Because a failing catalytic converter can no longer properly convert the toxic fumes that flow through it into less harmful materials, one of the side effects that you are going to experience is the smell produced by the gases flowing through it. In particular the exhaust is going to have a sulphur type smell.
Among the bad symptoms of a compromised catalytic converter are: Sluggish engine performance, Reduced acceleration, Dark exhaust smoke, The smell of sulfur or rotten eggs from the exhaust, Excessive heat under the vehicle, Some of those symptoms can also be caused by other parts of the emissions system, so it’s …
In the case that the catalytic converter is totally plugged, it will prevent you from running your vehicle. In some situations, it may come to be completely fused directly or overtime, and it will need to be replaced immediately.
Catalytic converter replacement isn’t cheap. For most vehicles, the average cost of a catalytic converter repair is between $945 and $2475 including parts and labor. The catalytic converter cost itself can be up to $2250 of that.
Check engine light turns on
Usually, an illuminated check engine light is the first and only sign of a bad catalytic converter. When the light pops on, your car’s engine control module (ECM) will also store a diagnostic trouble code (often a P0420 code) in its memory.
You can unclog a clogged catalytic converter only in case of light damage. … Cleaning or replacing a faulty catalytic converter while ignoring the causes won’t solve the issue in the long run. It will leave you with another clogged catalytic converter that will again have to be replaced in another costly procedure.

The check engine light often appears if your catalytic converter is clogged, although since the O2 sensor reports slower (because it measures efficiency over a longer period of time than other sensors), you might get a “check engine” light for something else like engine misfires, before you get a check engine light for …
A clogged catalytic converter makes the engine work harder, which in turn makes it difficult to shift the transmission. In regards to air, a bad O2 sensor or dirty mass air flow sensor will also cause the gears to stick.
A clogged converter can cause rough idle, engine hesitation upon acceleration, weakened power, hard-starting and, in some cases, a no-start condition. … This symptom can be diagnosed by using a vacuum gauge on the intake manifold, or an exhaust back-pressure pressure gauge before and after the converter.
As a general rule, yes you can drive without a catalytic converter. Driving without a catalytic converter will not damage the engine or the car in any way. However, it may be illegal to drive without a catalytic converter in your state and it is likely that your vehicle will fail an emissions test.
A bad catalytic converter can impede the natural flow of exhaust emissions exiting a car’s engine, thereby increasing the amount of back pressure within the car’s engine which can lead, ultimately, to overheating. … Any blockage or obstruction along the way can cause huge problems for a car’s engine.
A catalytic converter is a device used to convert harmful compounds in your car exhaust into harmless compounds. … If you are replacing your old catalytic converter, don’t leave it with the mechanic or muffler shop.
The cars most likely to suffer catalytic converter theft
Which?’s figures show that the Toyota Prius, Toyota Auris and Honda Jazz are the most commonly targeted models, with Admiral also reporting many examples of the Lexus RX being singled out.
Check Engine Light Comes On
A bad or failing catalytic converter can also cause an illuminated Check Engine Light. … 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 second sensor is screwed into the exhaust pipe right past the catalytic converter. … Rather, there could be something else in that system does that’s causing the oxygen sensors to appear faulty. This is actually the case with most check engine codes.
A clogged catalytic converter blocks exhaust flow, resulting in a loss of power and acceleration. If the restriction is severe enough, the engine may not run. … If the needle on the gauge drops slowly to ~10 “hg while increasing the engine speed to 2500 RPM, check the exhaust for a clogged catalytic converter.
The quickest temporary solution is to remove the front oxygen sensor. This will create an exhaust leak before the back pressure builds up against the clogged converter. An exhaust leak is loud and everyone is going to know that you have a problem with your car the second you start it.
Cost to replace the catalytic converter of your car
Mainly because of the precious metals that are included in the converter, such as platinum, or platinum-like material such as palladium or rhodium. So, the more expensive the material, the more expensive it is to replace.
The cat will only affect emissions and as long as it is plugged, there won’t be drivability issues. The alternator going out won’t charge the battery and run the system.
If you car doesn’t move when you step on the gas pedal, this is usually an indication of a fuel system issue. However, it can also be an indication of engine problems or a stuck emergency brake. Typically before acceleration failure, you may find that your vehicle’s engine runs rough or frequently stalls.
A failing car’s catalytic converter will create a significant backpressure that lowers your car’s engine performance. Whenever this happens, you will notice your car shaking frequently, and if there is a sudden outburst of pressure, the engine can stall even when on the road.
1. Reduced engine performance. One of the first symptoms commonly associated with a bad or failing catalytic converter is a reduction in engine performance. … Both can negatively affect engine performance and can cause a reduction in power and acceleration as well as fuel economy.
Bad spark plugs or damaged exhaust valves can also destroy a catalytic converter. It is important to keep your engine and fuel injection system in good working condition. … However, if your converter is completely clogged, your engine will quickly fail because of all of the exhaust back pressure.
One of the most common causes of a sputtering engine is an issue with the vehicle’s fuel system—the filter, pump, and injectors. … Since the fuel filter, pump, and injectors work together as part of one interconnected system, dirt and debris need only clog one part to cause the others to fail.
Originally Answered: Can you replace a catalytic converter with a straight pipe? Yes. However, it will then fail any safety inspection. If your locale does not require testing for exhaust emissions, you should be OK.
California became the first state to require the use of CARB-compliant catalytic converters on January 1, 2009. In subsequent years, other states including New York (6/1/2013) and Maine (6/1/2018) mandated the use of CARB-compliant converters for certain model year vehicles.
