Oh, I hear you. It is EASILY done and at least in the 2007-2009 products, it makes them run much nicer - but much much dirtier. I do not agree with removing modern aftertreatment systems, even though economics often dictates otherwise. I believe they are a necessity and once the growing pains are mostly over, nobody will notice them anymore. I would say that 50% of my job is dealing with aftertreatment issues, but I can see that they are slowly improving.
To throw a wrench in the discussion, I found a biodiesel vs diesel emissions chart. It kind of goes against what I thought about biodiesel:
