Why do souped up cars backfire?

What happens when exhaust backfires?

A backfire is caused by a combustion or explosion that occurs when unburnt fuel in the exhaust system is ignited, even if there is no flame in the exhaust pipe itself. Sometimes a flame can be seen when a car backfires, but mostly you will only hear a loud popping noise, followed by loss of power and forward motion.

What causes a car to pop and bang? “Pops and bangs” are created by unburned fuel in the exhaust system. When excess fuel enters the exhaust system it increases in temperature and ignites inside the exhaust instead of the combustion chamber. The noise can be exaggerated by fitting a decat or full decat exhaust system.

Does shooting flames hurt your car?

The first piece to wear out is that exhaust valve, which can get burned with excessive fire-spitting. If those valves can’t close when fuel is ignited in the chamber, it leads to a lack of engine compression. The car’s performance will drastically dip, and the engine itself won’t operate properly.
