What about my Harley?, its standed mufflers don't baffle shit, its over 110 dba with standed mufflers

That's OK.. If it's standard it's OK whatever loudness. Yeah, I dunno what they were on when they wrote the law either, but whatever is was they seem to be able to get plenty of it. Y' just have to be able to prove their OEM standard (and not doctored)

I am terribly sorry I am not really an aggressive person But when people call me out I am afraid I tend to chuck the pen away and keep going with the sword. But dog shit or scumbag or whatever he goes by hates me because he rides a Harley and really that's his misfortune not mine.

Oh well time for the Valium.

Whew!
'dogshit or scumbag or whatever he goes by hates me because he rides a Harley'
I was worried you were meaning ME - but then I remembered I don't hate you - and my name ain't 'dog-shit' or 'scumbag' - but I DO ride a Harley. (close-call eh?)

What about induction noise? I have a stock exhaust, but the induction noise is way to freeking loud.

Besides which mate, I may post some stuff that may be controversial, [/I]

I know my user name pisses you of. But don't blame me for buying a Harley. But if your gunna poke shit, you've got to b able to take it as well.

Controversial posting now that would be an absolute understatement regarding the sick stunt that you pulled of back in August with the sick posting of cats wrapped in glad wrap for sale at the Mad butchers. Dude you are one sick puppy. Maybe I should forward it to Peter. How would you like him to sue the pants of you for using his franchise name in a derogatory manner? Anyway on yer Harley sunshine and piss of. It is you that is the deranged, and angry, try some Prozac.

Now getting back on topic Why sell aftermarket pipes if they are going to be deemed illegal, well in NZ anyway.

Sorry to say but this is wrong....OEM pipes and exhaust dont make your bike legal under the new law....it states that, factory vehicles with factory fitted exhaust systems will still be subject to the new decibal levels and made compliant to the new levels. If the harley is over the 100 decibals with a OEM pipes you will be failed. even some new vehicles being brand new will not be legal under the new law str8 from the factory and will have to be modified to comply before they can be sold here....I know this Sux but what can you do??

so remember the decibal levels are as set REGARDLESS of factory systems or not.

I think you may be confusing the rules about entry certification and those about in service testing (ie WoF).

All vehicles entering the country henceforth must meet the decibel limits set out. If they do not , even if the exhaust is standard, they will be rejected.(ie they will never getto be sold here)

But the situation is different for vehicles already in the country.

Here is the actual wording of the rule

“2.7(3A) The noise output from a standard or repaired exhaust system of a motor vehicle in Schedule 3 that is operated in service:
“(a) must be less than, or similar to, the noise output from the vehicle’s original exhaust system; or
“(b) must not exceed the applicable maximum decibel level for operation in service in Schedule 3, when tested in accordance with the Low Volume Vehicle Code.
“2.7(3B) The noise output from the exhaust system of any other motor vehicle must not be noticeably and significantly louder than it would have been when the vehicle was manufactured with its original exhaust system.

Note the "or" that I have highlighted. If the exhaust is standard it must not be (significantly - note "similar") louder than when new - whatever that loudness may be. Or pass the decibel limits.

If you are being told that in service original good condition OEM silencers (ie ones which are not noiser than when new) will fail WoF then I believe that you are being misinformed and I would be happy for BRONZ to seek official clarification

EDIT: From the LTSA Q&A

It is estimated that five percent of standard vehicles (approximately 130,000 vehicles in the New Zealand fleet) tested on the tail-pipe noise test are above 90dBA, but these standard vehicles will continue to be allowed to enter, and operate within, the New Zealand fleet, provided they have passed a recognised overseas noise standard and have not since been modified.

I beg to differ, I can see by your reaction that my comments do actually cause negative comments from you. But it's the old saying, and water of a ducks back to me. Sticks and stones blah blah blah mate.

You enjoy your HD, it has the same thing in common with the rest of us on here. That being, it has two wheels. I have some good cobbers that ride HD,s I often ride with them. So it's not the fact that HD's piss me of, and also heaps of other bikers.

It's the noise that the brainless few make with drag pipes on, it's not even a nice sound. It's just an ear shattering noise, likened to a jack hammer at full song.. You other HD riders should have a word in these clowns ear hole. As IMHO they are only drawing attention to the rest of you HD riders. Also the rest of the biker fraternity!!

Well that's my two penneth's worth. Now "you" to enjoy the rest of the break.
Cheers
Huck

So where do you stand if the outside of your muffler is standard but the inside has had the baffles changed?

I don't think it will exceed the 95 decibel limit though - what rpm do they test noise level at?

**Motu** · 26th December 2007, 10:37

It's not what you think.it's what the guy doing the WoF thinks.Make sure he thinks your bike sounds just right and you'll be sweet.

6 db = 2x the noise

True.
They sound like sewing machines.
It's karma for all the sewing machine comments they made about Jap bikes in the early days
