Yesterday I got pulled up in my skyline (as you do) he asks me why I think I've been pulled up, I told him I didn't know (which I didn't), he proceeds to tell me it is because my exhaust is to load. So I say 'OK then are you going to test it then' He says 'I don't need to test it, your exhaust is clearly not a factory one and therefore must be certified.' I say 'I bought it like this, I'll just pop the bonnet and check if it is certed' Him: 'It won't be under the bonnet the cert tag goes on top the exhaust' I chuckle slightly and say 'I've never seen an exhaust with a cert plate in my life are you sure' He says 'yes, I'm going to let you off this time but you need to get it sorted, have a nice day' So my question is do you need to cert a non-factory exhaust! Just thought I would add that my exhaust isn't too load as in it is well under a 100dB.

No you wont, unless its over 92 decibels i think.

Yes the cop is right. I have not failed a wof yet on the new rules but if i do it has to go to a certifier for decible readings etc and they then put a tag on the tail pipe saying its ok. Not under the bonnet.

^^ yea as above - you lucky you got a warning. the wof test is a subjective noise test, this means if the wof guy thinks it's too loud (above 92dB) then you got to quieten it down (to at least below 92dB) or get it tested. the max noise level with noise cert is 96dB

yup, the cop is right about the exhaust cert.

Depends on the age of the Skyline in question.

That's right and if the cop had his hat on then he can't do nothing Also what sort of load are you carrying on your exhaust.

OK then I'm going to sell it soon anyway it's a 1990 gtst with an 2.5" HKS exhaust straight though, not load just a nice rumble. He didn't even test it. So if the exhaust isn't factory itneeds a cert regardless of the decibel rating! Is that going to cost $400 odd just to cert the exhaust!

Check sectionin the VIRM - covers both the different levels for different aged vehicles, and also the tail pipe labels mentioned above.

It only need a cert if a cop pulls you up and tickets you, or you can't get a WOF.
Mid engined cars also get another 4db on top of the 95 db allowable ^_^

and just how do you know its under 100db! I would go to the testing station and just get it tested for free, then if its under no need to quiet it down, if its over do something aboult it before you get a pink sticker then you will have to get it certed and pay $100 for a new wof

lol that sounds so arse about face.How is someone supposed to quieten it down to at least below 92dB if it doesn't get tested in the first (or second) place!

they will only fail a wof if its stupidly loud,had a bigbore on my libero for 5 years and never been failed or even talked about- because its not REALLY loud to be noticed at wof time. if an exhaust fails a wof for being over 96 decibels,it must be certed as under 92,if they dont fail you but say its too loud you can replace with a quieter one without cert. they basically told me if it is failed it must be quietened and be under 92

Where is this 92db level from!
(f) in the case of an MA, MB, MC, MD1, MD2, or NA-class production vehicle that was manufactured on or after 1 January 1985: (i) if first registered in New Zealand before 1 June 2008, 95 dBA; or (ii) if first registered in New Zealand on or after 1 June 2008, 90 dBA.

do more searching mate (i can't be bothered finding at the mo; but that was correct law as at nov '10). it's somewhere there around abouts 'subjective noise' search
also yes i think you are right about 95dB and 96dB - i got confused with aus

Jan 3, 9:05pm
oh lolololololol - yeah real funny mate!
my car went to vtnz - was too loud - went to exhaust cert place to test, 103dB - put more mufflers on (has 4 now) until reached 90dB - went back to vtnz - they said yip ok that sounds better - they kept a copy of the noise test from exhaust shop showing 90dB highest reading to cover their ass.

Okay speaking from experiance i got green stickered for a exhaust that was too loud i then needed to get a exhaust cert to get the green sticker off. I did that by taking it to my local certifier, he then certs just the exhaust system itself for 95 db costing 165 incl easy i then got a new wof through vinz /vtnz
