4/22/2012 Ambient sound(high 40s) and My voice (65db). Then test with Motor warm. Idle @ about 700rpm 10' to the side(57db). 2' Directly in front of the pipe(67db)

Test at 10 feet, directly to one side of the muffler. I used max save setting to catch the peek level. I tested @ 3000 RPM. This is higher then needed to go 55mph in 4th gear.

Culpeper does not even have a sound ordinance. The last one proposed, over 2 years ago, stated that sound levels had to be above 80 db for over 15 minutes before one was in violation.

Edit: the rain will not let up now. Will test more when I get the chance.
