Interesting, an exhaust would throw flames if there was fuel in there somewhere.

umm flames? does he litterally mean flames? don't think thats likely. the only way i see it being possible and i could be wrong, but i see it like this: is gas is unused/your running rich, and the fumes they ignite. now what does the ignition come from? you need a spark like from a sparkplug...




oh and yes its probably bad. cars arn't ment to throw flames out from anywhere last i heard.

Does your friend know the difference between flames and smog? Didn't think so. Also it could be the APC muffler you have, let me guess LEDs???

Its probally fireballs, FI cars doo this all the time, Just whatch Speed Channel and youll see, I dont think your car can throw a fire ball unless your boosted.

It shouldn't be a problem. It generally happens when your car is running rich and unburned fuel happens to head out your exhaust and ignites. No big deal.

The lack of a functioning cat is a big factor too.

Could be a problem if you drive through and area with a gas leak. =) Use the cat.

since you hallowed out your cat, there might be excell fuel being ignited and you are able to see it out the back. More of what your friends are seeing is probably a brief spark, not actually a flame, due to how wide open your exhaust is.

My bro has a VW GTI with the VR6 engine, and some other mods. Well, he took his cat off totally and it is pretty much just straight back. His does that quite often. Shouldn't hurt anything....just wastes fuel.

I've got no cat, am running quite rich, boosted, and have never once seen a flame.

Perhaps he's got a bad plug, which isn't burning the fuel in a cylinder?

wouldnt it be because of bad O2 sensors? they're misreading?

Well he is definately running rich. people that really know how to use their nitrous can flame at will a supra did it to me one night on the highway and i was like Daaaaaaammmmnnnnnn its Sick. but a NA car should not be that rich

i dont think it burns up ur gas mileage because its just burning fuel that goes through the engine that stays un burnt that a functioning cat would normally burn up

You are running rich on your fuel mix.......

Go ahead and bolt a sparkplug to your exhaust, near your tip...and wire it up to the middle console. Then, when you want flames, just touch the wire to a 9volt battery......

Cool idea, man. That would be fun.
My bro's car I was talking about is silly loud though to be able to do that. It is just straight back without a cat or mid-resonator. I don't like the way it sounds. It isn't a Maxima!!!

LastBoyScout

even witha stock setup you should be able to set you car's exhaust up to do this....... You just end up setting the car to run a little rich.....

perhaps you're backfiring?

BTW this thread is funny...fireball?

Then wouldn't all the people with test pipes have flames coming out their exhaust???

If they look like this G20 get some help! Seriously though, check your spark plugs, air filter, and put I'd the cat back in. I'd just keep it down around the police. (all engines will flame if the exhaust pipes are very short, why do you think lawmowers and snowblowers have a "spark arrester"?)

Hey boyscout, where would u mount the spark plug at? does the tip spark need to be inside the muffler somewhere or how would it work?
I have a test pipe on as of now and id like to see how this works while i got some free time coming up soon.
and which wire from the 9v to the what part of the sparkplug?
