Exhaust Noise - Decibels

[Steve ( West Mids )]

Is there a legal limit, or a noise pollution limit that applies to exhausts?

I'm thinking in terms of say Construction and Use, Council Noise Pollution or just ordinary PC Plod?

I'm asking for a buddy on another forum who has loud pipes on a classic car. I know there are rules to do with modifying the exhaust system on a new car to make it louder ( 6 inch nails in the back box ) but are there any hard and fast rules with decibels anywhere?

think 94dbls is the max doesn't brunters stop you running with an exhaust louder than that anyway

There is for motorbikes which I think is 93dB(A) and 3/4 max revs at 0.5 metres.

Don't think there is for cars though.

There are no specified limits - it's all very subjective. To give an idea, my IS is 85dB @ 2m and the Tubby is 90 dB (which sets off car alarms)

Not surprised 90dB is called "the second action level" of the Noise at Work Regs, your employer has to provide ear defenders and you have to wear them

To give an idea of scale the Tubby is nearly 4 times louder than the IS.
