GMC Catalytic Converter Buying Tips
What is a Catalytic Converter?
The job of the catalytic converter is to turn noxious exhaust gases (hydrocarbon, carbon monoxide, and nitrogen oxide) into less harmful compounds for safer, cleaner emissions. As an unburned gasoline, hydrocarbon is one of the harmful exhaust gases that can produce smog. Carbon monoxide is formed during the combustion of fuel and is known to be poisonous, while nitrogen oxide is a result of the heat in the engine forcing oxygen and nitrogen to merge, creating smog and acid rain.
The catalytic converter uses a catalyst (such as platinum, rhodium, and palladium) to turn carbon monoxide into carbon dioxide, while hydrocarbon is broken down into carbon dioxide and water and nitrogen oxide into nitrogen and water. If it fails to do this job, it's time for you to get a new GMC catalytic converter that can execute the mission well.
Here are some tips:
Make sure that the new catalytic converter meets the EPA(Environmental Protection Agency) guidelines and other requirements.
The catalytic converter that you'll get as a replacement must meet all the EPA requirements and comply with the standards. The catalyst in the device should be able to convert toxic compounds into less harmful gases through for safer, cleaner emissions. But while EPA may have the guidelines, catalytic converters vary when it comes to construction and flow. Also consider the state regulations. If you live in California, for instance, make sure that the device is CARB-approved.
Look for a top-quality catalytic converter.
Catalytic converters are all designed for the same purpose but they're not created equal. Search for a catalytic converter that's durably built. Some, for instance, are constructed using a heavier-gauge stainless steel. The best options are those that ensure better, smoother flow, designed with less restrictions to the exhaust. Some of the devices are tested and have been proven to have smooth or high flow.
Choose between a universal cat converter and a direct-fit cat converter.
Universal catalytic converters are designed to fit several makes and models. But the universal design, however, doesn't mean that they'll be a perfect match to all kinds of automobiles. The catalytic converter of a 4-cylinder engine-equipped vehicle, for instance, differs from that of the V8-powered automobile. Even if you're looking through universal cat converter options, you have to be sure that the size and design of the device meets the specs of your vehicle. Shop by make, model, and year to be sure.
You can also ask the seller or consult the manufacturer about the application.Direct-fit
catalytic converters are designed for a specific make and model. Since they are guaranteed to fit perfectly, you can rely on their straightforward installation. They match the size and all the dimensions of the original equipment.
Take your pick between OEM and aftermarket.
Some car owners choose OEM parts because they naturally fit better and are easier to install. Basically, you're replacing the old stock with the same thing-identical fit, form, and function. If your vehicle has modified engines or you drive an older car and the device is no longer produced for this model, aftermarket cat cons are your best options. Some aftermarket catalytic converters are even designed to be less restrictive compared to the original equipment. They're built for higher flow, which leads to increased horsepower and torque.
