About Modified Exhaust Campaign ...A campaign against deliberately modified exhausts on vehicles installed mainly for the purpose of increasing noise levels, a seemingly pleasurable activity for some members of the community who clearly have no consideration for the disruptive effects on everyone else. The low frequency noise created travels further than normal noise and cannot be effectively reduced by barriers.Update!
Good news for Australia - the Commonwealth Government has introduced new laws, referred to as ADR 83/00, reducing the noise levels of new on-road vehicles. The laws appear fairly complicated, partly due to the 4 year phase in period from 2005 to 2008, but the upshot is that all new on-road vehicles will be subject to lower noise emission limits than in the past.
There are 3 main problems with ADR 83/00 - firstly it only applies to new cars, so it will take quite some time for the effects to become noticeable. Secondly, it doesn't apply to off-road vehicles. Thirdly and most importantly, it doesn't prevent people from modifying the exhausts of their vehicles - the states need to introduce separate laws to prevent this, and maintain vehicles within 5 decibels of initial noise levels. So far only NSW has done so.
If you live in a State other than NSW we urge you to contact your State MP and ask them to introduce similar vehicle noise legislation to that recently introduced in NSW, effective from 1/3/08. To view this legislation, go to http://www.environment.nsw.gov.au/noise/poeonoisereg08.htm
