i think you can get a kit for it.... not exactly sure how it works though, but i think it ignites the excess fuel in the exhaust when the throttle closes or something along those lines...
On the special features on 2 Fast 2 Furious DVD. The tell you that they use a Reactive Exhaust to create the flames. Hope this helps. Cause it looks cool as hell
thread a socket into your exhaust and screw in a low powered spark plug and hook it up to your car battery (with a switch).
people use to do it 20 years ago - nothing new. probably got a better way of doing it now.
Cause your throttle is still open & have a chance that the flame might travel back, & i'm sure u know what happen next!!!!! & 20 yrs ago there aren't any EFI so, these days if u want 2 do it, at least do the proper way, use a computer chip 2 close the throttle first!!!!

obviously you missed the part of the which had "with switch".
2nd chance of going backwards are minimal anyway. Need oxygen to burn which is why it happens exiting an exhaust, else anyone who would try it would have toasted anyway. These days there isnt as much fuel traveling down the exhaust as in the carby era.
