MagnaFlow Nissan D21 Direct-Fit Catalytic Converter

If you're working on a 1988 or 1989 Nissan D21 and need to replace the catalytic converter, this MagnaFlow Direct-Fit unit is a solid choice. It's built to meet California Air Resource Board (CARB) requirements, meaning it's legal for use in California and other states with strict emissions standards, and it's designed to help keep that check engine light off.

MagnaFlow uses free-flowing, mandrel-bent tubing made from corrosion-resistant stainless steel for durability and longevity. The converter itself replicates the original equipment's spun body design, and a single laser fusion weld is used to greatly reduce the chance of exhaust leaks. This compact, low-mass design also helps with thermal efficiency. Because it's a direct-fit unit, installation is straightforward – no cutting or welding is needed, and it comes with the necessary gaskets to ensure a proper seal.

This converter is the result of MagnaFlow's advanced research and development, using 3D scanning to ensure it fits and functions just like the original part. It's a well-built replacement designed to meet or exceed emissions standards.
