Magnaflow 87-91 BMW 325 2.5L CA Direct Fit Converter

When it's time to replace the catalytic converter on your 1987-1991 BMW 325i, 325is, or 325iX, this Magnaflow California Grade Direct-Fit converter is a solid option. It's designed to meet California Air Resource Board (CARB) requirements, meaning it's legal for use in California and other states with strict emissions standards. This converter is built to keep your check engine light off and ensure your vehicle passes emissions testing.

What you get in the box is everything you need for a straightforward installation: the converter itself, two nuts, two flange gaskets, two donut gaskets, a Torca clamp, and two bolts. Magnaflow uses free-flowing, mandrel-bent tubing made from high-strength 409 stainless steel, which resists corrosion and helps maintain factory performance and fuel efficiency. The collector design is precisely stamped for optimal exhaust flow, and the compact, low-mass design allows for better thermal efficiency. Magnaflow uses durable 308 stainless steel MIG welds and a single laser fusion weld that significantly reduces the chance of leaks, replicating the original equipment design for a proper fit and function.

This converter is designed as a direct fit, meaning no cutting or welding is required for installation, making it a job you can likely handle yourself with the right tools. The included Torca AccuSeal exhaust clamps are designed to provide even clamping force all around the pipe, preventing distortion. By replicating the OE design, Magnaflow ensures this converter will fit and function like the original part.
