Using this MagnaFlow catalytic converter is straightforward. First, make sure your vehicle is in the compatibility list. If it is, you'll need to perform cutting and welding to install it properly. We recommend having a professional mechanic handle the installation if you're not experienced with such tasks. When using your vehicle, this converter will work silently in the background to keep your check - engine light off. As for maintenance, keep an eye on it during regular vehicle check - ups. If you notice any signs of corrosion or damage, have it inspected immediately. Since it's made of stainless steel, it's quite durable, but proper care will extend its lifespan. Also, always ensure that your vehicle's exhaust system is in good condition to avoid any additional stress on the converter.
