measured on concrete or grass? in a building? in a playground? in a field? all of these make a massive diffence and are why a specific dB level is simply unenforceable.

I Got pulled at the weekend for a noisy exhaust, the police officer was kind enough to tell me that it was a 90DB Limit and i was 114... in a Nissan Pulsar Gtir with a Cat back Exhaust tbh i think it was B****ks! My Clio is louder and that whipped through a 98DB Sound Test at combe, Now my Car was never Built in Europe and was imported with the Exhaust on it And you'll never See or find a Direct replacement system for one,
I Recieved a £30 fine (to pay the officer his wages) and was then informed my exhaust was too loud and then he Recommended i got it changed as it was illegal and if pulled again i risked a court appearance...
I would Have thought i would have got a VDRS for this instead of a Fine and "Get that changed" Bit unfair i think, However i cant afford to argue it in court, so will have to pay the Fixed Penalty,
Im Changing the 5" Dustbin on the Back to a 3" pipe anyhow as it looks Chav, Hopefully this might Tame the noise down, Exup Style exhaust valve or a Plug lead off next time wink

Worth trying.

Go to local station armed with the ticket and ask to see the specific construction and use regulations that say that.

When they are unforthcoming ask to speak with the duty inspector and point out that the test was not carried out as per the legislation (I am guessing the car was not tested at 7.5m on a 50kph drive past?)

Also point out your car was imported and tested in the current condition.

You may well find that the ticket is ripped up.

These scenarios really do smack of certain officers/forces trying it on.

But be sure that the vehicle is legal in all other respects and that your paperwork is in order - Streaky

Noise complaints are rising fast. In the USA and some parts of Europe, they have managed to ban motorcyclists completely from some neighborhoods due to the popularity of fitting noisy cans. In Switzerland, noise is kicked into touch by very very low speed limits in towns. As a motorcyclist I agree that they are now too quiet, but once again a few spoil it for the majority. The reason bikes and indeed many cars have become too quiet for some peoples tastes, is because of the idiots that have gone before. If there had never been any exhaust modding and quite frankly idiots taking the piss, we would still be stuck with 1970s sounds, instead the average car has louder tyres than exhausts, yet there is some irony that cars are become more powerful yet still quieter as speed limits drop.
This thread seems to contain the very people who are going to be responsible for the next set of noise laws. Eventually this will lead to no modding of vehicles at all (or jumping though hoops like in Germany), or very low speed limits, let alone modding exhausts.
The UK is way behind other countries, but boy is it going to catch up. I guess the modding manufacturers will be the first up in arms, but at the end of the day many of them are just targeting the same demographic as the 'No fear' clothing label.

At what point is the DB rating measured?
Tick over or redline or other??

No longer a boy racer; small car, loud exhaust (TVR 390SE); as to the other, SWMBO and ex-mistresses can testify to the contrary.

But I know what you mean about the rest of them wink .

Exactly - everyone here quotes dB's as though that menat anything. At what rev/min and at what distance is a minimum requirement before anything can be specified.

The trouble is, I'm absolutely certain that the legislation will be applied to the Aston Martin, Lamborghini and Ferrari fraternity as well as the Chav Nova/Saxo brigade. Now I love the sound of a Ferrari/Aston V12 at full chat and I'm guessing pretty much everyone else on here will too, but the Gumint won't write the legisation with manufacturer/engine type exceptions so the beautiful wail of a Ferrari 355 with Tubi exhaust will be just as illegal as Spotty Nige's slammed Nova with 5" can.

Be careful what you ask for, you might just get it and realise that it isn't quite what you thought after all, by which time it is far too late. I don't want the Government given public license to pass any more legislation to regulate how I live my life or enjoy myself, they have done quite enough of that already. Now just let me pass this to the Government's official censor and get permission to post it.

Noise limits for vehicles are set at a 50kph drive past test at a distance of 7m (from memory)

The tests that people are debating here are carried out at the roadside/MOT station and bear no relation at all to the manufacturer test.

There is no scope for altitude, surrounding infrastructure, background noise, cows farting or squirrels sneezing as they pass.

To my mind, unless challenged a precedent will be set that will prove hard to revoke.

Still, I now live where this isn't an issue so really don't care wink

Hmmm this topic reminds me, I'm sure I read a story once somewhere about some jobsworth who complained about a modified Evo/Impreza/something like that being too loud and asked the owner to rev it while he put his dB meter next to the exhaust. Owner spots an opportunity and revs it up, and produces a bit of flame on the overrun - cue a rather startled dB-o-man and a slightly singed dB meter.

If the Evo in question was fitted with a Motec ECU with the anti-lag option enabled, I'd be surprised if he didn't scensoredt his pants and have his meter torched! laugh

Well I always understood it as as long as the car is not really loader than it was before then its ok.

Thats fine by me, my car, being rear engined, has an exhaust tract about two feet long with a little bean can silencer on it. It is loud, was loud and will always be loud. Not like you can fit a cat, mid box and back box on in the space of 18 inches lol!

Be nice if they applied noise limits on car stereos.

Do these Chavs really think we all want to listen their tripe when they drive their little cars down the streets.

I always chuckle inwardly knowing that in 4 or 5 years, said chav will almost suffer from irreversible hearing loss laugh

Silly me, guess thats goes in the same thread as fog lights, look at me, I am cool. biggrin

Sorry to revive a dead thread, didn't see the point in starting a new one though.

Does anybody know if laws have changed at all regarding exhaust noise?

I have just removed the mufflers on the back of my bmw e63 650 and it is brutally loud, I looked around at every video I could find but not one video, or even the one I've taken shows how utterly angry it sounds.

No idea how many dB it is.

I don't get how 'normal' cars are restricted, but the likes of a GT3, GT-R, 458 Speciale aren't???

I hope they never stop proper cars making a proper noise! Sadly, I fear this isn't the case, especially with the bks "no more ICE cars by 2040"... weeping

I believe that after market exhausts now need to e marked, this would be an easy way to introduce requirements on silencing performance but will not help with stuff that is already fitted.
