Sound levels
I recently did the stage 1 mod's to my '05 1200R using the Hurricane AC and SE II Pro slip on mufflers. I really liked the sound and even the wife said it wasn't obnoxious but I was curious just how loud it was. I borrowed our sound meter from work and checked it out. I didn't check the bike before doing the stage 1 so I don't have anything to compare it to, but here's the numbers, all measured on the A scale:
Standing next to bike
At idle 83-84 dB's
2000 rpm, no load 92 dB's
For comparison:
2002 Dodge Cummins Diesel
At idle, standing next to front wheels 76 dB's
Jinma 22hp, 3 cylinder diesel tractor, standing next to front wheel
At idle 72 dB's
1500 rpm in operators seat 83-85 dB's

So... in other words, about 16 times the EPA's 80dBA limit!

Which if pulled over in Oregon would get you a ticket.

The cycle shack slip-ons slash cut i had on my 2004 1200r
were 101-103 db at 2500rpms ,at idle they were 91-92 db.
at 6000 rpm they were 118 decibels of SWEET HARLEY THUNDER!!!!!!!!!!!!!
much louder than screaming eagle ll's.
i still have the pipes for sale in classified section.

sound levels
Like I said, I never check the noise level before I changed the mufflers. I'm sure the stockers met the federal limits which I think is 80 dB's max.

I meant the level before you started the bike...  |

Distance from the bike makes all of these measured levels a moot point. A measured sound level will fall off exponentially (power of 2) with distance (should be a 3dB drop every time you double the distance). I don't know what the distance is spec'd by the EPA, but here in NY the law gives dB ratings for a meter which has to be 50 feet away from the center line of the lane the bike is riding in.
