Any exhaust on a car illegal?

Exhausts:

The vast majority of large or big bore exhausts are illegal for use on public roads. The fact they may have passed an MOT test is irrelevant as this only checks for exhaust gasses and emission legislation compliance.

Big bore and sports exhaust systems are usually fitted to increase the sound emitted and this contravenes the Type Approval of the vehicle, which is an offence. There is no requirement for police to measure the sound level from the exhaust system, it only requires an opinion that the system is not standard and that it is noisier than a normal vehicle of the same specification.

It is not an offence to sell these exhaust systems, but it is an offence to fit one to your vehicle and drive it on a public road. Motorists who do so would be reported to court and may face a fine and court costs.

My dads an mot tester, he informed me when I had my yozza Clio that if its any louder than the standard manufacturers noise output it's illegal, no two ways about it.

So the copper was right, pay your £30 and be done with it. People very rarely get pulled for this so it's slightly harsh but the policeman is only doing his job, no doubt be didn't like the look of you and it was an excuse to pull you over.

That's stupid. Just means manufacturers can charge what they like for original perishable parts and people have to pay it or their car is illegal.

Ive only just got it put on, I'm going to ring my insurance up this morning and declare it

Do you know what make the exhausdt is pal ??

Might be worth making sure it is actually road legal and find some documentation to show this before you do, that way your cover either way !!

I had the same thing happen.

It was all to do with did the car roll out the factory with this exhaust on it? No.

Does it have a kite marked stamped on it? No

Then it's illegal. Didn't get a fine though, just a vehicle defect form. Got someone I know to stamp it for me, and off on my way.

For pulled over a week later by the same cop, he didn't even mention it.

Seems an odd one. I remember searching online for days if theres an illegal noise limit for exhuasts after my neighbour had a big spaff about my old rover being illegal and too noisy. All I could find was that bikes had a legal Db limit and cars did not. And my friend asked an officer for me. And he got back to me saying as far as he was aware there wasnt a legal noise limit for cars so dont worry about it theres nothing my neighbour could do?!?

Won't solve anything, as it's still going to be over factory noise limit, and he can still fine you. Best of luck, hopefully you won't run into him again!

But it should have been declared anyway ;)

I had no idea exhausts were illegal

Fog lights - For vehicles fitted with front fog lights (rear fog lights are also included), it is an offence to illuminate them unless visibility is seriously reduced, which is defined as driving in rain, snow or fog with visibility less than 100 metres. Fog lights cause dazzle to other drivers and can attract a £30 Fixed Penalty Notice.

id love to be a police officer around here. The amount of pricks driving about with just fog on winds me up so much. I'd happily sit by the side of the road pulling people all day

Not really, the way I understand it is that if you fit an aftermarket exhaust, it's perfectly legal as long as it doesn't make the car louder than standard


how would road legal kit cars and cars like the subarenault on here fare? Since they're approved by the governing bodies but are built pretty much from scratch from aftermarket parts, what dictates whether they are legal or not?

So why don't the insurance companies say no we're insuring you with an exhaust on because it makes the car louder than factory standard. Seems like the police have a different set of rules to everyone else. Your right it should of been declared earlier haha

Its a sniper exhaust mate, didn't say it was illegal on the description when I bought it, it's not stupidly loud either, my mates vxr with the Remus on is so much louder and he's never been pulled for it

Unsure, I guess it's not down to them to check if something is legal or not (unless they have a crash - in that case they'll get out of paying out - and they've still had your money for the policy) - just look at the whole thing around decats :p

Been pulled a good few times about my side exit, told its illegal everytime but never got a fine. Just the usual 'that's illegal, take it off or next time we see you etc..'
 
Do WRC rally cars still link up the stages in the uk on the 'public highway'?

I was wondering this too.

I thought the rule was exhaust shouldn't be louder than it was designed to be i.e. to stop people drilling holes in them to make them louder. But if an after market was designed to be a bit louder then that would be OK. Seems like a grey area.

I agree mate

It's not a grey area at all, if your car is emitting any more noise than it was intended to from the manufacturer it's an MOT failure, thus illegal, therefor the police can fine you all they want.

Your insurance company doesn't care if you're breaking the law so long as you're paying your money.

When you declare mods it doesn't specify whether its louder, only if its performance enhancing, that's all that really matters among other more minor things about the personality of the person etc. Some insurance companies will actually cover stainless steel exhausts as standard and not something they can repudiate a claim from :) Induction kits and other bits are are a different story.

I certainly wouldn't say it's illegal (my opinion based on instinct, not fact) This can't be a grey area; EU has law for the shape of vegetables there must have been a law in relation this this before the Spanish Armada.

I'd hold out, I'm pretty sure if they were to fight it they would have to have evidence. "Innocent until proven guilty" hence why traffic ticket peeps take a photo, proof

So what law exactly is it that was broken?
 
This is a concern as I drive to all my events, I run a BTB Stealth with 182 Cat and both silencers fitted and it puts out 89db at 4500rpm, I'm insured with REIS and the car is declared as a Rd Going competition car running in Class 1B, I only inform them of changes if I move out of the class, looks like an easy revenue stream for the Police/Government, may give them a call just to ask where I stand.
I've not been stopped in the car yet but being old may be the answer to that.

That is an interesting read. Sounds like any exhaust louder than it left the factory is illegal although there is certainly some room to argue that the exhaust has not been modified but was designed that way.

It suggests top flight rally cars get single vehicle type approval, like a kit car I guess and thus are no louder than when they left "the factory".

It also sound like the police aren't actually capable of proving your car is too loud, due to the complexity of carrying out a reliable noise test. But it has never been tested in court.

Exhausts get noisier with age anyway, so it wont be as simple as "its louder than it left the factory" as in reality I suspect that a 6 month old car is louder than it left the factory if you could test it accurately enough.

Plus of course, do they actually have specific data saying what you exhaust noise would have been on the car when new that they can test it again? I suspect not.

So IMHO the bottom line is probably that they will test not against what it was as standard, but against what the noise limits were allowed to be at the time it was new.

IIRC its tested at 50cm from the tailpipe but at a 45 degree angle, where as for trackdays its normally the same distance but straight on, so I would expect the recorded value on a government test to be lower than on a trackday test, so even if your exhaust is slightly over at a trackday it may still be legal when tested slightly differently.

Yeah I know what your saying mate, he wasn't concerned how loud it was at all, he was just bothered about it not been a standard exhaust

Then he doesnt understand his own job, which TBH isnt exactly a very exclusive club to be a member of when you are a copper IME!

didnt bother arguing that much, only threatened me with 3 points so had to bite my lip

He had no grounds for giving you points, its this sort of blatant corruption that totally ruins the publics opinion of the police, idiots like that really do themselves no favours.
Shame cause although most coppers are obviously completely useless, semi-educated, self obsessed parasites who seem to do more harm than good there are actually still a few genuinely good ones in the job for the right reasons and they end up getting tarred with the same brush just cause the majority are bad.

I'm not sure I agree when you say majority. I would say in my experience they in fortunately in the minority.

The problem is that most people's day to day interactions with the police are car related. Traffic officers are renowned for being over zealous shall we say.

The vast majority of good officers that get tarred with the same brush are hard working professional people who always go the extra mile to help the public.
