The Autoloc Flame Thrower clips onto your tail pipe and sparks fuel that should have been ignited and consumed in your engine, sending flames up to 20 feet behind your car. (In my experience, you’ll be lucky to get more than a couple of feet of flame, but it’s still impressive.)
They’re “designed for carbureted vehicles, but can be used on fuel injected vehicles with additional modifications and parts.” What they mean is most modern cars aren’t coughing out enough gasoline through the tail pipe to fuel a flame so you’ll have to do something silly like make your engine less efficient or run in a second line of fuel to get these to work.
A single exhaust system is $125; dual exhaust is $200.

Think of it as evolution in action.
Well, I’m pretty sure carjackers would be scared shitless if they approached a car spitting flames.
back in the 60s, rodders used to just drill a hole and insert a diesel glow plug a few inches from the end of the exhaust. a little wiring and a switch, and you got the same effect… until the cops came.
Here’s a discussion on some different techniques (note: some foul language): http://www.jalopyjournal.com/forum/printthread.php?t=8017
Man I did this same thing to my K car (Dodge Aries) 15 years ago with a drill, a spark plug, wiring and a momentary pushbutton switch. It cost like $10 total. the glow plug above is probably a better solution, as the spark plug got clogged up pretty quick.
This is a GREAT idea, make your car burn more gas, which is going to be $5/gallon soon. Plus, you could start fires and look forward to all sorts of liability claims.

In Africa, they sell a similar device, but instead of shooting out of the tailpipe, the flames shoot out from under the sides of the car. Why? To deal with carjackers. Makes sense to me.
Oh, and SE7A7N7, if you’re driving a carbureted car, you’re not using more gas, you’re burning the gas you would have wasted! So, if your car has a carburetter , you should be obligated buy one of these…. ;P
How come auto exhaust Flame Throwers are never Today’s Woot? Or any Flame Thrower for that matter; Flame Throwers are just criminally overlooked by the people at Woot!
… this will work well on my old moped, i think…
Oh, great. I see more brush fires coming this summer….
You have to de-tune the carburetor so it’s running really rich. There’s not normally enough unburnt gas in the exhaust to throw flames. There has to be something really wrong. So indeed you are burning extra gasoline.
man. i have the autoloc flame thrower on my 77 4×4. its great. itll shoot up to 20 feet. and you can get a remote and set it off up to 30 yards away. and ya know what if your the kind of people worried about a fire. your probably not doin it at the right time
it doesnt need to be running rich! what the system does is when you push the button, it cuts off power to the ignition system and turns on the spark plugs in the tailpipe(s). this causes the engine to exhaust unburnt fuel because the engine ignition is off. you can only push the button momentarily because if you hold it, itll kill the engine (obviously). this is a great kit and a friend of mine has it, but i made my own from radioshack parts. (i.e. a relay and a switch)
