So you are equating the sulfur smell and content of diesel (which is higher than gasoline in the first place) to the unusual sulfur smell resulting from more than one persons installation of new exhaust systems/converters? That makes sense.
You can dance around how smart or correct you are without trying to get proven wrong by not actually posting facts in this thread, but thats ok. Lets see if you can answer a simple question that this thread poses: the poster installs a new exhaust system to include catalytic converter, and all of a sudden his vehicle exhaust smells like sulfur. You are going to blame this on the fuel when his location, source of fuel, and type of fuel haven't changed or are unknown? Tell us ALL how you arrived at the conclusion that the fuel is the cause of the smell if the fuel hasn't changed. Heck, I bet if we ask, the poster had the smell with the SAME tank of gas used before and after the exhaust swap! You think? Not only that, more people post the same results from the real world as he has. If the smell isn't coming from the catalytic converter, where is it coming from?
You can choose to ignore everything that contradicts what you think you know, you just won't learn anything. Unfortunately for you and your theory in this case, I'm not the only one that has "experienced" this, yet you choose to ignore them as well. Not only do you dismiss the possibility, you fail to actually prove anything, or offer any other alternatives. Your post here follows the same path as the other post you linked to, lack of technical information, no proof to back up your statements, and fear of being proven wrong. You might want to stop being so proud of posts that prove exactly that. Heck, this thread is just another example of you getting involved solely to take away from the original post.
As with any other post you felt the need to steer away from the original issue to deal with your personal vendetta, I'm done with this one unless someone else posts. There's nothing to learn from someone that doesn't post anything informative.
As to diesels not having converters, might want to talk to the europeans about how they haven't been using them for years.
See what happens when someone never went to college. They have an ego trip.
Lets take the last quote.
"europeans about how they haven't been using them for years"
i dont care if europe does or what you said "havent" used converters.
Look at my quote "semi's" i dont live in europe. DUH So how would i know what a european semi truck smells like.
reading comprehension?
So you want me to back up everything i said. Let me just scan my BS diploma for you.
heres a nice quote
Newer vehicles are designed to operate on a very specific air-fuel ratio. Fail to properly maintain your vehicle and any one of several components in its electronic fuel management system can fail upsetting its air-fuel ratio. Sulfurous odors can often be traced to one of the sensors used by your vehicle’s computer to maintain desired fuel control.
The catalytic converter uses various noble, precious metals to perform its emissions reduction and prevent odors. Exotics like platinum, palladium, and rhodium. If too little of one of these precious metals was used during the manufacture of your converter you may experience odor even though fuel mixture is correct. A deficit of catalytic reaction compounds can cause a converter to drop below the minimum threshold for odor control.
wow it says fuel mixture can cause a sulfer smell. There goes your theory that a catalytic converter can be the "ONLY" cause of rotten egg smell. Eventhough, gas still has sulfur in it. Which your link proved. So did Diesel. But i thought your theory is "many things can be wrong"
And because your idea of diagnostics is to replace parts first, instead of identifying the problem. According to you, it is smarter to replace an expensive catalytic converter then to diagnose why a "cat" failed in the first place. Is that where you get your experience from and others that believe replacing parts is better then fixing the real problem?
"many people put new aftermarket cats on and have an odor problem" that is your experience LOL
Just like the link i provided last time, and the quote above. Still believe cheap aftermarket cats work? If you had any experience or equipment (which is more then a test light) you would be able to see how great your aftermarket cat is working. I doubt you can afford a 5 gas exhaust analyzer to "Prove" your experiences of how well an aftermarket cat works.
So what is your experience in why a CAT causes rotten egg smell? Put a new cat on a truck. It smells bad, just because it is new. Then it goes away after a while. So what is the educated answer? new converter = bad exhaust bad converter = good exhaust ?
You must have a lot of experience in destroying aftermarket converters. LOL
So why does it smell like eggs when it is new??? I need an educated answer besides "it is normal" because it happens a lot to backyard mechanics.

uh yes. If there was no sulfur in gasoline or diesel, then there would be no smell. How can you have the sulfur smell if chemical reactions have no sulfur molecules to interact?
And why would the government try to regulate the sulfur content and reduce the PPM of sulfur in automotive/truck fuel?
lets see you walk around that LOL talk about europeans again. Europeans dont have a high sulfur content maybe that is why their fuel don't emitt a noticable odor.
Me not backing up my info LOL go read the last link about cats. You got all huffy puffy about being wrong. Then "trying" to make yourself look good. You tried to make an excuse that my link isn't updated. ROFL
well, im off to talk to the europeans about their diesels that "haven't" been using catalytic converters for years. ROFL
