hey guys i was just wandering wat is the legal limit in db for exaust noise. does it vary from state to state????? i was just wandering wat the number would be and how they would check it.

I think from memory it is 94db Also they use a db counter and get your car to rev at 3000rpm and take a reading from 1 metre away. You can get a certificate from an exhaust shop to say that it is under the legal limit.

In VIC its 90db, unsure what the NSW regulations are....Got done for 99db last week (standard manifold, standard cat, muffler in middle and hotdog at rear)...In VIC they rev the car to 4000rpm and use a testing device, but again the NSW rules may be different

im sure its 94 db in vic as well cause my mate had one on his vr calais 5ltr got 93db and the guy said it was just under

so wat appens if you are over??? is it a defect

hey mate, read my old post, hope it helps http://www.calaisturbo.com.au/showth...&highlight=epa (http://www.calaisturbo.com.au/showthread.php?t=30977&highlight=epa)

i went to epa as u do wen u have a vlt.. and i had 92 or something and they let me go.. they said it was supposed to be 90 but will let u go

hey thanks mr 30L that was helpful. how many fines can you get. far out that is crap. getting a fine for a loud alarm. Biggest bull$hit i have ever seen in my whole life. Do they want us to put our alarms on vibrate or something

its called owning a vlt.. u get done for anything

90 Db in Vic. I've been to epa before Some original photos have not been recovered yet.

the epa is my best friend lol

im positive its 90dB. but if ur a lil over ( 92dB ) theyll pass ya.

they useto rev it to like 3800rpm and now they can go upto 4200rpm. someone correct me if im wrong

I got mine tested at an exhaust place last week (as the EPA failed me) and they took it to 3900rpm and took the measurement....Depends where you go i suppose

10. Noise emissions from motor vehicles (1) In this regulation, "dB(A)" means the A-weighted sound pressure level expressed in decibels. (2) For the purposes of sections 48B and 48D(3A) of the Act, a passenger vehicle must not emit noise exceeding the following relevant level— Date of manufacture Noise Level [dB(A)] Before 1 November 1983 96 dB(A) On or After 1 November 1983 90 dB(A) From: Environment Protection (Vehicle Emissions) Regulations 2003 It varies on how many revs when tested depending on what sort of vehicle is being tested. It is all in the Act if you're really really really bored.

mm annoying they bust cars like VLs with a 3" that if anything are a bit droney.. yet a harley flies past on full noise and it's quite ok coz they come from the factory loud.. I dont think my ears or environment distinguish or care what year a car or bike was produced.. Vls aren't loud cars.. even when worked (except you screamer pipe boys lol)..

I highly doubt that an exhaust shop would pass a 92 dB reading. For every 2dB the noise doubles. eg: 92dB is actually double what 90dB is. They wouldnt risk losing their license for that. They rev your car to 3/4 of maximum power. eg: my 5 litre got done at 3000rpm... they check in the book for engine capacity etc as to how hard to rev it.
