MagnaFlow Conv DF BMW 99-00 323 2.5L / 99-00 328 2.8L / 99-00 Z3 2.5L/2.8L California

If you're working on a 1999-2000 BMW 323i, 328i, 528i, or Z3, and need to replace the catalytic converter, this MagnaFlow California Grade CARB Compliant Direct-Fit unit is built to meet strict emissions standards. It's designed to keep your check engine light off and ensure your vehicle passes emissions testing, especially in California and other CARB-restricted states. This converter is a direct fit, meaning it's made to bolt right up to your existing exhaust system without the need for cutting or welding, simplifying the installation process.

MagnaFlow constructs this converter using highly corrosion-resistant stainless steel tubing, specifically 16-gauge 409 stainless steel, which helps ensure a long service life. The tubing is mandrel-bent to maintain a consistent diameter, promoting free-flowing exhaust gases for optimal performance and fuel efficiency, similar to the original equipment. The spun body design replicates the OE style, and a single laser fusion weld is used to greatly reduce the chance of exhaust leaks. Its compact, low-mass design also contributes to better thermal efficiency. This part is designed to meet or exceed California Air Resource Board (CARB) requirements and has undergone additional testing for legal use in those states.

When you install this catalytic converter, you won't have to worry about reusing old, corroded hardware. MagnaFlow includes the necessary gaskets, bolts, and hardware to help ensure a proper seal and a leak-free installation. This direct-fit converter interchanges with several OE part numbers, including 11 62 1 439 859, 11 62 1 732 935, 11 62 7 503 673, and 11 62 7 503 674, making it a reliable replacement option.
