    And how noises are defined by horribleness depends on the individual.

    ...and, you know, the law and stuf...

    Do we in the UK actually have a law regarding maximum decibel volume like in NZ? If not, that'd be lovely.

    Some people say if an MOT inspector deems it as "too loud" it won't pass, but I'm not convinced and seems rather wooly, anyway...

    There have also been crackdowns in the past where they've pulled people over under noise pollution laws iirc.

    The law is for the level of noise emitted, not the way the noise sounds.

    The laws on exhausts are rather complicated with lots of grey areas.

    For the MOT if the exhaust is deemed "unreasonably louder than standard" then it should fail the MOT

    As far as legalities
    Construction and use regs say it is illegal to modify the exhaust system on a car to make it create more noise.
    It doesn't seem to cover removal of the standard exhaust and replacement with another exhaust that makes more noise as standard.

    There are noise limits imposed on brand new vehicles. This covers the "drive by noise" of the vehicle so it includes engines and tyre noise.
    A device is used to measure the sound.
    The problem is, for consistent and accurate results it has to be done under very strict controlled conditions.}
    Some police have the device also, but the grey area arises when the vehicle in question doesn't have a tachometer to measure engine speed and the police can't replicate the controlled conditions.

    Most cars have a noise limit of 90DB, but certain sports cars (Certain VXR Vauxhalls, TVR's ect) had a higher limit allowed for them, but i can't remember what the value was.

    because they don't sound anything like a chav'd up clio, saxo etc

    Hey now! My Clio runs on ITBs and a finer sound you won't hear in anything less than a 4.5l V8 ;)

    Pfft, stuff your exhausts.


    None of you sound as classy as me on my push bike with a piece of plastic shoved under my mudguard ;)

    You need to get some of those clacker things you used to get in cereal boxes to put on your spokes, then you'd be top dog.

    How can an obnoxious mechanical roar sound good at any time? :(
