from $150), and 10 demerit points.

You might also be given a GREEN sticker.

That it?!?!?! Jeeeez, I know of stock systems that come in around 102dB.

Mine is estimated at 115, then you go all the way to a Racefit slashcut, and you're talking 130+

Don't make a massive idiot of yourself, or become a target (ie riding around at top revs) and I find thats worked for me, never had my muzzy questioned.

I think this legislation is aimed at the young hoons on 4 wheels that fit a steel distbin to the back of their car - makes a load of noise which was really funny when I used to burn them from the lights with stock pipes on my FTO!

It didn't seem to add many ponies but these fellas seemed to enjoy the fact that their cars sounded badly tuned. People accept motorcycles are quite load but so long as we don't hang around traffic lights revving up and annoying locals I suspect we will all be left alone.

**Fatjim** · 16th November 2006, 22:35

what the legislation aims at, and what the coppers aim at are not neccersarily (sp) the same thing.

**slimjim** · 17th November 2006, 08:00

thought it was 109db, was the legal limit, and on a friend's Gz250 the tag rates the exhaust at 94bd , which is a surpise as its only a 250, but i don't know if the police will ask the reading to be read at 4000rpm,in neatural, fuck cause it gona be loud, my bitch if that is the case why then have gear's, as by using the gear's you control the noise ,and doing say 70mph you are still low on db's in top gear,while having loud pipes while using lower rpm,

**lb99** · 20th November 2006, 08:27

something along the lines of ".....not noticably louder than standard......" at the moment, I'd like to see a 1980s honda 4 with a standard exhaust still on it, so what are they going to compare to?, have the db limits been introduced yet?, cause how are they going to measure them in a standard fashon?

"erm yes officer, It did have an open cycleworks exhaust from the factory"

No you don't. No provision in NZ for exhaust approval. You must have an EFFICIENT silencer . Doesn't have to be approved by anyone. You can make your own, completely legal.

4. An exhaust system must be effective and in good
working order.
5. Noise from an exhaust system must not be
noticeably and significantly louder than it would
have been when the vehicle was manufactured
with its original exhaust system.

Reason for rejection is that the vehicle does not have an exhaust system with a means of sound reduction.

I had an 1986 RX-7, 1300cc rotary with an after market turbo and a 3 inch exhaust RIGHT THROUGH to the 5inch muffler with a 3 inch tip.

At the testing station it was at 132db. This was between 2002-2004, I never got done for having an exhaust to loud. HOWEVER I did get pulled over 20 times inside of the first 3 weeks I owned the car (which averages just under once a day :P
