Black smoke

[ABV]

I have a truck, and I want to put exhaust stacks on it like a semi. But that would only make sense if it blows out black smoke like a diesel. And if it blows out black smoke like a diesel, how can I make the engine sound like a diesel too? I heard you can stick a mixture of sand and lemon juice in the oil to get the sound, but will that help make black smoke? Also, how do I open the door with exhaust stacks in the way? Can I get lambo doors? Will the exhaust still be hot when I get out? Can I make an ejection seat without a sunroof? What does my passenger do? Has your head exploded yet?

thx
