kite marks on exhaust?!
Discussion
I've been chatting with my father, who's a bit annoyed after watching a fly-on-the-wall police type thing. On the program, they showed a biker being pulled over for some reason, during the routine checks on the bike the policeman told the rider that his exhaust was illegal as it was not kite marked?!
He's a bit miffed as he's just spent 2 weeks building a custom stainless exhaust including 2 silencers for his car, but I think it sounds like a load of tosh personally - surely as long as the Db limit is not breached (which it wont be, he built it to be quiet as the car was too noisy) then where is the problem?!
So question is was the policeman talking a bit of billy or was he correct?

They should have a British Standards number etched on them (a sticker isn't good enough). A stupid rule as non legal cans are much safer when riding in a city. Saved my bike and a couple of idiot pedestrians who can't be bothered to look before they cross the road.
If I was him I would contact the people near him that do SVA's for kit cars etc. Explain the situation to them and I'm sure their must be a way where he can have the exhaust examined and assessed by them. If they deem that it meets standards then hopefully he will be issued with relevent paperwork that he can show BiB if he ever gets pulled.

Hmmmm. I've got an allegedly (and I believe it is, it's not noisy) road-legal exhaust on my bike. It doesn't have a BS kite mark, but it does have some sort of magic EU "E number" stamped on it that designates its legality for road use.

While we're on the subject, is there a Db limit/standard for car exhausts? I know about the bike ones, but do the same laws apply to cars? I fancy being noisy, but don't fancy getting busted for it.
I'd be interested to know too, my new car is
ing loud & TBH I don't fancy having my collar felt or annoying my neighbours too muchsva for kit cars says 101db measured at 3500rpm or if max powere developed at less than 4500 at 3/4 of that speed at a 45 deg angle to the exhaust exit at a distance of 500mm where the vehice is on an unobstructed surface of concrete or asphalt that extends at least 3m beyond all side of the vehicle

As far as I could find out, no.
Certainly, my car passed an MOT with a very very loud exhaust, and I've been stopped several times by el Plod for various things, and only one of them commented on it.
"I've pulled you for sounding fast"
"But I wasn't going fast though?"
"Errr. No. Can I see your insurance?"
Are you sure? The guy who used to service my bike had a shed full of standard silencers that he would swap around when it came to MOT time. He put alot of business through his local MOT test station and couldn't get it through with them turning a blind eye.
That was about 12 months ago.

Unless it's changed, the limit is 80dB measured 3 metres behind the vehicle (the road rally limit at scrutineering was 79dB at 3 metres, so we had to be quieter than a normal road car!).
80dB is fairly intense, by the way - my old MG's straight-through kicks out about 70dB and I don't have to use the horn that often...
(The dB scale is a bit odd - a change of +3dB = double the sound energy).
That's a lot of difference. Just wondering where a decatted Tuscan on carbon cans would fall.Isn't the SVA done at virtually zero distance from the exhaust though? pressumably that might make a difference? Dont know this, just remembering the SVA chap on that program where the vet built a cobra replica.
I'd agree that 102Db is quite loud - At one of the clubs I go to my RC heli's are only allowed to have a max of 55db or they are grounded, and they are seriously noisy up close!

AFAIK, there is not , and never has been a noise limit for road-going production cars. I have found nothing documented in the law. This is backed up by cases where the police have pulled people for 'excessive noise' with no need to measure the actual volume. 80dB would be exceeded by a large variety of standard cars, dependent on measurement rules, including ALL TVRs.
