The question is " how do I make it blow black smoke out of the exhaust? like burning oil or something." First of all I liked the answers so far. Imagine what it would look like with a lot of burning out of the exhaust, boy will he be thinking ------------. all the people thinking that ----------------.

It's unburned diesel fuel. You would do it by flooring the pedal, which wastes fuel and stinks. Grow up.

I only do it if someone is tailgating me. 5.9 Cummins owner.

"Rolling Coal," is proof positive that you want to make up for the deficiency that is between your legs.

Redneck entertainment. Because there's already not enough idiots driving diesel trucks.

I'm getting a 3500 pickup truck that uses diesel. I'm planning on getting stacks on it, how do I make it blow black smoke out of the exhaust? I would love to have it do that, it looks cool. Not In a bad way though, like burning oil or something
