I dont plan on doing this but im curious, can someone explain to me what they did to their cars to make it do this....it looks too natural to be something like a flamethrower kit....

i'm no expert, and i'm watching this video with no audio, but i'd say it is a flamethrower kit

repost x's 50 lol i dont know how they do it. my friends mazdaspeed protege doesnt have a cat and sometimes itll belch blue flames out the exhaust

i know some cars that have full exhaust with no cat get a spark but thought there has to be more done, also many people dont tell you all the mods they have

yea, thats what i thought too....just straight through pipes with no cat and a rich running engine or something.....

it has to do with high volume fuel injectors with mainly turbo setups and no cat...the cat is what filters the rest of the hydrocabons (unburnt gas) out but if there is no cat and usually turbo cars with high volume injectors when the let off the gas it burns rich cuz the air is cut off from the throttle but the fuel has already been injected so the unburnt fuel comes out through the turbo which if hot enough can ignite the vaporized fuel (and not just the turbo) than if the catylitic converter is not present to filter it out it comes shooting out the muffler in a puff...but since there was very little oxygen in the turbo and when the excess fuel exits the engine and hits the oxygen right outside the muffler its hot enough to combust which produced your backfire during deceleration when air is cut off...

misfiring systems are different from those

my friend's turbo 6thgen doesnt do this and he is running hella rich w/o a catalic converter

that most likley means the engine is not running efficiently enough
