UK Law on Modified exhausts

Recommended Posts

According to the law, you cannot have any modifications to your exhaust system that makes it louder than standard.

 

is this enforced? as I'm sure most Subaru owners would be breaking the law based on this. 

 

sounds stupid to me, I can see why they would have a sound limit but to limit it against itself seems ridiculous and pointless. 

 

just wondering what I can say if i am ever pulled over by a jobs worth, also anyone had experience in this?

I think it means modifying the exhaust...don't know if it counts replacement ones like performance ones as technically it's not modified from how it was made...however I may be wrong but I doubt police would enforce it but VOSA may as police have better things to deal with...unless you have a straight pipe I wouldn't worry about it to much

Well mine was 85db to 90db on tick over according to my phone app. And is pretty loud Dan and a few others have said they can hear me coming. I even Shake alex's windows when I go past his house. And never had a problem I've had aftermarket exhaust on just about every car too :D

Never had an issue, most cars that are in the mod world have been changed at some point....... I had a Mk2 Escort standard 1.3 engine and exhaust system ripped that out and changed it to a 1.6 twin 40's and an Ashley race system to a 2 and a 1/4" from the manifold back!! Lol never got any problems.

Agreed with above tho, if you take the 'hiss' and sit outside poor Doris's house testing the revs and backfire then I'm sure the cops might have something to say!!!

All in moderation and respecting the surroundings Villages to SantaPod raceway we just need to know what's right for the right times!

all my neighbours told me they sold their alarm clock when i got my first scooby lol .when i passed test in 80's and was a boy racer(still am a heart really  :D )people said you could get done for exhaust being 2 loud then,but as said popo dont bother unless your being a dic and p them off then they could get funny,mostly traffic cops that can be funny about it.once had a traffic cop tell me he would inpound my fiesta rs turbo and take it apart nut by nut to find stuff wrong becouse i was being a young smart ao,so best to be nice and polite and they sould be ok with you.

I read somewhere that you cannot be pulled for noise from an exhaust if it has been bought off the shelf. You also cannot fail an not on noise. So, if you buy a performance exhaust off the shelf and fit it without modifying it, legally you are ok. insurance declaration is a whole other issue as are your neighbours. Just don't go blasting it up and down the street

There are no official manufacturers figures, so you can't be done for louder than standard, what they can do you for is noise nuisance.

 

Also they change the wording,

 

It’s illegal to modify the exhaust system to make a vehicle noisier after it has been ‘type approved’ (checked it meets environmental and safety standards).'

 

they can also hit you under section 82.

 

prob cos im getting old but i really dont want an ear bleeding exhaust

Sounds like i should be fine then, 

 

there are louder cars than mine that have no issues, i think if I am polite and come across as a nice person to any cops I may meet I can't see them bothering with the hassle over it. 

 

Thanks guys :)
