There's a kit on the Jeg's website. It only works on carb'd cars without a cat, I hear you have to run it super rich, and I guess it cuts out the ignition for a second so all the unburned fuel goes through the exhaust and theres a spark plug in the tailpipe and a coil that fires it.

I think import guys use some sort of propane kit to add fuel after the cat. That would explain a different color also.

IMO, this should be reserved for '57 Bel Air's in flat black with flames that are so low they couldn't clear a sheet of paper.
