I know nothing about midpipes so please forgive the ignorant questions - do you have a switch to turn that on and off? It would be embarrassing if that *always* happened at 3,000rpm and a cop pulled up behind you at a stoplight.
What does actually trigger your flames?

It must be a function of the muffler you use to control what the flames look like. Your flames look like giant puff *****, whereas mine with a corksport exhaust look like jet flames you'd get from a torpedo heater. While I have video, I don't have any good pictures like your.
Just FYI - flames can easily appear with the replacement of the exhaust system. A high flow cat or midpipe and a good muffler. Just allowing more freeflow.

Seems like a cool effect if you can do it on-demand, but I can't imagine that you guys drive around with flames following you all the time. Heck, if police will pull over folks with legal under-glow kits just imagine the coniption fit they would throw over blowing flames on the car behind you as you pull away from a light.
Is it only an occasional burst due to a build-up of certain conditions in the exhaust system? Seems like it would be hard to photograph in that case.

I seem to remember being able to do this stock (or maybe just a cat back installed). You need to stay in a particular gear for your speed and run at high RPM for an extended period of time. I think a WOT shortly after will shoot the flames. Our exhaust fumes run much hotter than conventional cars.
Here's a thread dedicated to just that

Thanks for the link snizzle. Jaisin, the flames in the video on the linked thread ( http://videos.streetfire.net/Player....5-B772A10C6C4E )* are not nearly as nice as the picture you posted. I'm not sure "flames" is the right word for that video - to my eye they're only "flashes". Not as dramatic as the solid flaming ball Jaisin shows.
No offense intended to Diabolical RX8, but those flashes just aren't exciting enough to me to justify the abuse on the car.
Maybe what I'm thinking of are some really sick mods from some TV show on the Speed channel where they actually dumped raw fuel directly into the tail end of the exhaust system and created sustained jets of flame. I remember one brief scene in "Gone in 60 Seconds" where a street rod did that - long jets like twin flame-throwers.

You should just need a midpipe to do this. Without the cat the extra fuel at high rpms escapes into the muffler. Because the rotary runs hot the exhaust is hot enough to ignite the fuel in it. This usually results in a fireball. To do it you should run up to 7 or 8k in second gear and let off abruptly. It can also happen when shifting at redline. Nothing you should be doing around cops. Rx7s also do this. There are some great pics and vids on the other forum of this. Its just something that the rotary does.

the key ingredient is the midpipe, no silly cats to catch all the unburnt fuel!
btw for those that don't know already, the midpipe REPLACES the whole catalytic converter system with basically a straight pipe (sometimes with a resonator to reduce exhaust sound), which means in states where emission controls are regulated, it is ILLEGAL!
