Has Anyone ever used the o2 simulator device when you do away with the cataletic convertor.
If So anyone know where to purchase them...

leave your 1st o2 sensor in place, your 2nd o2 sensor can be spaced out so that it is not fully in the stream of the exhaust. You should be fine using this method.

You're going to be the guy with the loud, smokey, smelly tib. Keep your cat, or buy a new one if something is wrong with yours.

 

Ok smokey and smelly are not words that would fit that.

 

smokey and smelly is how you define a hippy not a exhaust cool.gif

 

DTN says that in any thread that has anything to do with not having a cat.

Our cars run rich. Our cars have alot of unburnt hydrocarbons. This means not all fuel is burned in the chamber. This also means that gas is shot out our exhaust. Gas has a smell. When heated up gas turns grey. You will have a car that smells like it's running rich. You will have a car that puffs grey smoke out the tail pipe. Your car will be louder then it was before.

 

^^dude that just happend to you, i havent ever seen another hyundai with that problem other then yours.....(the smoking part not the loudness, cause if you take off cats it gonna be real LOUD.)

 

I gaurantee that if you take both of the converters off the car and rev it to 5,000 RPM, you will see a puff of grey smoke. There's a reason our cars need 2 to meet california emissions control specs.

 

i had no cat, no resonators, and a straight thru muffler and i could rev it all day long and there was no gray smoke. smelled a little fuel like, but so does any exhaust, even with a cat..

you gotta take your theorys of what will happen and actually test them before you tell people WHAT will happen if they take their cat off. no one cares about california emissions specs except californians.

i know of a few people WITH a cat, and the car smells rich.. explain that? and please dont say, maybe they have bad cat, or they installed it wrong, or pull some crazy quote from wiki or google.

fyi, when a car runs rich, its black smoke.

 

^^OK, basically, you are saying that you don't care why their car was smelling rich, nor why their catalytic converter was not doing it's job, you are just stating that they had a catalytic converter that was not doing it's job.

This is your car with no catalytic converter right?

Looks kinda like a car with no cataltyc converter to me.

I'm done arguing. You can say what you like after this. There's a reason it is mandated that gasoline vehicles are required to have catalytic converters by law. Catalytic converters remove unburned hydrocarbons (fuel) from the exhaust and turn them into non-volitile substances. Non-catalytic exhausts will emit chemicals that smell bad and will burn your eyes. Catlatyc converters remove that.
