I lived in Prees for 11 years, a centre for huge motorcycle meets.
Silencers do restrict Gas Flow, which affects the performance.
There is a way round this, expensive purpose built systems.
Many had them and good luck to them.
They are completely different to the local pillocks who remove the systems on small under powered bikes and who cause a problem to all.
A slightly louder exhaust in a rural area with very fast roads is not an issue at all.
Prats who remove exhausts on 50cc machines and rev them to the max in an urban area are.
It is all about respect for others.
I have never got annoyed at powerful bikes zooming past me on fast rural roads ridden by those who know what they are doing.
Good Luck to them.
I get seriously pissed off at the local yobbos with no silencer, tax or insurance driving like idiots with no exhaust creating chaos.
There is a world of difference between fender and others riding powerful bikes at school time, they do so slowly and carefully, as opposed to the young prats who put people at risk by driving like idiots with no exhaust to try to impress the girls.
…You can remove the stock one and replace with an aftermarket less restrictive one, but as per a car, you can’t legally drive without one at all. You’d go above the legal noise and emission limits.
I’m sure they really do think they are on a race track. They rev and destabilise their cars before taking the corners at high speed. We live in a town where there are children, animals and the elderly. Apparently it is reported to police regularly but nothing is done.
Thank gawd NSW has laws specifying motor vehicle noise levels:
Motor cars
For the purposes of section 136 of the Act, the prescribed level for a motor car of a particular type is:
(a) in the case of a motor car of a particular type that is not certified to ADR 83/00, the motor car’s stationary noise level must not exceed:
(i) for a motor car built on or after 1 January 1983—a stationary noise level of 90 dB(A), or
(ii) for a motor car built before 1 January 1983—a stationary noise level of 96 dB(A), or
(b) in the case of a motor car of a particular type that is certified to ADR 83/00:
(i) if the compliance plate date of the vehicle is on or before 1 September 2011—the greater of the following:
(A) 90 dB(A), or
(B) the noise level established by ADR 83/00 for a motor car of that type when stationary plus 5 dB(A), or
(ii) if the compliance plate date of the motor car is after 1 September 2011—the noise level established by ADR 83/00 for a motor car when stationary plus 5 dB(A).
and there are fines associated with them
Selling a vehicle that, for example, has noise control equipment that is inappropriately modified, defective or missing. = $300/$600
Using a vehicle on a road or road-related area that exceeds the prescribed noise limit by:
less than 5 decibels $150/$300
5 to 14 decibels $250/$500
15 decibels or more $600/$1200
Apologies if this has already been mentioned - I scanned the thread first and didn’t find a mention:
‘Acoustic cameras’ tested in bid to cut noisy vehicles
The Department for Transport will test noise-detecting cameras in various locations over the next seven months.
The move comes after pressure from campaigners in rural communities who say some motorists illegally modify vehicles to amplify the sound.
Much like the way a speed camera works, if a microphone in an acoustic camera detects a vehicle breaching legal noise limits, it triggers a camera to take pictures of the vehicle registration number and any other relevant images to allow a fine to be sent out to the vehicle owner, the government said.
The noise level deemed to be inappropriate is yet to be decided.
Obviously, like the use of speed cameras, this will be unpopular in many quarters but will it combat vehicle noise levels … :?:
They have had them working here for years there is one on Mount Ousley on the way into Wollongong BUT like average speed cameras they only apply to trucks.
I heard about these cameras on TV this morning. the trouble is, I suppose they will all be sited in the cities where they will bring in most revenue, not out in the sticks where the yobs are running riot.
