I also have the soot in the tailpipe. My 88 Ranger's (144K) just gets rusty not sooty.
Given that the soot is probably carbon and therefore a particulate pollutant as opposed to a gaseous pollutant, any smog testing equipment probably wouldn't care about it. It's my understanding the catalytic converter is essentially a furnace designed to burn off the NOx's produced by combustion in the engine. Maybe then it is the cat that is producing this black stuff. I'm no expert but I can't understand why one Ford product can have a tailpipe as clean as a baby's butt and a sister product has a tailpipe like a Mack truck. When I asked my dealer to rationalize what's in my tailpipe he looked at me like I was some kind of a nut. The truck runs OK for a V6 so I guess time wiil tell if the soot is a problem.
