Yeah this was disscussed thru SEMA...I kept an eye on this but was pissed when they passed it...Oh well I guess you gotta start learning to press the clutch in while going by the police... 
No its not a bad law. I thought I would share it would everyone. What do you have for a Nissan? I work t Port City Nissan.jlpearl said:This is not a bad law guys. Before it was completely arbitrary, and ALL non-stock exhausts were illegal. If it was any louder than stock yould get a ticker. Trust me...3 tickets later I think this new law is great. At least I know what to shoot for, and can stilll build a 3" exhaust.
I have an update to this, seeing as I was the one that passed this on to you.Mikeyb said:NH just passed a law (HB243) that requires testing of the exhaust to receive a ticket. Basically, it must be louder than 95 db, using an SAE-defined test (something like 20" away, 45 degrees down, at 75% rpm of full power).
HB243 ==>> RSA 266:59, III, relative to modification of motor vehicle
exhaust system, is repealed. That section has to do with modifying the exhaust to be louder than stock.
This has been passed by the House, and is being reviewed by the
Transportation committee (Senate), and it is expected to pass OK. When it
does pass, it will be retroactive to Jan 1, 2004, so anyone who has
received a ticket since then will be able to go back and fight it.
I thought I would let you all New Hampshire members know.
