Using your MagnaFlow universal catalytic converter is straightforward. First, check if your vehicle is on the list of compatible models. Once confirmed, professional installers will need to use welding, cutting, and tube - bending equipment to fit it properly. When installing, make sure all connections are tight to avoid exhaust leaks. As for maintenance, it's a good idea to have it inspected regularly, especially if you notice a change in your vehicle's performance or a strange smell. Keep an eye on the engine light; if it comes on, it could be related to the catalytic converter. If you live in an area with a lot of stop - and - go traffic, consider getting it checked more often. With proper use and care, your MagnaFlow catalytic converter will serve you well for a long time.
