Exhaust pops and bangs

This can be done by ECU manipulation. Popping in general can be produced by let the engine run a little bit rich fat for a short time while you go from the gas pedal. But this has to be done by someone who is knowing what he is doing, because that can also ruin your catalysators.

Program right, and with enough heat you'll get a nice little fireball, ala 930.

I worked with some Formula Mazda`s. They can shoot flames. First thing I was warned about.

We are yes, and both of us are in his new autobiography. Which is a little weird, lol.

I may have to look into this! Is it a known thing to do this?
