The catalytic converter itself is a part of the exhaust system. They almost always have a heat shield around them and an oxygen sensor somewhere before them. It is necessary for the catalytic converter to be before the muffler. The muffler is really the only thing that you can confuse for the catalytic converter on your Ford Focus.
The catalytic converter may be bolted or welded on depending on the year and make of the vehicle. The catalytic converter for your Focuss cost will vary by model year and engine size.
But, as a rule catalytic converters are not cheap. Time to raise your standards. Catalytic converter quality varies, as does the caliber of the work being performed.

Think of the catalytic converter as the cheat sheet you snuck into your Biology exam in high school.
Its entire purpose is to help you pass a test. If your car fails its emissions test, it could be because your catalytic converter is letting you down when you need it most.
We get it. Your car is fun. A malfunctioning catalytic converter can decrease the power your car has, and even lead to stalling, or an inability to start. Ahh, yes. Your favorite warning light to completely ignore. The check engine warning light can illuminate for many reasons, including a catalytic converter that forgot how to work. There are already roughly 50 million feral cats in the country, so the last thing you want is yours running around, getting busy, and bringing more kittens into the world.
Oh, sorry, you meant getting the other cat fixed. Either fault can negatively affect engine performance and cause a reduction in power and acceleration as well as fuel economy. Rattling noises from under the vehicle are another symptom of a bad or failing catalytic converter. If a catalytic converter becomes old or damaged internally from excessively rich fuel mixtures, the catalyst coated honeycomb meshes on the inside of the converter can collapse or break apart, causing a rattle.
The rattle may be more obvious when starting the vehicle and will worsen over time. During engine combustion, sulfur-containing gasoline becomes hydrogen sulfide. A properly working catalytic converter will convert hydrogen sulfide into odorless sulfur dioxide. When failing, you may notice a sulfuric, rotten egg-like smell coming from the exhaust. Unburnt fuel left in the exhaust by the bad catalytic converter produces the odor, and may even cause dark exhaust smoke.
A bad or failing catalytic converter can also cause an illuminated Check Engine Light. The oxygen sensor and air-fuel ratio sensor in modern vehicles monitor the efficiency of the catalytic converter by tracking the gas levels in the exhaust. If the computer detects that the catalytic converter is not operating correctly, or not catalyzing the exhaust gases properly, it will set off the Check Engine Light to alert the driver of the problem.
A variety of other issues can activate the Check Engine Light, so it is recommended to have the vehicle scanned for trouble codes to be certain of the issue. Some states in the U. Should this pop up, the car will fail the test.
The catalytic converter is one of the most important emissions components found in modern vehicles. Without it, the vehicle may produce excessive emissions harmful to both humans and the environment.
