Black exhaust smoke means the engine is burning too much fuel. The first think you should check is your air-filter and other intake components like the fuel injectors and the fuel pressure regulator.
Black smoke usually means the engine is running too rich. The fuel/air mixture is incorrect. Blue smoke is oil burning.
how can i get black exhaust smoke stuck on my dual exhaust
Need to know why this is necessary.

Assuming this is a gasoline engine, it is running rich from excess gasoline.
If its smoking under the hood, you may have an exhaust leak. Get it checked out ASAP. If its smoking excessively from the tailpipe, white smoke means youre burning oil, black smoke means youre burning too much fuel (mixture is too rich)... Also get it checked out.
possibly needs a new carborator
black smoke means your burning oil and the head gasket will go sometime soon
