Anybody make a homemade exhaust flame thrower?

I know this has nothing to do with what you're trying to do but... I had a 71 Roadrunner, 340 automatic. I put headers and glass packs on it. Then pipes on a 45 came out ahead of the back tires. I'd be coming down a hill and downshift. It would shoot a 3 foot flame out the exhausts. Sorry, this was in the 70's so I don't have a cell phone video.
