Having done it myself, I sometimes wonder what the actual catalytic converter replacement cost is. The short answer is… IT VARIES. Replacing a catalytic converter means you can expect to spend anywhere between $400 and $1800 dollars (for most cars). If you own a Ferrari or Rolls Royce, well you shouldn’t even be wondering what the cost is. For most cars, if you were to canvass some local dealers or auto repair shops, here are some sample prices you might come across:
- Shop No. 1: $1,595
- Shop No. 2: $750
- Shop No. 3: $495
Keep in mind, these are prices for the exact same car. As you can see, prices can vary tremendously. You may even go on Craigslist or have a buddy do it for a couple hundred dollars. Aside from parts, certain cars are much harder to work on than others. You will usually pay a premium if your car has various under body covers which first need to be taken off. A check engine light reset will also need to be done in most cases.Common or Generic Catalytic Converters
The common (or generic) catalytic converter is the type most often used for basic sedans and other popular vehicle models. This is a two-way version that has the simplest conversion process. Generic catalytic converter prices are typically in the range of $150-$500. Keep in mind that if your car has duel exhaust, you will most likely need 2 catalytic converters those prices double. Most car owners are not aware of the cost and for most cars, this is on the low end.
High End Catalytic Converters
These high-end catalytic converters make use of the three way version on some engines. These are designed for larger engines and for greater efficiency. High end converters are usually more expensive and are available for between $400 and $900 in a typical replacement cost. Some may even cost upwards of $2,000. Aftermarket versions, on the other hand, can commonly be found for less than a hundred dollars. However, the cost of the converter replacement may rise quickly, especially if a lot of welding needs to be done.
Below are a few sample prices for specific car models:

Toyota Corolla

Nissan Maxima
- Direct Fit Catalytic Converter $90 to $350
- Universal Catalytic Converter $70 to $630
Honda Accord

Honda Civic

Subaru

Contributions to Catalytic Converter Replacement Cost
The cost for the replacement of a catalytic converter usually includes a warranty as well. For example, the Federal Emissions Warranty makes it cheaper to purchase a catalytic converter in case the car has not yet reached eight years or 80,000 miles. Other contribution to costs usually includes varying labor costs and individual state taxes. As a rule of thumb, the rarer or older the car model, the more-expensive the replacement will cost. This is applicable not just for catalytic converters but for any other-parts of the car as well. By older, we’re not talking about a 10 year-old car. Think 50 years or more.

Maintenance
This refers to the cost of keeping the catalytic converter operating properly and efficiently and to make sure that the cost of the replacement is avoided. Catalytic converters rarely malfunction. Most of the time, maintenance of spark-plugs can be common as well as the maintenance of other basic components, but these are done to ensure that the catalytic converter remains efficient. However, most converters are prime targets for thieves because of the amount of money they can get for the scrap metal. Other than parking in a garage or area where theft is unlikely, there is only so much you can do when a criminal will resort to cutting out the cat converter with a blowtorch. Catalytic converter theft continues to be a big problem, especially in this economy.
As a car owner, it is necessary to make sure that all the components of a car are kept in good working order. As you may have noticed, replacing a catalytic converter can be quite costly so you have to make sure that you maintain its condition. It is also necessary that you are aware of catalytic converter symptoms so that you can have it repaired immediately before it results to further damage that may require replacements. Regular checkups of the engine and the rest of its components can help you prevent having to spend that much.
When the catalytic converter needs to be replaced, make sure that you get a good amount of quotes before deciding on a shop or dealer. This can make it easier for you to determine if you are being charged more than how much you should really be paying for. Too many people simply think that the first price they are given is what the norm is. For an expensive part like this, it really pays to do your homework. The final catalytic converter replacement cost should always include parts and labor, but expect to pay more if additional repairs are needed.
