    Something I can comment on!

    When I built my Triumph chopper it had to go to Regency, the testing station here in Adelaide, they wanted to see the lights and indicators working and as it didnt have a battery , only a magneto, I had to start it.

    I kicked it over and the inspector said it was too loud.
    He pulled out a microphone and put it on a tripod near the exhaust, he even measured the distance with a tape from the end of the exhaust.

    He told me to rev it to 2500 rpm I just reved it off idle and said I didnt have a tacho.
    He went and got a muliti meter looking device and held it near my leads and it showed the revs and had me take it to 2500
    I was 2 db under at 98 as my bike was allowed 100 as it was pre 1990 or something like that.

    He said as mine was pre whatever,  the exhaust didnt need Aus standard stamping but if it was after the date he said( I cant remember) he said it would fail if it didnt have the stamp even if it was below the allowed db.

    Now that you've mentioned it Scouser I do remember hooking a mulitimeter up to a coil (cage) years ago.  I think that was a specialty meter though, with an RPM setting and all kinds of auto goodies.  Wouldn't be surprised to hear road side testing would have one.  That answers my question as to how they'd do it.

    So I'd take from that board in the original post that my Breakout is good to 100db, 95 as per the compliance decal +5db, that's probably not too bad if I'm correct.

     I think you've interpreted that incorrectly.  After ADRs were enacted, you have a limit of 94 db.  If oem exhaust is less than the limit, you can only add a small amount of additional noise.

     Maybe but that's the argument I'd be having a crack with, my Breakout is definitely stickered at 95db so it's already factory "illegal" if 94db is the top.

    In reality if you stay away from the known hot spots in your area (i.e. Mt Glorious in Brisbane on weekends) and don't ride around everywhere like an arsehole, wear "colours" or "Sons of Anarchy" T-shirts (in some states), you probably don't have to worry too much about getting hassled by cops.

     Hi, why would a bike not have a sticker on the swing arm? I have seen a few bike lately that don’t have them and the are Aus HD’s. I have also seen pipes with it engraved on the pipe but no sicker.... swap pipes  you are stuffed. Or maybe it is under the seat???

    So how would one get another sticker, put the stock pipes back on get a new test and be issued with another sticker?

    My sticker cam off because I power washed the mud from the rear wheel.  I had to order one from the dealer (HD) and it took weeks to arrive - can't remember what it cost but I remember thinking it was a fucking idiotic that I need a stupid sticker.  YMMV

    This is for S.A
    Look up noise it allows 94db with no mention at all of +5db?

    Years ago I had a Cagiva Mito 125, little 2 stroke single.. thing was not far off a 125 GP bike with headlights.
    I got pinged for noise (redlined it past a cop car), when I went for testing it failed, stock factory exhaust... it had no baffles, was straight through and loud as fck.

    Problem came up, ADR testing has something to do with displacement X power = dB at xyz revlimit.
    Meant a little 125 was tested at 4000rpm. These bikes idled at 2000rpm, powervalve opened at 8000 and redlined at 11000.
    It was fckn loud, ear splitting loud at 8000.

    So regardless of it being the factory exhaust, unmodified and passing adr, it wasn’t complying with local testing, was a nightmare that saw me sell the thing on as someone else’s problem.
    Goes to show how stupid the state vs federal systems were.

    NSW, if you fitted aftermarket system, seller had a sticker to say system met the noise test. if you had that on your muff to show cops, got past if pulled up. but think law has changed.
    I have only ever been defected for noise once, & was on my old Shovel, all the info cop gave me turned out wrong. wrong phone # for EPA. but got in touch with EPA they told me shovel could be over 100db as older. went to muffler place had a test, got a form from them went to rego. guy there took defect off said, the cops don't know & waste there time so carry the form he filled out, to show any cop that stops me in future. has never happened since. but I've never liked the look of these new pipes, a lot fit, can understand why people use them, but I've never needed too. QLD Cops from what I've seen throw a curved ball, or it might be the state government . but last year I road top to bottom or QLD not one problem saw less cops than I see patrolling in NSW. but I'll give FNQ bikers the thumbs up, ( they still know how to nod or wave to another biker on the road. sad to say NSW don't.

    Is there an accurate affordable db meter out there? Be interesting to play around with

     I downloaded an app for my phone/tablet.......there are plenty of free ones.

    If you got a iPhone there are a few descent apps to download which will give you a idea of what noise your putting out. Mine will fail either way V&H big rads mixed in with a stage 3

    Sorry OZdan I didn't get to reading your earlier post mate

    I purchased a Db meter and laser thermometer off eBay. About $40 each. 
    Db readings on my iPhone App are comparable but as the mic doesn’t have any wind protection like the Db meter, (foam ball) it’s only useful in the garage on maybe on a very still day.

    There's loud and obnoxious and then there's that sweet rumble.  I don't care if they take all the obnoxious pipes off the road but FFS don't go down the path or V8s went where half of them sound like bees farting.

    Hi gents,

    Been testing a few of those free apps for testing my exhaust.

    Calibrated them as advised then checked the bikes note.

    With a set of Freedom 4" Racing pipes with no quiet baffle inserted the results were.

    Idle 1000 rpm 86 Db.

    2500 rpm 86 Db.

    4000 rpm 86 Db.

    One of my farts coz I couldn't resist testing it 82 Db. LOL

    Cheers

    Hi Hilly,

    the apps said that they go to 120 Db. but that maybe wishful thinking as well.

    I tried three different types and all gave the same result.

    There was a mention about the capabilities of the built in microphone on the phone. That may have some bearing on the levels as well.

    Jaycar sell one for $50 with is rated from 40 to 130 Db.

    cheers
