Using your MagnaFlow catalytic converter is straightforward, but it does require some basic mechanical skills. First, since it's a universal design, you'll need to cut and weld it to fit your specific vehicle. Make sure to measure carefully before cutting to ensure a proper fit. When installing, follow your vehicle's repair manual for the best results. As for maintenance, it doesn't need a lot of attention. Just keep an eye on the check engine light. If it comes on again, it could be a sign of other issues with your vehicle, not necessarily the catalytic converter. Also, avoid driving through deep water or mud as this can damage the converter. If you live in an area with harsh winters, road salt can speed up corrosion, so it's a good idea to wash the undercarriage of your vehicle regularly to extend the life of the converter.
