A few days ago I asked for comments regarding adding an Aeroturbine to a Banks Monster Exhaust. Nobody really addressed my question. And no one answered that had used the Aeroturbine/Monster Exhaust combination. Could it be possible that no one has used this combination? In which case, that would answer my question. The question basically is: What, if anything, do I gain by adding an aeroturbine to a Banks Monster Exhaust System on my 99? By gain, I don't mean a "cool" sound. I'm looking for lower egt's more MPG's and promoting engine life.
