Anytime moment you notice fire on an exhaust pipe, just know that unburnt fuel was let loose into the exhaust system which ends up catching fire.
If you want to see your car throwing flames through the exhaust pipe, it is very simple, get rid of the catalysts responsible for cleaning the fuel from exiting your car unburnt.
This idea is awesome for bad and fiery guys but lethal for environmentalists!
You are definitely done, go behind the wheel, accelerate so fast, play with the throttle so that their is much fuel released to the hot pipes, the result is a flaming car for bad guys!
There are no clear rules guiding usage of flaming cars and vehicles in Kenya, but no doubt such a car or vehicle would be a disaster in a filling station
Below are a list of Kenyan cars which have attempted this trick and achieved it easily.
