Exhaust flame throwers

flamethrower

Here’s a hack that’s been around since the very start of the hot rod movement. Car exhaust flame throwers work by interrupting the spark to the engine. This dumps raw fuel into the exhaust system. The fuel is ignited by a coil and spark plug placed right before the exhaust tip. Doing this will shorten the life of your engine (and pedestrians). The raw fuel strips the oil off the cylinder walls and contaminates the oil causing more wear and tear. Also, this mod can’t be used on a fuel injected car. It would foul the O2 sensors and catalytic converter. Never the less, our fascination with electricity will live on.
