some jealous neighbours or d1ckhe4ds can give EPA a call and said to them: "Oh I know this car with loud exhaust plate no...."

or "I saw this car blowing smoke out of the exhaust" (although it's a freezin cold morning and your exhaust smoke is white which is water condensation which should go away after your car warmed up - they dont understand this coz they're such a moron)

Any of these jerks call the EPA, then you'll get a notice, any scum these days can do that one phone call just to annoy you.

So was it for noise or for gas pollution?

i got done by some coppers for too loud! took it to an exhaust shop, gave em $5 and they tested it-- 93 Db close enough

then send them the form --- thats if they didn't send you to the pits for it!!!

..you have to know who it is..

I think the way it works is if its a member of the public they have to have multiple reports. If its a cop they just have to report you once. It was probably a cop.

Half the time they have absolutely no idea what they are doing anyway. I was reported, but mine was a nice and legal 89db so i had to do the run around for no reason.

Compliance is basically just to say that the car meets Australian safety standards.

Same as an engineers certificate.

Both are issued to say that the car is safe to be driven on the road.

The EPA doesn't have anything to do with safety issues, it's a matter of pollution, either air, or noise.

And instead of "innocent until proven guilty", with the EPA, you are guilty until you prove yourself innocent.

:D

Yes, but to be registered, the car also has to meet all emissions and other standards. Its a dubious one, but as the cop wasn't there to explain to him (e.g. refer him to the compliance plate date), there isn't too much you can do.

Don't stress about it at all.. the stock exhaust is way under, and so are many aftermarket exhausts. Mine is full HKS Super Dragger II system and its fully noise legal.

You go to an exhaust place, 10-15 mins they do the test, you pay your $30 and they clear it on the spot. You continue to drive carefree.

Just got to watch how they test it some of them stick it right up your exhaust to check it, they have to be a meter away on a 45deg angel on the opposite side of the exhaust and I think it's up to 4000rpm they test you at and most of the time it's on back off that's that's when the DBA climbs.

just got back from the test- took 5 mins...

"The noise level emitted from this vehicle tested at 3,200 RPM was 87 dB(A).

Accordingly i am satisfied that this motor vehicle complies with..... in that the noise emitted... does not exceed the max. permissible noise level of 99 dB(A)."

so i was well off, even though i watched it click 91dB...

stressed for nothing ey...

I just pulled out the EPA defect I got in Apr 02 and it states that the limit is 90dB at 4800rpm. I got this defect for a reading of 92dB measured .5m from the exhaust tip at an angle of 45deg.

I shouldn't have looked this up cause now I'm pi$$ed off again.

There is no difference when it comes to doing a DBA test they should do it all the same.

I reckon they should leave as alone and pick on them dam Harley's. Maybe wee should all wear leather jackets and call our selfs Hell's Sky's and do a charity run once a year works for them.

4,800 rpm is a bit excessive.... I was under the impression that they had to do the reading based on the speed of a vehicle...... Which is 110kph MAX. (aussie law)

So if you do 100-110 at 3.2 - 3-5 that is where the DB measure SHOULD be taken.

5,000 rpm in most car's is loud at the best of time's......

(i read the EPA testing stuff off this website....)

Yer but.. there is something about OR 3/4 of the maximum rev range in there..

it all varies to be honest depending on where you take it. Everybody hears different things..

Mine was tested at 5200rpm.. and had to be under 90db at that range.

    • You know, that is exactly the thing that I was thinking a coupe of hours ago. I even had a plan for a meme, involving one big one, another big one, and the Old El Paso girl saying "¿por que no los dos?"
    • NoS, 2 of the big ones.
    • Oh, that's grim. Something bad has been happening there.
    • Put an endoscope down the hole and saw this. Not quite all around the bore but a good 60% at least. Chin to the chest and towards further disappointments I guess.
    • 2 does "sort of" applies, maybe......but looking at what parts would be needed for the swap to get engineered, registered, and insured, and basically that's everything under the car, the modifications the make it legal would be problematic and horrendously expensive, all for a street car that just cruises around and hits a few twisty roads on the weekends Also, from looking at the NSW rules and Regs, with all modifications that is required just to make the car safe and not twist itself to pieces, and then actually get registered for street use, may still be impossible nowadays As for 1, when you add in a fresh engine, fresh transmission, rear cradle and diff, tailshaft, suspension, brakes, cooling, and all the other fabrication required, your probably looking at up to $100k to do it right, all for a 20 year old MX5 that is over engineered and you would never be able to actually use the power it has on the street, much like your beastie, which I love, but you actually track that thing and can use all of its powers in anger, in a safe environment  Hell, the old Bogan Cruise Ship had more power than I could use on the street, and in hindsight, I went a bit silly on that thing, it didn't really need the 500hp it had for what I actually used the car for, it was fun, but basically unusable on the street if you value your licence  As for cams, yeah, I'll probably book it in for them to get installed and tuned soonish, like next month after MX5 Mania are back at work....... and yes, I've already sent a email to bin the turbo quote and quote instead to install cams and a new Fluidampr balancer that will suit the 2.5 better than the OEM 2.0 balancer that is swapped over for the 2.5 install, as the balancer needs to get pulled to time the cams it's a while your in there sort of thing I did think a bit about flex fuel for a laugh, but being na, and no where really around locally anymore to get E85, I've binned that idea, so no sweet sweet corn smells are set for the car I wish E85 was more of a standard fuel, it's better for the environment, better for tuning, plus that sweet sweet smell we all love As for fitting in the family, that's not needed, as everyone in the family already owns a car that can seat 5 humans comfortably enough, the MX5 is "my toy" As for buying a car that is already built, nah, I would rather pick and choose my parts, I enjoy the process, and in the big picture, the additional cost is well worth the enjoyment, and the occasional frustration, I get out of doing it, albeit with other people spinning the spanners, and me, just paying the invoice 🤣
