CARB Catalytic Converters

Designed to reduce harmful emissions by converting toxic gases into harmless substances, like nitrogen oxides into nitrogen and oxygen, catalytic converters are essential for the wellbeing of our planet. Before you make your purchase from AutoAnything, first you must identify the kind of emission system your vehicle came with. There are a few ways to tell, but if yours meets CARB regulations, then you need a CARB catalytic converter.

Your vehicle's clean performance and fuel efficiency is due in part to its exhaust system, including parts like the pollution reducing catalytic converter that is responsible for lowering vehicle emissions in every modern car.

What Is a Catalytic Converter

Vehicle exhaust systems used to produce a wide range of toxic hydrocarbons that contributed to pollution in cities across the country. Catalytic converters are largely the reason this is not the case anymore. They use a catalyst that reacts with those toxic chemicals to break them down into gasses that are natural in the earth's atmosphere, like water vapor and carbon dioxide. In many areas, a carb approved catalytic converter is required to make sure the vehicle's converter performs to the requirements of the local environmental regulations.

How To Keep Your Catalytic Converters in Great Shape

As you might imagine, even a carb legal catalytic converter can malfunction if it is overwhelmed by too many exhaust fumes or by the wrong kind. To keep your catalytic converter in good shape, you need to keep your engine and exhaust system in good shape. When the engine burns lubricants or gets contaminated with fluids that should not be present, the makeup of the exhaust changes. This, in turn, changes the performance of the converter. In some cases, it can cause buildup that renders the converter inoperable. Immediately addressing issues with exhaust flow and engine performance will help your converter last as long as possible.

Signs Your Catalytic Converters Are Going Bad

The most telling signs of a failed carb compliant catalytic converter are the scent and color of the exhaust. Malfunctioning converters fail to break down heavy gasses that produce dark exhaust fumes with a sulfur smell, like rotten eggs. Other unconventional scents like a sweet burning smell can also occur if the exhaust is polluted with compounds that the engine should not be burning.

You also need to be on the lookout for less obvious signs that could point to more general exhaust issues as well, like sluggish engine performance and reduced fuel efficiency. They can tell you something is wrong before the exhaust changes color or smell, giving you time to order a converter before it is obvious yours is malfunctioning.

Magnaflow Universal Catalytic Converters - CARB


In California, trying to find a cat at a reasonable price is unheard of. So when I found this one, I just couldn't believe the quality or pricing was real. However, when it arrived, I took it to my muffler guy and he confirmed that it was a certified legal part. He installed it and did the reset. NO MORE LIGHT! AND, it passed the smog test the next day!

Magnaflow Direct-Fit Catalytic Converters - CARB

Good quality, great price compared to OEM

Great quality part from Magnaflow- solid fit & finish! Most places had quoted $1800 to replace the driver's side cat- getting this from AutoAnything and having a Toyota/Lexus specialty shop install it saved me $600. Also- be sure to write down the CARB ID on the part because you will need it when you take the car to get smogged. View more reviews...
