The time has come!!!

Well we have all heard about the Mufller & sound level etc for motorbikes but it is now become a reality !! . Mate went to take has Aprilia which is fitted with a compelte Twin muffler TigCraft system on it to the local shop for a WOF so thought he'd just book it in & while doing so was told that they wouldn't give the bike a WOF or any other bike that has an after market muffler on it ?? . If it isn't standard factory fit then no WOF . They had given him a Wof 6 months ago with the same system on but no go now . He hasn't got a standard system for the bike as it had the Tigcraft on when he brought the bike . This is going to open up a massive can of Whip Arse I can see . Not to mention the fact that I have a " Not for Highway use " Akrapovic race muffler on my RSVR with no standard can to swap it over for Wof time either . So finding a standard one has now become a reality as well .

Well what the.....?

Wof at mates places from now then? But that's a short term fix...

Can someone here who works in the industry please comment?

Hope such stuff doesn't catch on here. Luckily I have the standard gear, but still what a hassle swapping the yoshi and then....... what a waste of life. Bastiges

Just got my WoF
States that the sound level can be no louder than standard muffler.
The bike shop has a different form than the garage for the WoF.
Nothing about how loud the stereo can go though

Surely it is a noise issue? Not a matter of being factory original?

And a WOF issuer would know the sound level for every make/model out there, how?

they probably dont have the measuring equipment and dont want to be responsible for giving a warrant to a bike thats too noisey, or dont want the agro of telling the customer they need to book an expensive noise test.

who is the shop? lets kick them in the balls.

Sadly they say that wont cut it . There are mufflers that are quiter than standard but clearly put Factory or no WOF they don't want the hassle any more obviously .

Vehicle Inspection Requirement Manual

Motorcycles

11-1

Resons for rejection:

6. The noise output is noticeably and significantly louder than it would have been when the vehicle was manufactured with the original exhaust system.

This is nothing new. Aftermarket pipes are not banned. At a guess, your mates bike is loud? There's a better than even chance that the same man who said he doesn't give bikes with aftermarket pipes warrants, would have done so if it wasn't outside of the regulations outlined above, as he probably wouldn't have given it a second thought. In other words, stuff the muffler full of chickenwire mesh before you go for a warrant

So, what theyre saying is you have to source a genuine exhaust for say, a 1940s Vellocette to get a WOF for said bike?

Huge Tui momment.
Tell them to grow a brain cell, and stop being wankers.

So how is that gonna work with original parts that have been er....debaffled?

**idb** · 21st July 2007, 15:41

As far as any of the garages around here know, Contis were standard fitment on all bevel-drive Ducatis......what's a bevel-drive?

A couple of months ago I had the Darmah at the Nurburgring.
You can have a couple of laps for 10 Euro (from memory, not that reliable).
The guy came out while I was lined up for my lap and wasn't going to let me go as they have a 95dB limit and they had measured mine at over 100...and I knew I might be on the limit so I had been trying really hard not to rev it too much!

After a big sob story about having brought it all the way from NZ he relented and let me have one lap only, and only if I promised not to go too hard!!!

Hehe.....100dB....I call them my "Hey, look at me everybody!" pipes.

just get a muffler quitener thiingy like what the boyracers use

theyre legal and if installed and make it quiet its ok.

**shyboy** · 21st July 2007, 15:52

u really need to go to another wof place. only bikes we turn away are bike with straight pipes and no attempt the baffle the sound. anyway a wof is only good for the time of issue. boy racers swap tyres with there mates to get warrants.

Will report back on Monday what I have found out.

**Grahameeboy** · 21st July 2007, 17:03

I have Arrows on mine. Coleman's passed mine as they fitted the exhaust and I have a Certificate saying they comply with EU regs with the baffle in but it is held in by a circlip anyway so easy to put back in and you would not notice any difference in noise level, just the tone.

I think if you buy an exhaust that does not have EU compliance or a removal baffle (not one that is DIY removed) you are safer...I know EU does not have any jurisdiction in NZ but it has got to be a better defence.
