Catalytic converters often clog up because people are driving the car a lot and are not aware that the catalytic converter has to be run at specific temperatures in order for it to work.
Running the car at short distances and in bumper-to-bumper traffic all the time will guarantee that the catalytic converter will get clogged up.
So, to avoid this happening to you, you will need to make sure that you drive your car every once in a while on the highway at higher RPM for a couple of minutes.

To add to the problem, Hydrogen Sulfide is colorless, which makes it hard to detect for sure.
Whats really concerning about the gas is its very poisonous when breathed in.
Add to that the gas is flammable too. Hydrogen Sulfide gas doesnt easily disperse either.
Even a few breaths of it can cause confusion and a loss of taste and smell. This makes it potentially deadly if the main sense smell that would warn you of this danger is now not working correctly.
Even providing ventilation may not be enough to remove a pool of gas. As its heavier than air, it may still sit below a window level and not be dispersed if indoors. Always best to open a garage door if you suspect its present.

Inhalation of hydrogen sulfide can also be detrimental to your health. But short-term exposure of extremely low concentrations emitted by your car is unlikely to cause any ill-effects.

- Irritated or watery eyes
OSHA limits a persons exposure to hydrogen sulfide of up to 8-hours when a concentration of 10 ppm is present in the workplace. Consult your medical provider if you think you are experiencing symptoms of hydrogen sulfide exposure.

The metal parts inside the engine are also spinning faster due to increased pressure on them with an increase in RPMs, too! When either one happens, itll create heat that causes the oil within these components to break down into sulfur-containing compounds that then produce odors strong enough to fill your vehicle with bad smells.
Unless you have a leak in the transmission fluid, you wont smell such odour as the transmission fluids remain well-sealed.

One Reason When Your Car Battery Should Smell Like Rotten Eggs
Now, if youre really into battery maintenance, there is a thing called equalization or desulfation. Both of which are basically a controlled overcharge to either bring the individual cells to an equal state or to agitate and break off any sulfation that has occurred on the plates.
Many but not all smart chargers have this feature and it also is sometimes called recovery mode.
Smart chargers will carry out the process automatically without need the need to intervene. However, this process can take up to 8-10 hours with some models which Im just not a fan of. I dont care to have my battery boiling for that long and risk the heat evaporating all of the electrolyte, bulging my battery, poisoning my household or worse.
If you monitor the process with a voltmeter, youll see the process get well into the 16.5-volt range. Anything over 14.5 or so is getting into the overcharge range. 16-volts and higher and youll hear the electrolyte boiling from 30 feet away.
When Ive done a desulfation mode process, I stopped it after 30 minutes. You can do what youd like though. I just dont like the risk and I no longer perform it as a maintenance measure. Some people swear by it, youll just have to do your own research and weigh the risk to reward ratio.
