    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

    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

    Haha an 82 dB fart.....

    Mines loud, but I’m new to HD and so I like it (it can be a bit much on a longer ride though). Then again, I like the old Cat C15’s in trucks coz they’re loud too, and I’m not that new to that :-)
    I’d never thought to download an app, cheers fellas. 
    I just checked and yeah, it’s a bit over the limit. If I end up changing pipes, I think I’ll go with those D&D Bobcat pipes that Hot n Heavy has on his.

    I  might have to check my sticker, I did not think yours were loud Gnoo. But I'm a nice guy.

    The qld testing is not legal as it’s done outside and prone to outside noises interfering with the testing and it doesn’t comply with the Aussie standards, there is a lawyer up there doing a class action or something along those lines as he says no way they can meet the standards testing outside with background noise.

    LOL, no pipes inserted. Straight from the exhaust port.

    Mind you there was a particular good Vindaloo involved from the previous night, that may have helped as well.

    I grew up when v8s were the norm and the gurgling of a finely tuned (or not so finely tuned) was something even the older generation admired.  Seems to me we're doing that lazy policing thing again where it's just easier to grab everyone who isn't "in the box" rather than hitting the streets and grabbing the guys who are running obviously obnoxious gear.

    So since we're all destined to become pussies are there any pipes that give the rumble without the dbs when the revs go up?

    Bonkerz back in 70's, I was driving my tuned v8 ute through Parramatta ( Sydney's Wild West ). Cop jumps out in front of me, ordering me to pull over, say's that sounds good! now I'm going to book you for noise. I had a mate who was an engineer with me. he told the cop it was within the limits & had offset mufflers. so was ok. so cop could not argue as was not an engineer.
    just saying it was around then too.

    Unless they were REAAAAAAAAAAAAAAAAAALLY loud I'm amazed.  Throughout my youth I only new of one guy who ever got stopped (he got off with a warning in the end) and his "rumble" probably smashed windows as he went by  :P

    Yip! And I’m afraid that that the whole “pecking order in society” has changed! Suddenly certain members of our government are no longer considered as “Civil Servants”, and with the powers these certain members now have, “joe blow” in the street is suddenly guilty until proved otherwise! 

    On the other hand I don’t think that any of us oldies would argue that times have really changed in terms of society norms and parenting, and a whole lot of fucken other things too, and, thus the younger generations have changed along with that, and I guess it’s us oldies that are now trying to eradicate things from society that have become or shortly will become, accepted by society, based on the moral standards and the prevalent “society norms” at the time of our upbringing.

    On the other hand, it’s costs a lot of bucks to prove yourself innocent, or a failing in the system!

    In short, WE can’t make EVERYBODY happy ALL the time!

    It’s the so called “man in the street” that is now, today, potentially soo much more.......suicide bomber, terrorist, bomb maker, drug dealer....etc..than just the “joe blow” you walked past in the street, or shared the train carriage with in yesteryear. 

    Jesuuus, we all hate the bloody rigmaroll (spell) just to get on a plane, but......thank goodness, at the end, that we had all the rigmaroll because we got where we needed to be in one piece, mostly, except for the guys sitting in economy, lol..

    That’s my rant for the night!
