For example if I drove my Elise (which is race setup) home form an event and happened to drive through "Operation Chav Hunt" there is a chance it could be deemed Noisy, as Im sure will many of our off-road vehicles, especially anything comp tuned.
Rather than the godawful noise a 1.0 Nova makes with a 4" bore exhaust running like a bag of spanners because of the loss of backpressure.
These boys are very silly. Basic physics states that noise is a form of energy. That energy has to come from somewhere, and if your car sounds like a bag of spanners and it's got anything less than a 3-litre engine under it's bonnet, you're going to be losing a couple of horsepower going down the street sounding like you've go no exhaust at all.Silly little boys. When will they learn there's no substitute for cubes?
Your quite right tough, My V8 Disco trundles along quite discreetly until i can afford to press the go pedal :twisted: then it "comes alive"
I personally have no issues with a specific noise level/test , at random or mot, as long as its sensible, Lets face it most modern Sports saloon cars have a "fruity " note to them
The Good Book says"No motor vehicle shall be used on a road in a manner which causes any excessive noise which could have ben avoided by reasonable care of the driver"Regulation 97 Construction and Use regs 1986.Interpret that how you want. I have issued tickets for making tyres squeal, loud music, revving of stupid bean can exhausts etc etc. I have to say that I usually take action after a warning has been ignored. Again the recent topic of seizure of vehicles can come into play.
Dont bike exhausts have to be EU marked or something?"
As people have siad TVR's leave (or rather left) the factory rather noisy so from a point of law surley noisy has to be quantified.

Finally I trust "propper coppers" but years go speeding tickets were given out by "propper coppers" who made decisions based on judgment and experience,
BTM , you are far more likely to get a tug for a dark visor( they make it far safer at this time of the year) and small number plate.
All this talk of back pressure is a bit old hat, what you're actually searching for is a tuned length, as any 2 stroke biker will surely agree. The manifold design and positioning of the first silencer is the critical thing the system after that does have an effect but the really important bit is that first length.Now back to the chavs - the problem I think comes from the turbo culture, with a turbo tuned lengths are hyper difficult to achieve and don't really have much of an effect, so you can just run the biggest possible pipe to shift the exhaust gases as fast a possible, so chavs see Scoobys and Evos running round with 4"+ systems and think well if its good for 600bhp on that it must be good for my 106/saxo/corsa/baked bean can.

squires has always been a biker haunt and quite often has a few hundered bikes and a police presence. I go loads and have never had any issues...
