Interesting read this one, but be prepared to have brain fade after about 1 minute. 

Worth persisting though but in small doses

Certainly highlights many issues re exhaust systems, wonder which office will hand ball this one. I still think that when legislation is offered it is almost always full of "Grey Areas" keeps the lawyers in business..........nice find though as the pipes on my VFR sound like a small block, very deep and meaningfull ...

The exhaust thing (plus other ADR items) isn't that hard to work out. If one wishes to replace the OEM exhaust with an aftermarket one then it must meet the ADR requirement ( or other standard) in force at time of vehicle manufacture. If the OEM exhaust has a cat convertor (under ADRs) then the aftermarket one will need one as well to remain ADR compliant otherwise it can be defected.

Noise

The amount of noise a motorcycle can produce from the exhaust outlet depends on the year it was manufactured. If it was manufactured after February 1985, the acceptable noise level is 94 dB(A), but if manufactured prior to this date, then it is 100 dB(A).

The noise level is tested with the engine operating at a steady speed and, depending on the type of engine, the engine speed will be between 2500 rpm and 3750 rpm

If modifications are being considered you must ensure that the vehicle's ADR compliance is not compromised by the intended modification.

Motorcycles manufactured after July 1975 are built to comply Australian Design Rules (ADRs). These design rules cover various aspects of the motorcycle such as brakes, noise and lighting.

Motorcycles that comply with the ADRs, and were manufactured after October 1977, are also fitted with a compliance plate. This plate is mounted to the motorcycle's frame, usually in the head stem area.

If a motorcycle is certified to comply with the ADRs it must continue to comply with those rules. If modifications are being considered you must ensure that the vehicle’s ADR compliance is not compromised by the intended modification.

Fines cannot be issued if an exhaust is “optional equipment” because the term is not used in any of the relevant laws.
No court could accept that any police officer has “sufficient expertise in the fields of acoustical or sound engineering” to determine noise levels in accordance with National Stationary Exhaust Noise Test Procedures for In-Service Motor Vehicles. “A defect notice issued on the basis of a police officer’s subjective judgment will not sustain a conviction”.

I'm sorry but that usually isn't the issue. Police Officers under the Transport Act have the right to defect a vehicle / issue an infringement notice if they believe that an offense has been committed. It is then up to the owner to prove otherwise which usually involves court and/or inspection station attendance, possible legal fees and in some cases expensive engineers certificates. Either way they can really cause considerable grief and financial loss if they choose.

I am aware of one person that had his car defected and attended the local Gov. Inspection Station to be told it was OK and had the notice removed. Then a week later was defected for the same item despite his protests.

I personally had a trail bike defected that was 100% OEM as the Police Officer thought the rear mudguard was too short.
