Hello there You are true that your car has two catalytic converters: one that is located in the exhaust manifold and is frequently referred to as a pre-catalyst, and a second converter that is located farther “downstream” in the exhaust system. The second converter, which includes oxygen sensors before and after it, is the one that typically causes a “under-efficiency” problem. The “pre-converter,” which is a component of the exhaust manifold, is subject to a Nissan Recall (Recall 03V084000) and may be changed as a result of that Recall. Consult your local Nissan dealer if you’re unsure about whether this repair has been made. If the second converter does need to be changed, I advise having it done by a skilled, mobile mechanic from YourMechanic who will visit to your home or office, evaluate the issue, and provide you with an accurate assessment of the damage and cost estimate for repairs.

Can I change my own catalytic converter?
Maybe you’ve observed that your car isn’t running smoothly anymore. Your fuel efficiency seems to be less than typical. Even a bad stench coming from the exhaust could be detected. It is obvious because the check engine light is also on. It’s time to start planning the replacement of your catalytic converter right now. Cost is important because, depending on the make, the part alone can cost anywhere from under $100 to $2,000 or more.
You stay near the lower end of the range if your vehicle is an older model or a diesel. The north end can be reached by a more recent vehicle, such as a Toyota SUV. Fortunately, because less time is required, the labor cost is lower.
The part itself accounts for the majority of the expense of replacing your catalytic converter. It is one of those things that could make the job unworkable. That may influence your decision to forego it and look at new car or used truck prices instead.
Usually, getting there doesn’t take much effort. The component is right there in plain view because it is situated between the exhaust manifold and the muffler. Usually, the repair takes less than an hour. Depending on how it’s attached to the vehicle, you can either do it or you can’t.
Many automakers will weld components into place. The catalytic converter replacement process will probably take longer if yours is OEM. To make the repair, the old one will need to be removed using a Sawzall. Where the rubber hits the road is there. If you have the necessary equipment and knowledge, you can complete the task and save yourself about $100 on labor.
A catalytic converter may be bolted into place on some cars. It now falls under the DIY category. The likelihood of the hardware being rusty increases the difficulty of the repair. Using penetrating oil, the job can be completed quickly. However, if a bolt breaks or you are unable to remove them, you are left at a loss and must return to the store.
A catalytic converter is simple to replace. One piece of specialist equipment, which costs under $20, is necessary for the process. What you’ll need is as follows:
- Set of ratchets and sockets
- oil that penetrates
- Jack postures
- substitute catalytic converter
- sensor socket for oxygen
Purchase the proper component for your vehicle’s make, model, and year. Instead of buying rebuilt, buy new. Place all four wheels of your car on the jack stands to begin. Before you start working on it, let the air circulate to cool off the components.
Track down the catalytic converter. The oxygen sensor and its connections must then be removed using the unique socket. Then, working from the back and moving forward, remove the bolts at the flanges using a ratchet. Do not pressure them. Spray penetrating oil on them as an alternative, and then give it some time to work. Give it one more go.
Then, all that remains is to replace the worn-out component with the new one. The oxygen sensor and its fittings should be changed. You’re ready to go once the catalytic converter is firmly installed.
As you can see, the fix is simple. The only things that make it more difficult and lengthen the catalytic converter replacement process are rusty bolts or a welded component. The task is easily manageable by a do-it-yourself mechanic.
When you’re finished, turn on your car to make sure the check engine light is off. It may indicate a damaged catalytic converter, but it may also indicate an issue with the oxygen sensor. Use a diagnostic scan tool to see if further repair is necessary. You might find it useful.
The catalytic converter in your car is crucial for minimizing the poisonous emissions that contribute to air pollution and climate change. Fortunately, there is a quick repair that won’t take much time. To catch any issues early before they worsen, pay attention to any odd sounds or odors coming from your car.
How much would it cost to replace the catalytic converter on a Nissan Altima?
Nissan Altima catalytic converter replacements typically cost between $1,739 and $1,786. Between $142 and $180 is the expected labor cost, and between $1,596 and $1,607 is the projected cost of the parts.
Do Nissan Altima models from 2006 have catalytic converters?
The 2006 Nissan Altima is the only vehicle for which this direct-fit catalytic converter was created. The included gaskets and hardware eliminate the need to reuse corroded OEM parts during installation while lowering the likelihood of a leaky seal.
Reduced performance and/or starting problems
Your catalytic converter’s ceramic honeycomb structure is prone to deterioration, corrosion, and fragmentation. Age, external factors, or other factors may be the cause of this. As a result, the catalytic converter may clog and obstruct the usual passage of exhaust gases through it and the rest of the exhaust system. This will have a direct impact on the engine’s performance, possibly to the point where you can’t even start your automobile. You might observe:
- Misfiring
- inadequate power
- sluggish acceleration
- Stalling
- No start for the engine
- decreased fuel efficiency
- Hesitation
- the requirement to accelerate more quickly to achieve a sufficient level of power
A rattling sound from underneath your car
You might hear them rattling around inside your catalytic converter when the engine starts, runs, or when your automobile hits a bump or a pothole if the ceramic particles inside of it fragment into smaller pieces.
