An old catalytic converter can lead to several issues, including reduced engine performance due to increased back pressure, which hinders exhaust flow. It may also cause the vehicle to fail emissions tests, as it becomes less effective at converting harmful pollutants. Additionally, a worn catalytic converter can result in poor fuel efficiency and potentially trigger the check engine light, indicating underlying problems. Over time, it may even become clogged, leading to engine overheating or damage.
That depends on the engine and the fuel you've used. If the engine starts burning oil a catalytic converter can fail rapidly. Some fuel additives can also cause a catalytic converter to fail prematurely.

The catalytic converter on a 1994 Buick LeSabre can be removed to be replaced. It cannot be removed permanently from the vehicle. Removing the catalytic converter will cause the vehicle to not run properly because there are oxygen sensors attached to it that the car needs. Also, removing the catalytic converter permanently may violate state laws against pollution in some states.
I have done the research and here are some online websites that can help you find a catalytic converter www.autopartswarehouse.com/catalytic_converters~pop.html
Yes, a catalytic converter can influence the smell of exhaust fumes. If the converter is functioning properly, it helps reduce harmful emissions and can eliminate some of the rich, fuel-like odors. However, if the catalytic converter is failing or there's an issue with the engine, such as incomplete combustion or fuel mixture problems, it may lead to a richer smell in the exhaust fumes. In such cases, addressing the underlying issues can help mitigate the odor.
Some of them depending on where sold and size of machine
Some symptoms of a bad catalytic converter on a 1994 Lumina are engine stalling, engine backfiring, no start of engine, and poor power pick up. If the catalytic converter has rust holes, the vehicle will also be very loud when running.
All O2 sensors (AKA Air/Fuel sensors) are threaded into the exhaust system. Some before the catalytic converter (upstream) and some after the catalytic converter (downstream).
The price varies from vehicle to vehicle. Some are very expensive and some are not.
Almost all cars have only one catalytic converter. Some can have two, four, etc.
Should you cut off the catalytic converter? No. But can you and will SOME vehicles actually benefit? Yes. It is illegal to remove any emmision control device from your vehicle in most if not all states. For countries such as Mexico where it is not illegal, some vehicles without downstream Oxygen sensors (after the catalytic converter) it can have some benefits. It is really the same benefit as a free flowing exhaust. Modern (97+) cars already have a free flowing design catalytic converter so there is no benefit to doing this.
The 2003 Hyundai Tiburon typically has one catalytic converter. However, some models may have additional components in the exhaust system, such as a pre-catalytic converter or a secondary catalytic converter, depending on the engine configuration. It's always best to consult the vehicle's service manual for specific details related to your model.
