You will get different numbers with the same bike in different locations and atmospheric condition when using expensive equipment and highly trained technicians.
What really matters is what number shows up on the cheap sound meter with a highly UNTRAINED park ranger.
What the park ranger sees on his meter even when he may have the meter on the wrong scale determines if you get to ride in his park.   

i guess im not the only one who thinks they are, along with CHP hahaha

This reminds me of that sticker from the 90s. "Loud Pipes Save Lives."

i still hear Harley riders quoting those stickers to this day, i guess it makes those slow machines feel "fast."
