I would have much rather the Urea/SCR thing would have been done first instead of the EGR [censored]. I don't care for any of this stuff, but having all emissions stuff handled outside the engine is a far better way to do it than making an engine eat it's own feces. As a side note, it has been shone that they can reduce EGR because of the SCR, and this in turn allows the engine to be more efficient and in turn the DPF doesn't have to do regens as frequently. Now, if they could just do away with the EGR, things might be more tolerable.
