I'm not sure if it was stated but were all those readings of C-weighting?
Also does anyone happen to know what the standard is for measuring noise levels as far as limits for causing ear damage etc... do they measure in A-weighting or C-weighting?

Because the db levels of these exhausts is mostly due to Very low frequency levels...possibly lower then the average human ear can detect. switching to A weighting drops the DB's of my greddy by almost 20db.
