how safe is it to have a flamethrower exhaust kit? what is the worst that could happen? anyone have an idea

 

Id say pretty unsafe. Fire is never really safe.

 

not to mention they are illegal in alot of states.

 

if you get a good kit your safe but most if not all, relign on fuel from the tank being injected into the exhaust to creat the flame so you cant really drive around like that

 

By what I understand, the flames are created by unburned fuel in the pipes. That is why the engines are reved up a few times before hitting the ignitor. Then, the plug fires and burns the fuel that otherwise would just drip out the tailpipe. Now, as far as being safe, there is a slight possibility of back burning in the pipes, which can screw up the muffler or cat, or exhaust valves, depending on your exhaust.

I always thought that it would be cool to melt the front bumper off of a civic or some other car with the flames, but that runs you into something slightly illegal.

 

brando, thats the other type of kit. one uses extra fuel in the exhaust (only works with no cats) and then there is the way that i said with the fuel line in the exhaust.

i guess if you think about it, its not that dangerous. if it was, hot rodders wouldnt have been doing it all these years

 

I dont think hot rodders buy flame throwing kits..... My friend has a 48 Chevy Stylemaster with the stock engine he completely restored and Flames just straight up shoot out the side pipes occaisionly, Its loud as all hell and its so badass. Too bad its a 3 spd on the steering colum, they dont sell a floor shifter kit for that year.

 

the kits that have a constant flame coming out need fuel injected into the pipes.

last time i went to the track there was a guy with a flame kit on his car. he never fired it up but he had spark plugs in his tips so it was pretty obvious

 

Oh.... so to get a constant flame they have the kits....Eh well the short natural bursts of fire are still cool as hell

 

they usually work by shutting down the spark to a cylinder or two and letting the fuel build up in the pipes, then a sparkplug type thing in the tailpipe lights it.

It's not a good idea to have the spark cut from your cylinders and have raw fuel going into you exhaust manifolds or headers......they tend to get pretty hot and can ignite the unburned fuel causing all kinds of problems.
