Every day we get calls from customers wanting the cheapest converter we have for their vehicle. We all want to save money when getting our vehicle fixed...but shopping for the cheapest catalytic converter might just turn out to be a very expensive experience.
What determines the cost of a catalytic converter is not the outer steel of the case or the pipes attached, it is the substrate (the guts or inside) of the converter. Inside a converter is a ceramic substrate, similar to a loaf of bread.This substrate is coated from the factory with a liquefied mixture of platinum, palladium, rhodium and cerium. These are classified as precious metals and are very very expensive. Example: On the metals market today Rhodium and Platinum are almost the same price as Gold!
The amount (total grams) of this substance or "wash coat" as it's called, determines the eventual pricing of the 
converter. The more wash coat the better the converter performs and the more likely it will KEEP THE CHECK ENGINE LIGHT OFF! The less wash coat, the less efficient the cat will work and the likelihood is that CHECK ENGINE LIGHT PROBLEMS WILL SOON RETURN!
Factory converters come with 70+ grams of precious metals coating on the substrate. This is an overkill of coating but you must remember factory converters carry an 8 year or 80,000 mile warranty. Catalytic Converters from Converter Warehouse all carry a minimum of 45+ grams of precious metal coating on their substrates. This is also an overkill of wash coat for an aftermarket cat, but it keeps the check engine light off and keeps your peace of mind! Nothing is more frustrating that buying a new converter and 60 days later have the Check Engine light reappear and then have to get another cat...no fun!!
Many suppliers on the web today sell off shore manufactured cats, from places like China, Korea, Philippines etc. These converters have minimal precious metals content thus making them initially nice and cheap, but here's the bad news...they don't work!! Unfortunately this does not only apply to foreign made converters, there are manufacturers in the states that skimp dramatically on the amount of wash coat. It does make their converters sell cheap but again how will they perform after installation is the real question? Remember, the less wash coat of precious metals the more likely the check engine light will come back! If you're buying an aftermarket cat you might want to ask the question of just how much wash coat the converter might contain? If they don't have an answer keep shopping!
So now we get back to "if you're looking for a cheap catalytic converter"? Chances are you will surely find one on the internet that is cheap...but will it do the job and will you be buying another one again real soon? Any small savings you might have achieved originally can become real expensive down the road!
