Was on wheeler dealers when they built an ac cobra replica because it had to have an sva test and he was saying the limit is 100db, just make sure when the fuzz arrive the car is warm or it will give a higher figure!

No chance of borrowing a bolt on tailpipe noise reducer for a day?

If your back box hasn't got a baffle in it, but some wire wool and stick it in, we'll reduce it slightly

iv,e borrowed a bung that brings it to less than a 100 but makes it gutless, i spose the only permanant fix is a scoobyworld resonated centre section

Once they've been take it out again, they should give you a slip to say it legal, so just keep that and if you get stopped again just show them it! A bit dodgy but its one option!

Are you sure about that 100 db limit? I have never seen a figure on any of these threads! Noise is not tested on a mot so why would they revoke your MOT?

As far as i know on the road there is no number set in stone, It kinda comes under `Anything changed from OEM` could be deemed to be illegal, For an SVA test its different as that is a test to put a new car/build/import etc.. on the road, This differs from an MOT test for instance and on the road is different still, It all comes down to the tester and if its a VOSA tester he say its wrong....change it. I once had an advisory on a MOT for a noisy exhaust, I asked what to do and MOT tester said nothing leave it as it is and i`ll give you an advisory for it next time if you still have it fitted

Chuck some wire wool and a bung in it until he`s tested it and gone
Then get a resonated center to quieten it down a bit

And what about all those motorbikes that sound like jet planes???

It's a limit that is set by vosa, but it's grey area about been in the mot! It is the moters descresion to wether he thinks its to load or not! But defo 100db was on wheeler dealers at a sva test!

Noise is also massively affected by climatic factors, I don’t see how a road side check could ever be legal?

Some cars have got to be way over 100db from standard (im thinking some of the V8 super cars?) Are you telling me they are illegal from the factory?

Smiffy8800

It is 100db for sure warm the beast up first tho. Damn police got nothin better to do! Good luck resolving this

thats what i said , ferrari lambo massarati tvr aston you cant tell me they are less than 100 at 4000rpm, i did try pointing out that 4000rpm is over the speed limit so a bit pointless imho

wrx_jim

100 db is illegal, it has to be less than 100 db measured at 3500rpm @ 500mm distance.....

Smiffy8800

Let me know the outcome of this please I can't see mine being below 100db so be good to know incase I ever get the tug over it

Method of Inspection:-"During all parts of the emissions test relevant for the vehicle, assess subjectively the effectiveness of the silencer in reducing exhaust noise. Note: For vehicles not subject to an emissions test, the engine should be revved to around 2500rpm or approximately half maximum engine speed if this is lower."


Reason for Rejection:- "A silencer in such condition, or of such a type, that the noise emitted from the vehicle is clearly unreasonably above the level expected from a similar vehicle with a standard silencer in average condition"

that is what we testers use as a guideline bit of a joke really there is no set guideline for the mot so i dont see how they can void your currunt mot cert...... friend of mine had a preducer for a insecure batt and was told to get a mot station to sign to say it had been fixed...... its not even a mot failure lol

I got tested @ 116db a while back and was fined £80 and told to get it changed, The officer was a grade A **** and kept asking if all the mods had been declared on the insurance (which they had).

After reading into this someone said they cant do me as subaru did not publish any info regarding a 96 jdm wrx's db levels

It might have been mentioned but it has no relevance to your situation unless your car is having an SVA test rather than a noise pollution(sec 59) test

PS, The track at Elvington, York has a DB limit of 98db now

well i never got a ticket just a verbal invitation to attend station for testing tomorrow or they offered to come to my house anyway i gave them my phone number and carried on to tesco

When I had my old classic WRX with a straight through exhaust it failed its mot to which was expected. When I looked down the failure sheet apart from silly little things they also failed it the db level. When I asked what they were on about, they told me that because it wasn't standard it was then too loud and that they would fail it again if it wasn't changed.
I thought they were taking the michael and called VOSA. They told me there was no limit and it was up to the mot stations discression.

Hope you get a decent bloke tomorow and not one of those ar5eoles that are about

Most harleys and other bikes are stupidly loud so much so that you can feel the sound vibration on your chest. If that can be legal surley they cant pull u for any impreza exhaust
