Just got my bike tested for noise by the local law. I,ve got an 05 ultra with a 103 motor and V&H slipons, also a P.C.111 fuel management. They had me run my bike up to 2700 r.p.m. It checked out at 92 decibels. The law says 91 decibels max. He said I would have no problems as their bikes are the same as mine. Good to know. At least gives you all an idea of what 92 decibels are.
