Exhaust Laws In Qld  

memmi87

No cat is illegal, having no mufflers is illegal as well afaik...

Rancher

No. Pre 86 cars dont have to have a cat. Mufflers are just for noise as well. So long as your car is no louder then 90dB, then it'll be fine.

TwinCam16

Kinda..

It's not having no muffler that is illegal.

It the lack of muffler causing you to go over the permitted levels for noise.

Then there is always the OTHER fine they can slap on ANY modified exhaust system "Exhaust fitted with reduced efficiency"

TwinCam16

Fuck, beaten.

Rancher

Getting old.

memmi87

I know about pre 86 cars, but the guy is talking about a VL, so having no cat would be illegal.

Kai

My car is 77 model. With a 93 engine. Do i comply with 77 or 93. I assume 93?

clutch-monkey

curious as to this too, i always thought in this case you had to comply with '77, the car itself

astorey

Speaking of exhausts in QLD, someone recommend me somewhere to get a zorst for my s13 on the goldie

johnjohnmulley

as far as i know its the engine. my 72 model has 89 engine and i run a cat........ and apparently older cars (forget what age, i think pre 77 or something) are allowed to be 96db , doesnt matter what engine, and all other newer cars must be 90db. i know this is useless without links to the actual website but hopefully someone can back me up here with a link.

astorey

I think it's pre 82 that can be 96db?

TwinCam16

Correct.

Kai

According too a engineer i know this is correct.



Ive heard this alot too. Im going too go search too find it in writing.

clutch-monkey

let me know what you find kai

Kai

Shane is right as per usual.

sweet, good to know.
cheers tincan and kai!

zannon

the actual law is if it had push rods then it can be 95Db anything else is 90Db.

I swear to fucking God if I ever find out who you are, I am going to beat you until you stop posting in a many-month old thread with incorrect information. Judging from this, I may be better off beating you to death.

As much as I hate to disagree with you Shane, I'm going to have to on this one

As per section 133 of the Transport Operations (Road Use Management - Vehicle Safety Standards) Regulation, all vehicles with an internal combustion engine must have a 'silencing device'.

A motor vehicle propelled by an internal combustion engine must be fitted with a silencing device through which all the exhaust from the engine passes.

Also just to touch on OP's question regarding the legality of running no cat, perhaps surprisingly it may indeed be legal for a VL to be sans cat.

The requirement for all vehicles to have a catalytic converter was only introduced on the 1st of February 1986. A limited number of VL's were built in January 86 and believe it or not there are a handful of 12/85 plated VL's getting around. 12/85 and 01/86 plated VL's, to the letter of the law, do not have to have a catalytic converter fitted.

In any case, OP will still require a muffler.

what would we do without you...

alpharx7

khubner are you in there. please for the love of god i hope you're an only child.

khubner

i swear it's not me not even i am not that stupid.

trev084

Pretty sure Zannon would fucking annihilate you, just saying.

810 OUT

even though old post... what you dug up is right kai, my car is a 64 and i have to go by the engine for exhaust db. i thought the legal limit was 92db though?? and the rest of the car also has to comply with the adr;s that your engine came out of.. to do it legally anyway. i had to fit 2 speed wiper motor, retracting seatbelts, demister etc

hotburgers

i think it sounds like zannon and the random hero need to go 1 outs!

All VL Commodores were built to comply with ADR37, they all must have a cat. This includes the late '85 builds.

Even though this is an old thread, for those that are wondering the same thing, don't be a cheap ass and just buy a decent high flow cat. It's not going to affect the performance of a shitty old engine anyway.

xxxxgold

VL's were manufactured to comply (including the 12/85 and 01/86 builds) simply because it wasn't practical to build perhaps a couple of hundred cars only to have to make significant changes to 02/86 onwards vehicles. It was similar to the VZ's prior to the Euro 3 standards being introduced, although they came into effect on the 1st of January 2006, a fair chunk of the late 2005 V8's were were fitted with the L76 instead of the LS1.

Just because the early VL's were built to comply doesn't mean that you will be defected for running no cat, any VL built prior to the introduction of 37/00 may be driven with the cat removed, provided of course all other standards are adhered to.

nferno

I only have a resonator and my car is pre 2000 so its fully legit

97caprice

I will reword that a little differently.

All VL's must run a cat as they all comply with ADR37/00. This ADR was listed on the vehicles spec plate for all VL's.

I would assume you are correct otherwise. The OEM's were aware somewhere around the begining of '85 of the intended introduction of the new ADR for emmision requirements, hence canning the old 3.3 and going with the RB30. It would not make sense to set the RB to run under the earlier ADR then change only two months later. This is also the reason the V8 was not released in the VL range until late '86, they simply could not get it to perform and meet the new ADR's, eventually they got it better than the VC/VH/VK 5.0 but performance just wasn't what it used to be with the red engines.

xxxxgold

I'll admit to not having the faintest idea what a spec plate is, but regardless of whether a vehicle is built to comply with a particular standard, if the standard has not taken effect as of the build date of the vehicle, legally that vehicle does not have to comply with that standard/ADR.

Certainly all VL's were manufactured to comply with 37/00 (to my knowledge anyway) but the earliest vehicles fell outside the scope of 37/00 (in regards to catalytic converters).

In modifying a vehicle (in QLD), as long as the ADR's, TO(RUM-VSS) and Code of Practice are adhered to, the modification is legal. Vehicles need only comply with the 37/00 CC requirement if they were manufactured on or after the 1st of February 1986, exempting the early VL's from this requirement (despite the fact that they were released from the factory with a cat). Nothing in the TO(RUM-VSS) prohibits the removal of a cat from a pre 01/02/86 vehicle (even if fitted from the factory) and as the COP doesn't apply in this instance, a 12/85 or 01/86 VL may quite legally have the cat removed.

This doesn't mean that you wouldn't be defected and fined, you almost certainly would, but if the matter was contested in court, you would be successful.

corkey

you have to comply with 93

97caprice

The vehicle must comply with all ADR's it was built to originally comply to. Altering the emission control system causing an increase in CO2, NoX etc above the OEM listed ADR compliance will result in a defect. No you do not have to run a cat, but you are not going to get the emmisions low enough to pass with out one.

Imho, it doesn't matter whether the ADR was not in effect until 02/86, the vehicle was built to comply with the forthcoming ADR and must continue to comply. Spec plate is the one in the engine bay that list's all the ADR's the vehicle was built to.
