wipper Posted July 30, 2007 Posted July 30, 2007 Does anybody know if there's a legal Db limit for road car exhausts? Recently had a new box fitted and it's measuring 94 Db which I reckon sounds too loud at some revs! Anyone? Quote
stu999 Posted July 30, 2007 Posted July 30, 2007 SVA limit is 101db. Nothing to worry about if it has measured 94... Quote
Blatman Posted July 30, 2007 Posted July 30, 2007 Never seen a noise meter at an MOT station either, and I've presented some pretty loud cars and bikes over the years Besides, 94dbA is pertty quiet... Quote
perksy Posted July 30, 2007 Posted July 30, 2007 Errr mines definetly more than 94bd Too quiet and you can't annoy the Maxpower Drum & Bassss Nova boys Quote
Blatman Posted July 30, 2007 Posted July 30, 2007 Nor set car alarms off... and on my street, one of the house alarms as well Quote
DIY Si Posted July 30, 2007 Posted July 30, 2007 I've MOT'd a car that even I thought was a bit iffy, and I have a bird engine with just a middling sized Micron race can! The car (my mini) is much louder than the 7. I could even be heard 2 miles away when I worked earlies! Still fine according to Mr MOT. Quote
wipper Posted July 31, 2007 Author Posted July 31, 2007 Had this back from the Cheshire Police with regards to legal noise levels. They're saying 86 Db is the legal limit???!?! The sound level measured in accordance with 5.2.2.2 to 5.2.2.5 of this Annex, | (a) in the case of vehicles with engine power of less than 75 kilowatts, shall not exceed 84 decibels | (b) in the case of vehicles with engine power not less than 75 kilowatts, shall not exceed 86 decibels. | Quote
RICHARD+PHILIP Posted July 31, 2007 Posted July 31, 2007 it's not April the first already is it! Quote
Mid life crisis Posted July 31, 2007 Posted July 31, 2007 Best not drive my car in Cheshire then, 103db Never had any problems at mot time though Quote
darthurs Posted July 31, 2007 Posted July 31, 2007 I've driven mine home 40+ miles with no exhaust at all before now passed a police car and he didn't even bother. Dan Quote

Buzzer Posted August 1, 2007 Posted August 1, 2007 Is the police figure an average weighted figure and at the roadside? SVA is at 1 meter. 94db I wouldn't worry. Also I remember seeing TVRs having to fit additional silencers to get under 98dbs at a track day last year. Dave Quote
