Loud pipes....damn loud!

[Jantar]

...What has not been considered and IMO is a fault is they have no allowance for automatically passing imported pipes that pass a lower standard. For example: I could spend $1600 on a set of Leo Vince slip-ons for my bike which pass EU standards (with quiet insert) which are a lot lower than NZ motorcycle noise standards, however this would not be recognised here.

Um, I believe they have...

A vehicle will comply with the new law if the noise from the exhaust system is similar to or less than the noise from the exhaust system that was originally fitted when the vehicle was manufactured

Yeah but I also know of WOF places that will fail any bike with a pipe that is not the original fitment on the presumption that it is louder. Despite the pipe being EU stamped.

And good luck arguing with the WOF man that the new pipes you have fitted are 'just as quiet' as the stock ones you removed.

We see enough cheap Chinese lamps with EU markings - you expect us to beleive an exhaust complies just because it has an EU stamp? Or that mufflers haven't been tampered with? The provision is in the regs to fail for non OE exhausts...it is there for a reason.

So do you also fail OE pipes as a matter of course because they may also have been tampered with?

The test is "if the noise from the exhaust system is similar to or less than the noise from the exhaust system that was originally fitted when the vehicle was manufactured". And you can use your subjective judgement on that standard.

Fair enough.

Not intending to be an arse - interested as I'm building a pair of mufflers (and prefer not to shell out $150 on compliance), but in reality, as a bike guy checking WOF's just what do you do a bike with a non OE muffler?

Hold out the meter or use your own judgement on what sounds OK?

Also, how does the WoF tester know what was originally fitted to that bike? Surely they'd just have to go by the noise level. That said, checked at a predetermined RPM on, say, a single, a V-Twin, an inline four is going to produce a different volume isn't it?

I just had a cunning plan, In involves my pipes and an EU stamp.

It doesn't matter what's on your pipes: if a polis thinks they're too loud, you'll have to have them tested.

I know a guy with an RC45 who made his own muffler (very nice it is too!) The custom endcap is stamped the same as the factory ones, completed with "92dbA". He still has to button off on tracks in the US with sound booths, as he goes past. Probably because it's considerably louder than the stamp says it is...

Yeah, I was making a funny.

LMFAO, I do laugh at my own jokes so its cool.

Getting a WOF is the easy part, Its the doing a U turn and burning rubber because the cop has been listening to your approach for 5 blocks that gets tricky.

Now I'm laughing.

It reminds me of a incident many years ago around Cheviot. A mate of mine was pulled over by a police oficer at the bottom of the hills and told he was getting a ticket for speeding as the cop could hear him winding it out through the hills.

It was a loud bike, but 25 years ago no one gave a shit about the noise.

He got off the ticket by writing a short letter.

I miss my drag pipes. Can't afford to change pipes on the new girl yet. Too much else to do first.

Rosie. I had my Dyna mufflers modified by a mate (http://www.jonsshed.blogspot.com/) in Dunsandel. They're not just drilled out. He took the internals apart and just kept the perforated tube, put a wider end piece in, an kept the wadding around the outside. They're now like looking down performance mufflers and sound really deep but not loud at all (well, I don't think so). Cop that gave me a speeding ticket the other week didn't seem arsed about them anyway. Might be worth considering if yours are of a similar construction. I think he charges about $100 for doing a set.

Thanks for that. Had a look at the site but can't figure out how to contact him. Not very computer literate. Do you have an e-mail address for him?
Cheers.

Are there pics of the new bike?

I must have missed them.

That's it in my avatar. More pics on my profile page. Have some changes planned but will be doing them slowly as finances allow.
