hey recently i found out my car shoots fireballs out of its exhaust is that a good or a bad thing

 

It's a "normal" thing. The RX-7s run rich, and have a very hot exhaust. Afterburn outside the tailpipe is normal if emissions control is removed (and even if it's not removed, sometimes).

FYI, they happen when the car runs rich. The gas is hence rich in the ehxaust, where it is *VERY* hot. To the tone of 1600 degrees or more depending on how you're driving. The gas can't combust in the exhaust because of lack of oxygen. The second that very hot gas meets the cooler oxygen outside the exit of the ehxuast, it instantlhy combusts, causing said fireballs.

 

call it the "anti-tailgating-ricer" exhaust.

 

Only problem is that it leaves soot all over your back bumper, and it may happen while passing a police cruiser, which is always bad news!!!

 

THAT'S TRUE cops suck.....say it's a leaky injector and pretend ur worried.

 

i was pulled over for flames before and the cop was reel cool about it he had a rx-7 when he was younger so he knew about it and asked me to do it again. i dont get soot over my bumper but it turns like **** yellow i gota clean off once a month.
