MagnaFlow Conv DF 86-89 Nissan D21

If you're working on a 1986-1989 Nissan D21 and need to replace the catalytic converter, this direct-fit unit from Magnaflow is a solid option. It's designed to meet federal emissions requirements, helping to keep your check engine light off and your truck running cleanly. Magnaflow builds these with free-flowing, mandrel-bent tubing to ensure exhaust gases can exit efficiently, which helps maintain factory performance and fuel economy.

What's great about this converter is that it's made to fit right in place of your original equipment, meaning no cutting or welding is needed for installation, just a straightforward bolt-on job with the included gaskets and hardware. The construction uses 16-gauge 409 stainless steel tubing for good corrosion resistance, and the welds are durable 308 stainless steel. Magnaflow uses 3D scanning during their design process to make sure the fit and function are as close to the factory part as possible, and the single laser fusion weld helps prevent leaks.
