3 Reasons to Upgrade to the 1999-05 Hyundai Sonata Catalytic Converter 452020 by MagnaFlow

The direct-fit MagnaFlow catalytic converter 452020 is worth trying out for your 1999-05 Hyundai Sonata 4Cyl 2.4L, especially if you are thinking about considerably upgrading its power output. Your stock catalytic converter may not have the capacity to cope with the greater volume of exhaust gases that your engine is producing. So your stock converter may be obstructing your car’s performance. This bolt-on MagnaFlow catalytic converter delivers a higher flow of exhaust gases, which is likely to translate to better performance. You can have this high-flow catalytic converter for just $739. In this article, we will discuss some of its benefits as we consider the following:

1. What is a Catalytic Converter?
2. What are three reasons to upgrade?
3. Why buy the California MagnaFlow catalytic converter 452020?

What is a Catalytic Converter?

A catalytic converter is designed to rearrange the chemical makeup of harmful exhaust gases coming from the engine, changing them to less harmful gases. The converter comes imbued with precious metals like platinum, rhodium, or palladium that act as chemical catalysts. When the exhaust gases, which may consist of carbon monoxide, nitrogen oxides, and hydrocarbons, come in contact with these precious metals, they convert into less harmful gases like carbon dioxide and nitrogen.

What are three reasons to upgrade?

Fuel Economy

If your car’s fuel economy is not as high as it was before, try adding the California MagnaFlow catalytic converter 452020. Over time, catalytic converters can get clogged or plugged up because of bad spark plugs, incorrect engine timing, inaccurate air/fuel mixtures in the engine’s fuel combustion chambers, and many more. When clogged, the converter expels exhaust gases at a much slower rate, causing exhaust fume up within the engine and decreasing the amount of oxygen it can burn with fuel, which results in poor fuel economy. This expensive catalytic converter features unrestricted mandrel-bent tubing and a core with more passages for enhanced exhaust gas flow. Therefore, this product is sure to do a better job of preventing exhaust fume buildup, so it will help your engine achieve a more balanced fuel/air mixture, and ultimately, better fuel economy.

EPA Carbon Emission Standards Compliance

MagnaFlow has designed this catalytic converter to meet the Federal emissions standards set forth by the EPA. Thanks to its richer constitution of expensive chemical catalysts, it will refine the exhaust fumes coming from your engine more competently and ensure that you pass any mandatory periodic carbon emissions inspections carried out in your state.

Better Performance

The performance mods you have added to your car may have boosted its performance to a certain degree, but they can achieve even more performance with the help of the MagnaFlow catalytic converter 452020. In helping your engine to put out exhaust fumes quicker and more efficiently, this product will enable your machine to achieve its untapped performance potential, depending on the modifications you will have made. It will allow for a richer air/fuel mixture in the motor, resulting in greater power output.

Why buy the MagnaFlow catalytic converter 452020?

Built to last:

This product’s stainless steel construction promises rust-free operation at high temperatures. Also, the different sections of this MagnaFlow catalytic converter 452020 have been joined using single laser fusion welding, which is more exact and yields greater tensile strength than that of TIG welding.
