I've heard that you can make flames shoot out of your exhaust pipe in your car by drilling a hole and putting a spark plug a few inches from the end. Then, by connecting it to the battery and a switch, you could make a sort of flamethrower. I would just like to know if this is a buncha baloney or not, without having to actually go out and ruin an exhaust to find out.
It is dangerous, the kit that is. The do not hold any responsibility to the use of it. I have heard stories where it set the car on fire becasue the flame burnt the fumes that were in the exhaust system also.
