I live in Maine and they have already done that. A LEO can give you a summons for Loud Exhaust based soley on his hearing.
You then have the right to challenge it by going to and approved Inspection Station and having the SAE J2825 Test performed.
However, No Inspection Station is certified to do the test and none want to spend the money for the test equipment. So I have no recourse.
At least you have certified inspection stations setup to do the test. All they have to do is use At Speed = 2000 vs At Speed = 2800.
How to Perform a SAE J2825 Motorcycle Sound Test and HD it is Idle = 92 DBs and At Speed, 2000 = 96 DBs.
I believe at the moment NH is At Speed 2800 = 106 DBs?
I am not saying I am in favor of it or not. IMHO, if the few continue to go their own way, All of Us will suffer from it.
Seacoast gave my neighbor and i a free test.
My 03 SERK with SE Touring was 91 DBs at speed and Mike.s 09 RK with supertrapps was 92 DBs at speed.
The only aftermarket I have seen addressing this so far has been supertrapp, they offer 9 exhausts that are SAE J2825.
