I didn't read the entire article, but did read where it said the allowable db level is 80.
But according to the AMA, for NY......
First off , you can't pick a specific db level unless you provide specific data on exactly where and how a meter is to be placed...not to mention the placement of the bike itself.
The AMA specs are for a moving vehicle, on the road, and are to be taken when the bike passes a point X feet from the meter. The concept of the police using a decibil meter on a parked bike without any way to measure the distance of the meter from the bikes exhaust, is rather silly. Numbers here would be meaningless. This was argued over in Colorado a few years back and the upshot was not to rely on officers training , or lack there of, on using a decibil meter, but to simply issue tickets for "non stock" exhausts that "seem to be louder" than normal. Still kinda sketchy though....lol.
As many of you know, I personally hate loud pipes. However, the idea of "checkpoints" that single out all bikers to check their pipes, regardless if they show signs of being illeagal, borders on fascism.
And yes, you can gut your stock pipes so they are really loud, but still display the EPA stamp. So really not sure what the best criteria would be for law enforcement to use to make that judgement.
I do know that one can tell from just being in proximity of a bike whether it is too loud or not, but to make a law that one can enforce you can not go by "opinion", so not sure what to do other than train officers to know what to look for in altered exhausts, and establish a user friendly guide for use of a sound meter.
So, more than likely, some unfair , but usable criteria will be developed , and will be slowly taken in by state to state, making it impossible for any rider to alter his exhaust, buy an aftermarket one that does not carry an EPA approved stamp, and create a pure custom bike exhaust without spending loads of $$$$ to get it "approved".
AND you all have no one to blame it on but all those azzholes with excessively loud pipes. I told you so.
