Exhaust Flame Thrower

exhaust flame thrower diagram

There are two popular methods for producing exhaust flames - we will explain them both here.

The means of producing flames for an exhaust flame thrower is the same for both methods. That is, a constant, pulsing spark ignites unburnt fuel at the end of the vehicle exhaust system. How you go about producing that spark and making sure you can produce flames is where the differences are found.

Exhaust Flame Thrower methods

Active Ignition

The Active Ignition method of producing an exhaust flamethrower involves installing and wiring the kit properly and the igniting the unburnt fuel. This kit works best on vehicles without a catalytic converter or with an older converter. Vehicles with large motors, power modifications etc. will produce good flames... often even with a catalytic converter. Using higher octane fuel can also make an impact on the size of the flame - as will altering the fuel mixture so that you are running rich. This kit will cause less wear and tear on the motor/exhaust system than the other method (method #2). flame thrower kit control box

The kit we sell from UltraGear is an Active Ignition kit.

PRO's: • Easier to install •does not cause damage to motor/exhaust system • does not affect how often you must change oil • very reliable when set up properly

CON's: • Catalytic converters MAY cause it to be less effective

Ignition Bypass

Ignition Bypass is a method of making flames by shutting down the vehicle ignition system which allows raw fuel to flow through the cylinders and exhaust system until it is ignited at the end of the tail pipe by the flamethrower kit. This method is used by many companies as it can produce nice flames with less tinkering...but, there can be problems. Because raw fuel is running down the sides of the cylinders, it can mix with your oil. You need to change oil much more often if you are using this system. Also, the fuel can damage rings etc. and ruin your catalytic converter over time. If you have a vehicle that you don't mind changing the oil often or maybe even doing repairs often - this kit is a good choice. Many people buy this type of kit for show type vehicles that they don't drive much.

On many vehicles (including almost every newer vehicle) the fuel pump will automatically shut off when the ignition is killed. In these situations, you will either have to switch to the Active Ignition method of producing flames or remove this safety feature from your vehicle (it may be difficult or impossible to remove). NOTE: WITH THESE KITS YOU WILL BE SHUTTING THE MOTOR OFF AND ON FOR EACH FLAME

PRO's: • Produces large flames when installed properly • produces reliable flames when installed properly

CON's: • Causes much more damage to the vehicle than the Active Ignition system • more complecated to install • may not work on newer vehicles • must shut engine off and on to operate
