MagnaFlow Conv DF BMW 01-03 525 2.5L / 01-03 530 3.0L California - Rear

The stainless steel construction on this Magnaflow catalytic converter is built tough, using 16-gauge 409 stainless steel tubing that's highly resistant to corrosion. This is important because catalytic converters live a rough life under the car, exposed to road salt, moisture, and heat cycles. Magnaflow replicates the original equipment's spun body design, and uses a single laser fusion weld to greatly cut down on the chance of leaks. This means you get a solid seal and better thermal efficiency, helping the converter do its job effectively.

This converter is designed as a direct fit for your 2001-2003 BMW 525i (2.5L) and 530i (3.0L). Magnaflow uses advanced 3D scanning during their research and development to ensure the part fits just like the original. Installation is made simpler because it's a direct-fit unit, meaning no cutting or welding is required – just bolt it on using the proper tools. Plus, it comes with the necessary gaskets and hardware, so you won't have to worry about reusing old, corroded parts or making a separate trip for installation supplies.

This Magnaflow converter is specifically built to meet or exceed California Air Resource Board (CARB) requirements. It's undergone extra testing to comply with CARB guidelines, making it legal for use in California and other states with strict emissions regulations. This ensures your check engine light stays off and your vehicle passes emissions tests.
