An old hot rodder's trick from back in the day was put a spark plug right at the exhaust outlet. It's a bit of a task to mount it, and a bit more of one to fire it (don't mess with the vehicle high voltage system to do this), but it worked quite well. It isn't as dramatic as the flames the special effects (fx) dudes rig up 'cause they have large budgets and can actually mount injectors coupled to a fuel source back there as well as the firing mechanism, but it works. Be smart about this. The vehicle code places limits on this kind of thing. Oh, and IT CAN BE DANGEROUS! Think things through.
Here's the theory. There is a fair amount of unburned fuel (or, more properly, partially combusted fuel) in the exhaust stream, and the air that is injected into the exhaust header by the "smog pump" on newer cars (to aid in a bit more combustion for cleaner exhaust) will make for a nice show at the exhaust outlet. One more time: be smart about this. Ask around. Above all, be safe. You can be killed or injured fooling around with stuff that lies far outside your knowledge and experience. (Be honest with yourself.) And the chance for some major property damage looms high for the foolhardy. Do your homework. You been warned, ait?
I found this link that shows you how to make a kit similar to the one I made

Flame Thrower Kit Info
Here is a list of items you will need:
1. You will need a relay that they use at the stereo shop for alarms, make sure the relay has the numbers 87, 87a, 86, 85, 30 on it, if it doesn't then that is the wrong relay.
2. Go to Autozone or other parts store and get an old style coil that has the positive and negative on it just like the one from the old Ford F-150. If you go to Autozone, the part number is C-819 coil.
3. Coil wire for the coil about 3 feet long or longer if you can get it.
4. Spark plug.
5. A momentary switch.
6. Roll of 14 gauge wires in color Green, Blue, Black, Red, and Yellow
7. Wire connectors.
8. Black electrical tape.
How To Make The "Fire Box"
1. Take all the color wires and cut a piece of about 1 feet long of all colors. You should have 5 pieces of wire in 5 different colors.
2. Place the connectors on all 5 wires.
3. Connect the Green wire to # 87A on the relay.
4. Connect the Yellow wire to #87
5. Connect the Black wire to #86
6. Connect the Red wire to #85
7. Connect the Blue wire to #30
If you are going to sell the item, go to Radio Shack and get what is called a Project Box so you can put it inside that box and fill the box up with fiber glass resin so if they try to open it they will have to break it and will not know how to make one. :-)
Your fire box is ready. Make sure all wires are in the right numbers or it will not work right with these instructions.
Installing The Kit
1. Find a location for the relay or fire box under the dashboard.
2. Open your hood and look for your car's coil.
3. Once you find it you will have to look for the negative wire of your cars coil. The easiest way to do this is to take the coil you got from the store and connect 2 wires to it. Connect the coil wire to the coil and the spark plug to it. Now take the wire that is connect to the positive side of the coil and connect it to the battery. The ground side you will use to find what wire in your car's coil will make it spark.
4. Make a small slice cut on all the wires coming from your car to your car's coil (don't cut them). Start you car's motor and take the ground wire from the store coil and touch each one of the wires on your car coil till you see that the spark plug is firing. Once you've found it, cut engine off. Cut that wire.
5. Run a wire from your car's coil side of the car to where your relay or fire box will be located and connect it to the Green wire on the relay.
6. The wire that was coming from the car to the car's coil, run a wire from there to the relay and connect it to the Blue wire on the relay.
7. Find an ignition wire in your car (power when you turn the key) connect the ignition wire to the Red wire on the relay.
8. Mount your Switch, one side to ground on the car and the other to Black wire on relay.
9. Mount your store coil in the trunk close to your exhaust, drill a hole in your trunk, then drill a hole about 6 inches behind your exaust or muffler for the spark plug (becareful not to make it too big)
10. Run a wire from your car battery to the coil in the trunk, positive side of the coil.
11. Run the Yellow wire on the relay to the rear coil, negative side.
12. Start your car, in park. Take the engine to about 5,000 RPM and press and hold the switch, the engine should start to stall and and smile, YOU'VE GOT FLAMES!!!!!!!.
No Flames?
1. Try changing the wires around for the Green and Blue.
2. Make sure your engine is running rich.
3. Make sure the spark plug is firing (take it out and test it outside don't try to look in your exhaust)
4. Make sure you have no Catalytic Converter

