loud exhaust

[2MPRSS]

i heard having an loud exhaust system is 2 demerit points.is that true?im starting to wory about doing mods to my car coz the cops are geting strikd by the day.am i just being paranoid?or is it true that all people with moded cars are gana get F%^*ED up by the cops and lose there license?

[SIKCVC]

it has to be over 95DB at like 1 or 2/3s of max rpm for the engine, and theres no points involved if you live in melbourne, just an unroadworth then you have to get it EPA tested... but man 95db in open air is HUGE!!! but if a cop doesn't like you, too bad. I t was proven on today tonight when an ex cop got done for it, he had it tested (well below) and he lost in court. I think in NSW there are points envolved since its not an EPA matter.

[2MPRSS]

yeh man it sucks broi just passed a blue slip test taking all my mods off and i wana put them back on but im hearing off mates that its like 2 points if u have a loud exhaust and to me thats a little ridicilous but its the law still im pissed :(

They'll give you a fine and a defect notice, to clear it, you must get a engineer's certficate which will cost $200-300, and drive to the RTA PITS.

Normally when I get pulled over, I'm really nice to the officer, if you're arrogant, wearing a cap backwards in a singlet etc, expect them to be more biased against you..

engineers certificate?man isnt that like illegal or something? what is an engineer certificate ?wat does it mean?

[XXpl0Sive]

Im not sure about the 2 points thing, but I can tell you that most exhausts installed here are over the NSW limit (90db). Police can be bitches and ask for a certificate. Yu need a certicficiate for any modification to a vehicle which affects the emissions/noise (ie. generally any non-cosmetic mod) etc.

So technically your exhaust is illegal without a certificate (and so is mine), but the cops dont usually care much unless you're a dick to them.

[XXpl0Sive]

Engineers Cert is a cert performed by an engineer (you can contact one from the RTA, they will give you phone numbers of engineers) saying that your car passes the standards set by the governent.

Eg. He comes to your house, performs the checks and then gives you a paper that says your car is roadworthy.

[2MPRSS]

ohhhhh i get it,but bro what if he knows its a defect and if he gives u the engineers certificate and the cops follow it up to him and fine him?isnt it like a blue slip if they let u pass it and they find a defect they go to the mechanics and they get fkd up 4 it? or do they just do it because they are desprete for money?lol

Well my exhaust is kinda loud, most of the car alarms go off when im in a car parking lot.

[XXpl0Sive]

I dont think its easy to find a dodgy engineer to give you a ceritificate cos if they get busted, they get fined and lose their qualification.

I took all my shit off for the blue slip and popped it all back on afterwards and Ive never had a problem, the police don't defect me.

You can get dodgy blue slips, just say you popped the stuff back on yourself, the mechanic won't get busted.

[2MPRSS]

yeh i know im doing that at the moment but like the engineer certificate i dont think mechanics would be stupid enough to give you one,even if they do its not gana be one u can use forever it would probably have a certain date like a rego it would probably expire lol

[XXpl0Sive]

Yep like I said

Engineers give you engineer certificates.

Yeah my car is the same :D

An engineers certificate covers you for the life of the modifcation on the car.. so if you get your exhaust tested, and its over the 95dB, and then get it engineered (theres only a list of about 25people in NSW/VIC/QLD i think?? you can download the list of signatories on the RTA website) your covered forever.. and whoever buys your car after you is also covered, so long as you dont change it.

I asked about engineers Cert. for wheels and its about $150, so i think about the couple hundered dollar mark is right. But still you wont get passed if your car is waaay outside the limits.

man my exhaust is like 3in from the cat back and it sounds much louder inside the car than out. Some of my friends tested their cars at TAFE (apprentice mechanics) and they were all about the 95-105 mark!


[[link for the PDF from the RTA.. these are the ONLY people who do it so i dont think they have room to be dodgy, its their lifes work. Most of them make mods to cars for handicaped drivers though.. Call around if your really worried Restricted Signatories (http://www.rta.nsw.gov.au/heavyvehicles/downloads/vsi/vsi02.pdf)]]
Take that back.. i found a list with a whole lot more engineering guys... Engineers Certificate Peeps (http://www.rta.nsw.gov.au/heavyvehicles/downloads/vsi/vsi15.pdf)

what have you got on your car dude? Its very rare for a car to be WAY over... or even near over. Unless your talking rotory only really Turbo cars are over... well thats been my expeirnce... and even if you think it is... Shove some steel wool in the tip and get it tested. or get a big muffler welded on temporaroly.

[geo41e]

talkin bout loud exhust...l'm getting an Apexi N1 muffler...are they like..real loud dudes??? just wanna know before i get it....and also...compare that to the Xforce muffler ??

[SIKCVC]

its a muffler, I doubt it would be that much louder... Its not like a full change in exhaust system

[2MPRSS]

i just wana put a nice chrome exhaust on my car that is loud but i just dont want no demerit points taken off meand soo my car is going bak to 8 cm off the ground right now its about 12 cm maybe more (it looks so yuck man uff)because of my iceboy body kit it looks more lowerd and 16z which i just put back on and thinking of geting 18's but ppl are telling me it wont fit on my car unless i get some panel job done to it otherwise its a no no,if i cant get 18's im going 4 17's and then a small air filter jst coming ou tof my right grill on my bonet (i had dreams about it it looks good :D) so yeh thats probably what im going to do to my car in the future and then leave it and sell it in about 2 yrs for around 6 or 7 thinking of geting a stock turbod car like r32

HAHAHAH ROFLMAO ... so true

[[[d a n n y]]]

loud hm..

