So is it basically - your car must be under 90db unless it came louder from the factory, then it must not be more than that figure?

that is basically what i have been able to work out. it would be great if i could find a car that is registered as this and i could then set precident that my car is "reasonable".

I would take your car along to local VOSA staton ask them to check under controlled conditons VOSA should have fgures for vx220 that WAS suppled with vse as a vauxhall warranted option Surely If data not available, then there is nothng to measure against I would also like to know when the 4500rpm conditon was defned, I doubt 1986

[jules_s]

And what's to say a 10 year old car on an OEM exhaust wouldn't be louder than one with zero miles anyway?

4.5k was taken from 2/3 of full throttle which is what they measure at apparently

Maybe we need to know what this act defnes rather than "apparently" says

Correct, this is what i am going to try and get to the bottom of "guidelines" is what i was quoted at and I asked to see the law. I am going to take a trip down to the station and try and find where these "guidelines" that I have broken actually become enforcable and that they are able to issue a fixed penalty or get a conviction.

If it's of any help I have an na with standard exhaust and on the few trackdays I have been on it measured about 85db (4.5k rpm at 0.5m)

vosa measurements would outweigh raw roadside data as long as to your advantage

Over here it's 340 euro and car papers can be confiscated (thus car also). You then have 28 days to fix it back to max 2db over factory db. Still no idea what factory db is though.

The law int he latest amendments states:

CONTROL OF EMISSIONS
Silencers

54.—(1) Every vehicle propelled by an internal combustion engine shall be fitted with an exhaust system including a silencer and the exhaust gases from the engine shall not escape into the atmosphere without first passing through the silencer.
(2) Every exhaust system and silencer shall be maintained in good and efficient working order and shall not be altered so as to increase the noise made by the escape of exhaust gases.

and

TABLE

(regulation 55(3))
1 2 3 4 5 Limits of sound level Item ( a ) Vehicle referred to in paragraph ( 1 )( a ) ( b ) Vehicle referred to in paragraph ( 1 ) ( b ) ( c ) Vehicle referred to in paragraph ( 1 ) ( c ) Conditions of measurement Method of measurement Requirements for exhaust device 1 Limits specified in paragraph I.1 of the Annex to Community Directive 77/212. 89dB ( A ) 82dB ( A ) Conditions specified in paragraph I.3 of the Annex to Community Directive 77/212 Method specified in paragraph I.4.1 of the Annex to Community Directive 77/212 Requirements specified in heading II of the Annex to Community Directive 77/212 (except paragraphs II.2 and II.5).

damn, the above should be formatted as a table, basically it says 89db( a )

thanks for that. It does give me something to work from.

Hmmm, of course the other part of the equation is the position of Milltek, Tullett, Larini etc in this situation. I'm guessing that, unlike the VSE, it doesn't say 'for track use only' on every product that they sell?? I'm more than happy to be corrected by somebody who has a better grasp of the law than I do, but surely there must be a serious liability issue here if you are sold something for a road car that makes you liable to prosecution if you use it?

[rob999]

Sorry to read this Dave and its the first time I've seen this enforced. Lesson I have learnt...stay away from Suffolk!

[techieboy]

I'm quite shocked by this, as I had no idea that it was an offense, never mind one carrying a fixed penalty notice.

It's always been an offence of one form or another, it's just a lot more likely to be enforced now. A friend of mine was issued with an ASBO for the exhaust on his Ferrari 360CS in Leeds about 5/6 years ago and had to immediately remove it. He sold the car instead.

Having just done some bits on a local members standard exhaust equipped 2.2 VX, I'd say that's about spot on. Couldn't believe how quiet it was (mine originally came with a VSE before embarrassment got the better of me).

First one I've ever heard of. Not heard a VSE in person but doubt mine is much quieter, yours surely isn't either. Considering how loud some TVRs and Porkers are I'm shocked I've never heard of this before.

[VX-GT]

Paragraph 1 suggests 89db but (3) Instead of complying with paragraph (1) a vehicle may comply with Community Directive 77/212, 81/334, 84/372 or 84/424 this defnes the method of test more research required by davemate

[VIX]

This is a all a bit of a worry. All these things that I've been sold which seem to have made my car illegal. It would have been nice to have been warned!

The original Accessories brochure states:

"The VX220 sports silencer has been specially designed to provide added performance for trackdays (not for use on public roads)."

Edit. PS So what was the penalty?

So stuff it with wire wool,demand a re test under controlled conditions,pass the test then pull it all out