Professoractually i haven't tested this method but I have two of them...
1.ok you will need a drill, a spark plug, a old coil, some old wires, a battery *if you don't already have one* (must be 12 volts), and a button.
ok so take your wires, battery, coil, and your button and connect your battery's negative terminal to ground and positive to the button and then to the coils POSITIVE terminal. take another wire and hook it up to the NEGATIVE terminal and then to ground. now you are almost done. take your drill and spark plug and drill a hole one inch from the end of the tailpipe. and screw in the spark plug. hook up the coil to the spark plug. start it up rev to approximately 5000 rpm and hit the button. POOF!
2. you will need a butain lighter the wind resistant type
rev your bike to approximately 5000 rpm and then put the lighter behind it and poof!
thanks for your time!

How do you make flames shoot out exhaust?
Flames shooting out of race car exhaust pipes is caused by unused fuel passing from the cylinder into the exhaust system and lighting by the heat of the exhaust. Race cars run a different grade of fuel than a normal passenger car so this is common. You have to really soop up a normal car engine for this to happen on a normal car.
What would make flames come out of tailpipe of 2000 Saturn SL2?
Often that can be the result of a sticking injector that puts too much fuel into the engine. The fuel will eventually burn somewhere, and that may be when it comes out the exhaust.
What ignites the exhaust fumes on race cars to make flames?
race cars run a very rich mixture. when the engine dies, the unburnt fuel in the exhaust system catches fire from the heat in the exhaust pipes. when the engine is refired, the fire blows out. Flames come out the exhaust during the deceleration of a racing car because during wide open throttle the intake manifold and intake port are filled with a homogenized air fuel mixture. When the throttle is suddenly closed the velocity of this mixture stops and the pressure drops into a strong vacuum. This causes the fuel to drop out of suspension (in the air) and return to a liquid state. This liquid fuel is drawn through the combustion chamber and ignites when it reaches the hot exhaust valve and pipes resulting in the visable flames from the end of the pipe.
Does the transmission make smoke come out of the tailpipe?
No, the engine exhaust is what comes out of the tailpipe.
How do you make your breasts grow when you're a teenager?
Boobs come naturally, boobs are just fat tissue developing in your chest. Eat and be health and they shall come naturally.
What ingredients do you need to make a mineral?
You can't make artificial minerals. Minerals come naturally.
How do you get flames on toribash?
Well, you used to be able to edit the item.dat folder, and change flame settings, but now you have to subscribe to the flame forge, which is where the flames come from. All flames cost 50k tc to make. Once you have made one, it will appear in your inventory, and you need to activate it. Flames also sell on the torimarket for around 70k to 400k, depending on how famous/awesome it looks.
Will an exhaust leak make my check engine light come on?
Possibly. What an exhaust leak will do is KILL you. Either from the Carbon Monoxide you inhale while driving or the wreck you are going to have when it puts you to sleep. Get the exhaust leak fixed ASAP.
What makes fire come out exhaust when shifting gears?
Is you question about how do make it have fire come out or is it why does fire come out. I can answer both just let me know which one you want answered
What makes flames come out your exhaust?
Usually a product of valve overlap and exhaust. It's basically unburnt fuel coming through and igniting on the hot exhuast tip when it hits the air at the end of the exhaust pipe. In aspirated cars it's large valve overlap which helps scavenging and performance in the top end. Turbo cars, due to the large amounts of fuel at full noise. Normally happens after high RMP then throttle snapped shut.
How do you make yourself wet when you finger yourself?
It will come naturally if you are turned on enough. Relax and enjoy.
