Car Exhaust Noise
Discussion
One further thought - honestly, does your car sound noisy to you? Would it sound noisy to your mum? If the answer is anywhere approaching 'No', take the car with you to court and if it comes down to a matter of is it noisy, ask the magistrate to have a listen. Might just make them think that it would be fair to do so. They mainly do have brains.....
But then, my TVR Chimaera sounds loud at 90dB in a quiet street.....until you follow a T350 with no cats and a sleeved exhaust.....then it sounds like I am driving on tip toes.

Yup - thought my S3C was loud until I followed a Tamora with a fruity exhaust. I thought my engine had stopped

Still not had a reply to my asking to take them to court over this matter, 
Hmm - maybe the CPS will decide it not worth persuing! 
FYI - Found out that my GT3 produces 104-105dB under similar conditions to your test and with the exhaust flaps open in "Sport" mode - anything up to 114dB and mine is Euro approved!!

that or they are waiting on the authorisation for spending £50k on a few weeks 24hour surveillance to gather evidence that his car is noisy FYI - Found out that my GT3 produces 104-105dB under similar conditions to your test and with the exhaust flaps open in "Sport" mode - anything up to 114dB and mine is Euro approved!!
yes, it WAS you in Sloane Street etc on Thunder in the Tunnels that I did have in mind!.....
Today I stopped to have a chat with one of my sons old school friends who has a 1.4 Civic, and he told me he had been done for excessive exhaust noise. So I was interested to hear his experiences on the way his test was done by our inept Norfolk Police road traffic officers.
He was following a Police Road Traffic car for about 4 miles before the police stopped in front of him and demanded to test his car.
He was taken to a local village hall car park ( gravel & grass) and asked if his car had an exhaust ? which he said "of course" then he was asked if he had a working speedo & rev counter? "Yes" he replied. He was then asked if his ignition worked ? By this time he sarcastically said yes.
The Police officer then said he was going to conduct a noise check on the exhaust.. Test instruments were set out in accordance to ISO5130 then the officer stood directly behind the car exhaust and asked my sons frient to take the revs upto 5500 RPM and hold it, which he did for two tests. 78 & 79dB which is a pass. Then he was asked to take it to the red line and hold it for 10 seconds. This he then told the officer he was unhappy to do, The Officer then said that his car would be impounded if he refused the test.
He reluctantly and with protest did as the officer asked. 86dB. The officer then told him it was above the 82dB limit and slapped him with a £30 Norfolk Police Beer fund voucher.
To make things worse he had a sticker on his car which said "I'd rather push my Honda than drive a Ford" which was for a bit of banter between him and his mate with a Zetec Fiesta. The officer took offensive to this sticker as he said he drove a Ford. My lads friend then queried the fact that the Road Traffic car was a Volvo, but the officer said that he had a Ford at home on his driveway. and he was to remove the sticker or be slapped with another offence of discrimination.
Unfortunately being an 18 year old naive driver, he payed up the fine, but said that he didn't agree with the way the officer dealt with him. The Central ticket office said that they would look into it, but have heard nothing back. Also the ticket the officer gave had a phone number on it which has not been used by Norfolk Police for over 2 years.
This really annoyed me that the bloody Police can do this and blatantly get away with it, and before you all ask, I still have not heard anything back about a court hearing with my little brush with them over exhaust noise.

Not BS at all, I saw the ticket which was issued. Seeing first hand on what Norfolk Police actually do on their exhaust noise tests and from talking to people who have had their vehicles tested it wouldn't surprise me if there were other similar stories.
They tested mine at 5250 RPM when it should have been 3750RP so anything is possible.

Has anyone on here actually been fined for a standard exhaust that would be over 90dB? I don't know, for example say.... TVR 
I know mine is registered as a PLG, but not sure if that has any effect on the regs. I just can't see how they could require you to make the car quieter than when it left the factory!?

IIRC someone on the Clio Trophy forum was stopped for a check by a policeman as he had an "obviously aftermarket exhaust, as no car comes out of the factory with the exhaust in the middle".
Apparently not.
Nor does the E-Type, the Mini Cooper S....
He was asked to produce his insurance cover note showing that his car was insured as modified on this basis.

I think I read the/a similar story on here.Apparently not.

Twas when the 182 first came out - the officer obviously knew a bit about cars and thought it was a modded 172, since it was the V6 cars with central tailpipes.
A little knowledge...

If that story is true, it's proof of yet more police b/s. My car is insured with all mods declared. The cover note/certificate has no such information recorded on it. Indeed, that has been the case for all the modded cars I have been driving during the last 40 years.Apparently not.

I know people make inappropriate jokes about Norfolk and turnipheads but.....
