lol - at a "Cruise" I had the pleasure of being the photographer for, there was a guy with one of these on his Escort.
Cue ragging the nutsack off a 1.6 escort with a drainpipe exhaust and a flamer kit.
I have to say though, the bangs from the flame were so loud and forceful that they were setting car alarms off behind it.
I'll try to dig out pics...