96PB at 6000RPM is the limit

i got

107DB or sum shit like that

and comning down revs it went up to

137DB

[geo41e]

danm dude..hectic..what system u got?
full ?

somebody plzz tell me whats the Apexi N1 is likeeeeee
l have Genie headers..or extractors..and stock mid section.

[SIKCVC]

uuummm 8cm clearence is illegal dude... it has to be 10cm. If the guy who does your exhaust is any good he'll be able to tuck it up so the car could be legal... dunnow how low your kit is though... and you wouldn't need boddy work for 18s providing the offset is greater than +43 but you would need an engerneers since the largest size rim releaced in the EGs was the SiR which had 15s stock which means the biggest you can go is 17s.

I have heard talk of them introducing a loss of points system in NSW but I don't believe it has been implemented.

But as some have suggested, just be nice to the cop and you might get off lightly. In the past I have only ever been defected for having a non-standard exhaust system and not for being too loud, even though the cops said they could hear me coming from about 1km away and even then I was cruising on a flat in 5th doing 60kmh - all I had to do was get a pink slip. The cop stuck his head under my rear bar and told me to rev it (my exhaust was concealed behind the bar and fired towards the ground)...he scored himself the aural pleasure of a 4A-GE revving at 7,000rpm with a straight through exhaust - served him right!

Also it might be a good idea to drive resposibly if you know you have loud exhaust and want to avoid getting defected. Remember you can now get a fine/defect notice from rangers/epa/council, etc who see (or hear) you driving along...all they need is your number plate and you're gone.

And remember they don't need to test your system to defect you...all they need is their own discretion and it is then up to you to prove them wrong!

Sometimes though it's hard to be discrete when you have a 4inch tip N1 muffler hanging out the back of your car - if a nasty cop sees that you're gone - he doesn't even have to hear it....

I'm not sure where you guys are getting this figure of 95db from.
I called up EPA and the engineer, and both told me the limit is 90db, with normal cars producing close to 87db.

going from 90db to 91db is approx double the volume...so yeh

The instrument he uses to measure the 'volume' actually measures the change in air pressure.

[LatinoHatchCrap]

how about sourcing a quiet exhaust that still does the job and it passes emissions/pigs/epa :P

nah...man

i got my exhasut enginneered he said the limit is 96db

[XXpl0Sive]

that's weird, the engineer told you this?

[[[d a n n y]]]

yeap

he looked at the paper and it said
95.4

and he goes yeap all done mate..

[Mitch M]

my civic is far over 90DBs

probably around 96 ~ 98DBs ... a little higher when they back off in the EPA test

as far as i know no points are involved. Just a fine and the cost of fixing the defect ....

in fact i know for a fact, because a guy i know has 78 Defect notices for the one car ... its still on the road and he still has his licence

78 deftects??? why would u do nething to a car thats going to cost u 78 defects? every defect comes with a fine? correct me cos i dont know? I suppose if u have the money to pay for it ,who cares.

[XXpl0Sive]

to go up 1db is to double the volume..hope you know that

[SIKCVC]

96PB at 6000RPM is the limit

What about cars that dont achive 6000RPM????

The limit in victoria is 2 thirds max RPM(talking Redline) so on my car, 4300RPM and its 90dB. 90dB in ambiant air is LOUD. and considering its not even Max RPM theres more noise to come!

[Jus-10]

1db = double the volume???

The human ear can only physically hear the difference of around 3db increments...therefore, the human ear can't tell the difference between 90 and 91db...that's all I know anyway....

You won't always cop a fine with a defect. I have been defected probaly 5 or 6 times with various cars and have only received a fine on one occasion...on that particular occasion I didn't get the defect notice (just the fine). When I asked the cop about it, he said it was at their discretion as to whether the issue fines, defects, or both. He just said he wouldn't bother issuing a defect notice because it would get checked at rego time...little did he know that the car was only 18 months old so I didn't have to get it checked until after the third year....

In NSW as far as I am aware the limit is 90db, tested at 2/3s max revs. There is also a certain angle and distance from the tip that the device has to be (but I can't remember what they are) - sounds similar to Victoria.

The key to the testing is open air. They often test in places surrounded by factories where you are going to get a lot of resonance from the exhaust bouncing all over the place. Basically it has to be tested in a paddock or something for a true reading, but then I guess it just depends on how you interpret it...

Who the hell told you that???

[Jus-10]

Something I learnt from back in my car audio installing days doing testing and the like...

All I'm saying is that the human ear is unable to distinguish the difference between 90 and 91db, hence I do not believe 91db to be twice the volume of 90db, that is, unless I am simply misinterpreting what xxplosive is saying by 'volume'.

That's all.

[SIKCVC]

sound intensity basicly doubles every db.

[lane-o]

i got defected on my exhaust about 2 months ago. I got the notice telling me to get it fixed in 5 days, i didn't lose any points or money. I went and got it tested and @ 4000rpm mine read 92.5db. So i took my pinkslip and the sound test down to thr RTA and got it cleared. I should point out that i got defected cause i got pulled over for speedin....silly boy!
