(kill your engines ignition and put a spark in the tail pipe, the problem is this is harmfull to your motor)
not bad for the motor... as long as everything is still getting oil then its fine, and it is, becaues the motor is still turning over.

you won't kick flames with a catayltic converter, it will burn up all the unused fuel and make that horrible sulfur smell... thats why they are there, to complete combustion and convert carbon monoxide into carbon dioxide. carbon monoxide is a biproduct of incomplete fossil fuel combustion.
most turbo motors kick flame when you lift because the bypass valve dumps off the boost, but the fuel is already atomized and in the intake manifold so it runs rich for an instant, giving that flame... the more horsepower the more fuel its dishing out, so the bigger the flame.
porsche 962's kick a very good sized flame, coming all up in the diffuser and wing... it looks pretty bad a s s from behind.
about the helmets, he's right i was lookin online the other day at more $$ closed face stuf, but i noticed you can pick up an open face snell 2000 certified for ~ 150 and sometimes even less.
i've narrowed my search down to the beiffe f1-gpv or the arai gp-5, i already have a arai gp-3... i'll probably wait until snell 05 comes out and get a new helmet then.
