does anyone know what the legal db reading is for road?

Im pretty sure there isn't, its quite a grey area.

Road cars have to be type approved for road use when being homologated, and this is stated on all vehicle V5 documents that the car as it came from the factory is to an acceptable level.

It should say something like DB approved or DB Limit Acceptable.

The police can choose to pull you over and advise it is too loud but this only occurs with 99% of aftermarket exhausts and not factory exhausts, same goes for when going for an MOT. If the car is too loud they will fail it because it is not to the same set up as when the car was homologated initially.

Feel free to put me right but i'm pretty sure this is correct.

The only place where we enforce DB limits is on race circuits

HTH

To Add: When a car has to go for an SVA is has to be less than 102db a meter up from the exhaust

Looks like the limit is 82db as just seen this on the MLR http://www.suffolk.police.uk/News+And+A ... hausts.htm

Thats ludicrous. Good luck to the factory Ferrari F430's Lamborghini's and so forth with the butterfly valves that are too loud for circuit driving now as standard. Weather or not they are modified.

Be nice if the police could focus on other real elements of crime rather than this. This sort of thing really bugs me.

Another money spinner for Gordon and his, hopefully temporary, gang of robbers.

Looks like I'll be receiving a fine then!
My Blitz Nur Spec is pretty loud....

I think they should fine the stupid little kids on their stupid little mopeds who constantly go around my estate.

that's complete logger, my Shelsley passed as road legal on the SVA at 98db so I'd be sticking two fingers up if they tried to fine me! Plus, the test they discribe sounds very empirical whereas the sva and track tests are taken x m and xx angle from the exhaust at about 2/3rds max power or rpm
