Noise levels at M.O.T
Has anyone ever encountered problems with noise levels when M.O.T'ing?
My setup is dual flowmasters(one silncer per side) hooked up to a set of headers and its reet loud....
If I had to fit a quieter set up, would I loose performance?

As long as you have a full exhaust system I don't think there is any law that specifically states how quiet a system should be.
However I believe that if the noise level is considered a public nuisance then you can get a pull for it.
That is my understanding but there are members here with a lot more knowledge in this area than me.

I have a 3" system with morosso silencers fitted just b4 the tail pipe,sets off car alarms as i drive past in town,if i fire it up in Sainsburys all the car alarms sound off..its very loud but i have no problems with the mot,i think alot depends on the tester,been pulled by the police a couple of times,both times just to look at the car...

The way I read that is if your car is pre 1970 there is no sound limit and as long as it actually has a full exhaust system and as long as the silencer has not been "altered" then it can be quite loud as long it is not open pipes and the noise level reduced "as far as may be reasonable" by the silencer.
One way I would interpret "as far as may be reasonable" would be to say that any quieter and the performance and fuel efficiency of the vehicle would suffer if the silencer were more restrictive.
Or to put it another way. If I run around on open pipes it would not be unreasonable for me to expect to get pulled.
But if it is only as loud as a Bus or large HGV I would not expect to get pulled.
Then there will be a grey area between those two points on the scale.
