What makes a car exhaust pop and backfire?

Most rally cars have that pop sound coming from the exhaust when the rally driver lets go of the acceleration or changes the gears.The pop sound and backfire happens because the car is over fueling and the left over fuel that is left in the exhaust gets burned off which then causes flames to shoot out of the exhausts tail pipe and makes your car to pop so loud! Over popping is bad for your car exhaust because the heat from over fueling left in the exhaust system can reach up to 300 degree's and can cause your exhaust to catch on fire or melt the catalytic converted.
