I see your point (not that I nessesarily agree with it), but Diesel smoke is actually soot and doesnt get trapped in the atmosphere.tofuman wrote:i dont have to worry about emmisions, i live in indiana, and the way i see it, if semi trucks can blow out huge plumes of black smoke then a back fire or two from my 2.4 gas saver is no big deal. if i lived somewhere where they made me pass emissions tests , i would tell them to shove it up their arse!!! thats just one more way on the man controlling ur life.
