ROLLING COAL

[tx2sturgis]

Here is a random video I found where a shop removes all the emissions crap from a Dodge Diesel pickup and the truck will perform much better without it. 

Better fuel mileage, more power. And just as important, it will be more reliable, well, at least the engine will be. Sometimes the transmission is not able to handle the extra torque and that might be an issue later on. 

In this video, they do pay some attention to smoke output at normal highway cruise, but I can just about guarantee that the owner will rotate that aftermarket HP selector knob poking out from the dash to MAX especially if he ever pulls a trailer or is passing someone up a steep grade and that truck will be ROLLING COAL!!!
