that was the gayest thing I've seen in a long time. its one thing to backfire when shifting etc while driving due to rich mixture and no cat...but to make the car into a rapid fire flame thrower, thats just rice

maybe theres a little Rice in me... I like blue lights(blue is my fav color) stuff that Glows in the dark, Polished things, Loud exhausts, and FIIIIIIIIIIIIIIIRE!!!! Flame paint jobs suck, who needs'em when you got REAL fire.

Flames out the tailpipe/header are a result of timing, and happens as a result of the "Duration" of the lobes of the cam and the "Overlap" of the intake and exhaust valve.
When piston comes to top dead center the spark fires and for a brief moment the intake and exhaust valve are open that is "Overlap." This creates a vacuum that draws air in to the intake, but under deceleration flames shoot through the exhaust system. If you have ever listened to a High compression race motor it Lopes at idle almost as if it wants to die but can't. The sucking looping sound is the overlapping cam and frigg'n huge Intake and exhaust ports sucking air. Now if you bump the throttle cam the RPMS will rise sharpe, but upon deceleration flames will exit the headers. The flames are a result of unburnt fuel, air, vacuum, and the exhaust valve being open when the spark fires.
However, if a cam has that much "Overlap" there is a distinct possibility that at idle it will not pass emissions inspection.
Now if you’re Pimp-o-riffic, and want the flame effect. I think there is a spark plug system you can install in the tail pipe.
