i deffinately don't want to single anybody out, but i think that before you do a post you should probly do a seach first. this has to be atleast the 10th question in the past couple of days related to stock decibals or after decibals. just a heads up. and i may be guilty of this too, but i don't start that many posts i mainly reply to them.

when mine was stock it was 88db I've seen a site that took comparisons on several 400ex some were louder than others and they ranged from 88db to 92db white brothers E series is 92db with quiet core and 95db without

Yeah the stock pipe is 88db.
