MagnaFlow Conv DF BMW 5 99-00 Driver Side

If your 1999-2003 BMW 540i is showing a check engine light related to emissions, it might be time to replace the catalytic converter. This direct-fit converter from Magnaflow is designed to get your car running cleanly again and keep that light off, all while meeting Federal EPA emissions requirements. It’s built to function just like the original equipment, so you can be confident in its performance and fit.

Magnaflow builds this converter with strong 16-gauge 409 stainless steel tubing, which is really good at resisting corrosion and should last a long time. They also use a compact, low-mass design that helps it reach optimal operating temperature quickly for better thermal efficiency. The single laser fusion weld is designed to prevent leaks, and they've replicated the OE spun body design for a familiar fit. Because it's a direct-fit unit, installation is straightforward – no cutting or welding needed, just use the proper tools. Magnaflow includes the necessary gaskets and hardware, so you won't have to reuse old, potentially corroded parts.

This converter is specifically made for Federal/EPA emission systems. It's important to note that this part is not CARB approved and cannot be shipped to California. If you're looking to restore your BMW's emissions system to proper working order with a well-built, direct-fit replacement, this Magnaflow converter is a solid option.
