Ok with the increasing bullshit with Police blitzing I want to diagnose my exhaust Db myself and keep the device in my glove box.

Should I ever be unlucky and be pulled over for inspection I am going to video the Police and record all their suspicions for perusal for my lawyer.

I will insist on an on the spot test with my device to illustrate my awareness.

I hope the Police will encourage my actions.

What is the distance for the microphone off the exhaust outlet.

I've read 1 metre, 525mm,... seems to be no constant clear instruction.

How does the government expect us to conform with laws that aren't clearly stated.

Anyway,

I'm one not to back down.

I'm 43 years old , have spent probably $43000 on my car, and will not quietly cage it.

I've had my car since 2001 and haven't one infringement.

So far I've been left alone and I respect the Police for that.

I don't want that to change.

There it is..

Last time I checked, it was 1m, at 45degrees of the exhaust tip.

Unfortunately, I suspect police will think along the lines of, "yeah, use HIS gauge, pfft, he must have tampered with it."

Hope this helps.

It wont make any difference what you spend. You dont even hve to be stopped to be directed to the DECC. Notices can be mailed to you after Police, Council, or even a member of the public contacts the DECC. They send you a notice of directed inspection and you front up or cop a fine.

If you are stopped and it is a case that they believe your vehicle is loud etc, then it is merely that. They dont have to be experts or carry the equipment. That is what a defect notice or DECC notice is for. To send you to an expert who has the testing equipment. In the end the actual testing criteria is very strict and depends on aa lot of factors that most people gernerally wouldnt kno or be able to test for. Simply put it is 90db for a new car and 96 or an old one.

Why dont you just contact the DECC for the detail and even book it in for a test.

You could even spend less by reading this document from the DECC.

      I would think making the argument that the travel is limited by a spring flexing against a spring perch as "the same method". Later on in the document they do state that the spring can't bind on full bump travel and cannot come loose in full rebound travel as well. (which is all very sensible). The laws are actually pretty sensible and reasonable. It's just that the people who enforce and check them don't actually read them or know them accurately. "Oh, coilovers? Instant fail mate. Don't even need to look at it." - Guy who will be instantly reported by me. There is probably merit to people who do get defected for height also get defected for the suspension in that state that allows it. I did never consider the people who are complaining about coilovers being picked on are also running around at 50mm off the floor.

      Ethanol Content Sensor - Always at 11%?

      I think given SAU's knowledge of E85 we can strongly conclude that 10% ethanol in almost any situation is entirely fine. Almost all of the myths against E85 were overblown, let alone E10.

      From your link See bold text, is this referring to damper settings, if so that may a issue for "some" inspectors, I cannot see aftermarket coilovers having the evidence that "must be available that its functional performance is equivalent to the original" Maybe just remove the adjustment knows and hope for the best???? Meh 5.2 Suspension travel In all instances, modifications to a vehicle’s suspension must ensure the integrity of the system and not compromise the ride quality. At least two thirds of the original suspension travel should be maintained in both directions (rebound (i.e. extension) and bump (i.e. compression)), and rebound must be limited by the same method used by the vehicle manufacturer or if this is not practicable due to the nature of the modification, an equivalent method. If an alternative method is used, evidence must be available that its functional performance is equivalent to the original.

      They actually don't - They adhere to VSB14 rules just like Victoria. The rules are against CABIN adjustable height, and it quite clearly states that the height has to be within parameters. I asked the VASS engineer to confirm this when I got my car engineered and they refused to engineer the coilovers because they didn't meet the requirements for requiring engineering. (mine are height adjustable.) People "Not wanting to bother" with "Actually reading/knowing/adhering to the rules" should result in fines and immediately losing the ability to issue blue slips and/or RWC's in Vic.
