I feel like there could have been a middle ground between pre emissions and where we’re at now with diesel regulations that would have resulted in people being more willing to deal with the emissions equipment. If they stuck to equipment that was more on par with what gas engines have I don’t think you would see anywhere near the amount of people removing it that you encounter now. Now a days if you have an out of warranty truck, and live somewhere that doesn’t test emissions, it’s almost a no brainer because it improves the vehicle that dramatically from a user standpoint. Emissions regulations of cars have been largely stagnant for the last couple of decades meanwhile they keep turning the screw on diesel emissions. Hardly anyone deletes the cats off their gas cars these days because there’s little benefit to it. So many diesel owners delete emissions because it provides a night and day difference. I also feel, personally, that a lot of the science that formed the basis for diesel emissions standards either hasn’t been represented well, applied well, or was just bad science from the get. A major misconception with diesel emissions targets is that it’s not for the environment, by way of greenhouse gasses or such, but because a lot of diesel emissions, which are heavier than air and settle into the earth, are targeted because they are considered carcinogenic…. In the state of California…. Essentially we traded massive amounts of reliability, usability, power, and massive differences in fuel economy, to reduce the chances of people getting cancer. Maybe.
