Re: Loud exhaust legal things question
 

DT is correct that C&U does specify noise levels.

However ikn to to test for compliance there is also a proceedure, I cannot be bothered to go hunting. I used to do compliance testing many years ago in a different profession. This require not only static but moving tests as well, and also stipulated the environment in which the test was to be conducted.

Chances are that plod would not know how to use the meter, have it correctly calibrated, have the test proceedure, have the test environment or the skill to conduct the moving test.

So they will probably simply look for the correct E marking to show compliance with C&U and no indication of tampering and leave it at that.

Andy your question fails the whole europe type approval and therefore in breach of C&U

They wouldn't even need to measure it with a db meter,If you were stopped and it was spotted they could ticket you

Re: Loud exhaust legal things question
 

Has to be an exact distance fromt he vehicle though, and thats the part the police will never know the laws on, so they can't officially use the db reader to do you as they won't know. Its quite hard to find the exact laws and EU guides on noise. Thats why i'd always argue it, as its an opinion, not a factual law. If you ask them to show you the specific law, they would have a real problem showing you it.

Depending on officer, it ranges from.

Let off
£30 fine
Stopping you from riding your bike any more as its not legal.

I've suffered the middle, but didn't have my baffle it, but its an official exhaust. If my plate wasn't slightly illegal, i'd have fought it as its marked with an E mark and a road legal exhaust. I'd have claimed it never came witha baffle from factory, but its a road legal exhaust.

In fact, my standard system is actually louder on idle than the factory upgraded exhaust, its just the factory upgrade is a good few db louder in the mid range revs.

Re: Loud exhaust legal things question
 

Not sure but I thought this E marking of an exhaust was no longer valid. Regards to an exhaust passing or failing an MOT, is this now not down to the opinion of the tester as to if it is too loud or not?

When I had my stubby ART non legal race can on with no baffle or packing in it, the tester gave the throttle a bit of beans and then said no problem. I didn't actually hear him say this as my ears were still ringing and bleeding. But the pass certificate told me what he said.

Daimo, I have published the figure here a few times. However, the easiest place to get the info is the government published fact sheet on motorcycle type approval

What the fact sheet does not say is how to conduct the tests. for this you need to read the individual directives.

If you are a vehicle research facility, these types of tests are bread and butter.

Re: Loud exhaust legal things question
 

And here is the problem. Vosa requirements for an MOT do not match the requirements of the eec directive. If you look at the link I posted you will see that replacement exhaust are also bound by the requirements. So whilst yo do not need the stamps to get an MOT, Mr plod can still do you under C&U.

However, my tester views a loud can as an essential safety feature. The vosa requirement does not measure the noise, instead it is a subjective assessment not to be louder than a compara ble motorcycle. So place it alongside a second bike with a lounf after market can and it is no different so pass

Re: Loud exhaust legal things question
 

Sounds like if everyone went along with the loud cans saves lives we'd all be in the clear. :)

Re: Loud exhaust legal things question
 

Very clsoe to what I jsut said though isn't it? Can find the noise regs, but actual regulations on the testing is much harder to come by??? Of which no police officer will really know, so cannot fine you as they cannot do the test, so its an opinion of theirs only.

That is unless that forward you onto said research facility, but realisitcally, would they go that far?
