Flames are easy to achieve, on almost any car! No need to go to all that work...
Just install another spark plug near the end of the tail pipe, and wire it to any one of the normal spark plug wires. Be sure to install a push button (you probably don't want it on ALL the time) and a suitable relay inline for on/off purposes.
Then crank it wide open and order up some fire!
Just think, it's environmentally conscious by burning off those last remnants of unused gas.
Oh, best carry a fire extinguisher too...
