Cummins Stage 5

Now on stage stage 5 cummins engine they removed EGR and all we have is one canister for after treatment and thus they said we have more power and more torque. This is great because these engines are again simple and no more complexity, back to basics. Even sometimes they are using again wastegate capsule and no more VGT. I wanted to know if we can use this new design on the stage 4 engine and thus reducing complexity and benefit from the increase in power and torque, in other word reducing fuel consumption and being environment friendly .
