Find Your Next Catalytic Converter
Catalytic converters are a key part of the exhaust system on most modern vehicles. They are typically located on the underside of your car or truck between the engine exhaust manifold and the muffler. Catalytic converters serve as an important line of defense when it comes to protecting the environment from detrimental exhaust pollutants. If it is time for a replacement, you can visit your local AutoZone or shop on our website for some of the best catalytic converters for cars and trucks.

An Essential Piece
When your vehicle's engine burns fuel, it generates several types of harmful byproducts including carbon monoxide, nitrogen oxides and hydrocarbons. Carbon monoxide is a poisonous gas that is toxic to humans and other creatures, while hydrocarbons and nitrogen oxides are major causes of smog, acid rain and other forms of environmental degradation. Catalytic converters substantially reduce the emission of these pollutants by chemically converting them into less hazardous substances such as oxygen, carbon dioxide, water vapor and nitrogen gas.

Keep an Eye on Problem Areas
So how do you know when it is time for a catalytic converter replacement? In most cars and trucks, the check engine light should appear with a code to notify you if your catalytic converter's efficiency is measuring below standard. Even so, it is always wise to be closely attuned to the performance of your vehicle so that you notice indications of a problem early on. Common signs of issues might include a sudden drop in fuel efficiency, difficulty starting the engine, black smoke coming from the exhaust pipe or a sluggish feeling when driving. Oftentimes, people will postpone replacing their catalytic converter because they are filled with questions like, “Is it that bad to drive on a faulty one?”, or “Where can I even find catalytic converters near me?” However, at AutoZone, we offer a variety of catalytic converter replacements that are easily accessible in-store or with free one day delivery. Driving with a bad catalytic converter for too long may eventually lead to an engine shutdown, so never delay in replacing it.

When It's Time for a Change, Look AutoZone's Way
It is important to be aware that catalytic converter troubles could be symptomatic of other complications within the vehicle. Converters are susceptible to overheating if engine misfiring causes unburned fuel to enter the exhaust system. Coolant or oil entering the engine's combustion chamber can also clog or degrade the catalytic converter. Hence, you may want to investigate whether the failure is due to age or something more. Whether you are a DIY car guru and want to tackle catalytic converter replacement on your own or would simply prefer to have a mechanic install the part, AutoZone's gets your replacement to you in no time and offers some of the lowest prices on catalytic converters that you can find anywhere. No matter where your car repair journey takes you, AutoZone has got you covered when it comes to providing affordable parts.
