Using the MagnaFlow catalytic converter is straightforward. First, make sure your vehicle is one of the listed compatible models. Since it's a universal design, you'll need to do some cutting and welding to fit it properly. If you're not experienced with this, it's best to get a professional mechanic to handle the installation. As for maintenance, it doesn't need much special attention. Just keep an eye on your vehicle's performance and the check engine light. If the light comes on again, it might be a sign that there's an issue with the converter or elsewhere in your exhaust system. Also, try to drive your vehicle regularly to keep the catalytic converter working well. Avoid using low - quality fuel as it can damage the converter over time. That's all you need to know to get the most out of your MagnaFlow catalytic converter.
