Disable censorship in certain forums

To clarify, I want the censorship to be in effect for all forums except 2. The 2 additional forums are only viewable to a certain group.  For these 2 forums I want to find where in parser.php or functions.php (or whereever needed) that I can put an if statement to see if it's forum 25 or 26 then don't do the censorship function.  I've tried all the places I thought, but none of my changes worked.
