This is obviously another jealously/fun tax on people who have loud and fast cars or bikes. It must be, cant be about noise pollution because the vast majority or cars on the road have pretty quiet exhaust. Infact road noise from the tyres is far louder yet these things cant possibly be set up for tyre noise because everyone would get pulled. Hence fun tax
There is an existing EU programme to reduce tyre noise. A Google should find it. Noise pollution is not that funny if you suffer from it, I don't currently.
Its funny how people are prepared to go noisy in other peoples neighbourhood but tone it down in their own street.Why would that be - cowardice?
Load noises are fun and there is plenty of scientific evidence of the pleasure generated however in an increasingly densely populated country perhaps the unsocialable should get on a track, speedway, etc and amuse each other.
Don't get me wrong I love the sounds of TVR's. Astons etc but in the right place. And just in case you are wondering my car does north of 155mph
That's exactly what I was trying to get accross, in other neighbourhoods it seems its cool to try and impress the 15 year olds by making lots of noise, but when in your own area you take care and are considerate, double standards.There is an existing EU programme to reduce tyre noise.

If someone made a load of noise in a car while you were putting your kids down, you'd call it inconsiderate and probably have a post on here about your neighbour or whatever, but at times that suit you you're happy to make as much noise as you like, do you see what im getting at?
It'd be a good thing to reduce noise levels from cars, and if it is done correctly it'd benefit a lot more people than it'd hinder.

That means R888's will be banned then as they are right noisey buggers....lolThere is an existing EU programme to reduce tyre noise. A Google should find it. Noise pollution is not that funny if you suffer from it, I don't currently.

Funny story. I was parking in a public car park and reversed up to the back of a BMW and my exhuast set the car alarm off. (I thought it was funny anyway). This was an Evo with HKS Superdrager exhaust (as standard) and decat.I get seriously pissed off at those anti-social t

Also I think most 'loud' cars here would probably be fine, and the fact that they are taking 10 seconds of video infers they are after those who just sit and idle, not those who are loud on a drive past.
I think you've interpreted the 10 sec video wrongly. I believe the video is to make sure that the offending car is caught on camera (as it may have hit the noise threshold slightly before or slightly after the place where the camera's pointing). Plus even chavved up cars generally make more noise with the exhuast while accelerating than sat still, even with a big stereo.
I'd welcome this just to get rid of the knobs on the scooters round my way with the go faster exhausts on that ride around at all hours although i'd be shooting myself in the foot for the times that i'd want to take my bike out.
The law is there now at the MOT for bikes, when mine went through last year it had a bs marked can which was quite loud, it went through, this year despite the markings i had to take it off and put the standard one back on.
Impreza was much louder i had, 3" turbo back system with 1 silencer in the system, never any problems with that

I have often why they can lay some road surfaces which produce almost no tyre noise at all, and others make a bloody racket.The section of the A90 which has just been re-surfaced, (OK, a few months ago no), is like driving on a carpet of air, then suddenly on to the old bit, and the sound is terrible.
Guess its rocket science.

No, but it may damage your hearing. http://www.guardian.co.uk/science/2007/aug/23/scie...

I was talking with the guy who MOT'd my bike a couple of weeks ago & I quizzed him on exhausts & number plates. He said that a lot of the rules have recently been suspended & left more to inspectors interperetation. At the moment!!!
A motorcycle silencer used to have to display a BS number, now it must not have "Not for road use" on it and must sound reasonable. If the model of bike is known to be loud under normal circumstances then as long as the aftermarket exhaust is similar then is is OK. A bit random!
What if your bike passes an MOT then you do 10,000 miles within a year, the packing gets destroyed & the exhaust becomes too loud for the roadside cameras. I've failed noise tests on the race track with a standard exhaust before now. Quiet days are usually 97db which I think goes for the road as well.
If this law is to catch individuals with their exhausts hanging off then OK but anything more will come in for a lot of stick.

Good links, but no revalations there really, Noise Induced Hearing Loss has been know for years, good reading nevertheless. tks for link.
Yes, it was more the deaths allegedly caused by traffic noise, though, and Tegwin's comment that "They cant tell me that "noise kills".."!Tony*T3 said:
Unfortunatly most 'tuning enthusiasts' put 'sports' exhausts on their cars/bikes as their first 'upgrade', despite the fact that they have no idea wether it actually improoves their stboxes' performance. It just sounds louder. This puts them clearly in the league of antisocial retards imho.
not louder, better! Don't go around actually stating its because its louder, thats just a side effect, its because it sounds better, and puts a bigger smile on your face.tboxes' performance. It just sounds louder. This puts them clearly in the league of antisocial retards imho. Everytime my dad and I go out in the T350, I always end up with a grin the size of a banana, pops and bangs so much on the overrun and almost anywhere else too after we fitted the JP sports box.

However further observations - noise is merely a form of energy and as such noisy exhausts are probably just wasting energy best converted into motive power - I can understand producing more noise because there is more exhaust where breathing and throughput has been drastically improved but as most exhausts dont do this (and they dont)then alot of the noisy exhausts should rightly be binned.
I thought that first bit too, so I bunged* a turbo into the exhaust pipe of my 2.0 zetec. It's actaully really complicated about exhuast pressures and such like. In a normally asmatic car you need to restrict the exhaust a little so that you get what is called back pressure, it is this back pressure that helps exhaust gas scavenging from the cylinders. At WOT on a NA then you want as little back pressure as possible. On a turbo you want as little restriction as possible after the turbo. Which remind me, I must remove the one remaining silencer now that I got rid of the two cats.- OK much more planning that a simple bunging session!

Same as speeding init? Local village wants blanket 20mph and have even made their own signs "20 is plenty", yet get someone right up your ar$e and eventually overtake (at 30mph), sure enough they turn into a driveway in the next village along.Do as I say, don't do as I do.
I wouldn't be suprised to see them in the UK soon. It would be too much of a temptation for our 'wonderful' government to resist hitting the motorist with yet another tax/fine.
Agreed, it would be nice to reduce the number of corsanovasaxo106's with a family sized baked bean tin for an exhaust and the damn scooters that sound like a wasp on speed.
Yes, I have a 3" bore turbo back system but it only hits 92db. I don't think noise should be an issue unless its excessive. But then the definition of excessive is open to debate. I have both friends and family with louder cars than mine but none I'd say are excessively noisy. I love the sporty noise some cars make (especially anything that says 'TVR' on!!) and it should NOT be yet another target.

most of you are missing the point that the "performance" exhausts that you see 16 year old kids using on scooters are already illegal.
to ride a ped at 16 it must be restricted to 30 mph, once a performance exhaust is fitted it is no longer restricted.
so a 16 year old with one will be riding illegaly and will have void his insurance.

i've just done a search on the source of this story and it seems that pistonheads has managed to leave out some of the facts.
the noise cameras are for commercial trucks and are being used to enforce regulation against engine compression breaks, they will not be used for cars but can easily be expanded to include loud subwoofers, noisy exhausts, or even an inopportune honk of the horn - to quote from the article.
