He's back!

Holy crap did anyone watch that thing the whole way through? At the end, it shows the back of his car, and the exhaust pipes look like the exhaust wake of a jet engine. He's got a steady foot-long conical flame coming out each pipe. I don't know much about the workings of engines, but that flame would have to be at least a steady 15 feet long to do that. I've seen a lot of race cars that will bark a flame out when they're hitting downshifts, but nothing like this. How does that happen?