A sulfurous, rotten egg smell from your exhaust
After the fuel-air mixture is burned in the cylinders, the sulfur in your gasoline is converted into foul-smelling hydrogen sulfide gas inside your engine. The hydrogen sulfide is transformed into the odorless sulfur dioxide when your catalytic converter is operating normally. A defective catalytic converter won’t be able to process the hydrogen sulfide, therefore it will exit your exhaust unprocessed and smell strongly like rotten eggs.
Your Check Engine light comes on
All of the emissions-related equipment in your automobile is continually being monitored by the engine computer. The Check Engine light on your dashboard will come on if the computer determines that your catalytic converter is malfunctioning. A mechanic can retrieve a trouble code that will also be shown on the computer. This will assist the mechanic in identifying the precise source of the issue.
You fail an emissions test
If you live in a region where your automobile must undergo emissions testing, you can learn that your catalytic converter is defective when your car fails a required smog or vehicle emissions test. This could be as a result of the test finding a catalytic converter-related issue code in your engine computer, in which case your Check Engine light is likely lit, or as a result of the test finding an excessive amount of unburned fuel in your exhaust.
How can a catalytic converter be fixed without having to buy a new one?
Try driving your car for a few tanks of high-octane fuel, for instance, if you usually fill it up with the cheapest low-octane fuel. At your next fill-up, you might also try adding one gallon of lacquer thinner to ten gallons of gasoline to remove catalytic converter deposits.
How long do I have until I need to replace my catalytic converter?
You can keep driving a catalytic converter indefinitely. You won’t be able to start your car if the catalytic converter is completely blocked. It may become totally fused in some circumstances, either instantly or over time, and will need to be replaced.
Can I use a straight pipe in place of my catalytic converter?
You might be wondering if installing a straight pipe can help you avoid the pricey replacement of a new catalytic converter due to the high repair expenses of replacing a stolen one.
Can you install something quickly so that my car won’t sound like a 747 jet airliner when I drive it?
Installing a straight pipe, also known as a test pipe, will cause you to fail any emissions testing or smog inspections. This is so because the main function of a catalytic converter is to change hazardous emissions from gasoline-powered engines—like carbon monoxide—into more environmentally friendly gases—like carbon dioxide or water vapor.
Due to the rich metals they contain, catalytic converters are frequently targeted by criminals who can quickly cut off and take one. Due to the rising cost of the rare metals used in many catalytic converters, there has been a sharp rise in the theft of these devices in recent years.
Simply jacking up your car, cutting it loose from the exhaust pipe, and driving off are thieves. Here is more information on catalytic converter theft.
The removal of a catalytic converter from your exhaust system is prohibited in all 50 U.S. states, regardless of whether you worry about passing emissions tests or live in a state where an emission test is not necessary.
Additionally, most trustworthy mechanics won’t operate on your exhaust or muffler unless they are replacing the car’s catalytic converter in the future.
And forget about selling or trading in your car, truck, or SUV; unless you can find a third party buyer ready to buy it, you won’t be able to do either.
Without a catalytic converter, what does an automobile sound like?
Can I drive without a catalytic converter? is a common question that many customers ask when faced with the recovery costs of a stolen “cat?
Both yes and no are the responses. A automobile can theoretically run without a catalytic converter. This, however, is not a viable long-term solution. Here are several issues that arise when you drive without a catalytic converter.
Loud Vehicle Noises and Missing Catalytic Converter
Extremely loud engine noises are the first indication that a catalytic converter has been stolen. Driving without a catalytic converter may cause your car to sound like it is roaring, especially when you start it or give it gas.
Rough Driving and Acceleration
Your car will drive rougher as your exhaust isn’t controlled. Normally, your engine pushes exhaust through the catalytic converter. Without this part, the intense exhaust push will result in unpleasant acceleration that is uneven.
Annual Vehicle Inspection Failure
You will fail both the NC safety inspection and the NC emissions inspection if you don’t have a catalytic converter. You might be asking why a missing catalytic converter would result in you failing your safety inspection, even though the failure of the emissions check may seem evident.
An exhaust system check is part of your annual safety inspection, and it specifically looks for components that have been altered or removed. Among others, this pertains to your catalytic converter, muffler, exhaust pipe, PCP valve, and EGR valve.
As a result, without a catalytic converter, you will not be able to renew your vehicle’s registration. On our list of everything checked during your yearly safety inspection, you may find more details on exhaust system inspections.
Harmful Car Emissions
Because it transforms pollutants into less dangerous byproducts like water vapor and carbon dioxide, your catalytic converter is termed as such. Without this part, your automobile won’t be able to filter and reduce dangerous emissions including carbon monoxide, nitrogen oxides, and hydrocarbons. This not only harms the environment, but it can also result in dangerously low air quality. For instance, these dangerous contaminants may enter your home when you park in your garage.
