As a hypothetical, and ignoring the resultant loss of power, what's the absolute quietest an '02 wr450 can get (in decibels)? Combination of inserts on the stock exhaust?

You mean 426?

The quietest you can get it is probably in the mid 80 db range. My '07 was 88 db @ 4500 rpm with the stock pipe/stock baffle and in terms of flow thats a bad as it gets.
