Magnaflow 09-16 BMW Z4 L6 3.0L OEM Grade / EPA Compliant Direct-Fit Catalytic Converter

Magnaflow is well-known for making exhaust components that sound great and perform well. For your 2009-2016 BMW Z4 with the 3.0L engine, their 21-171 Direct-Fit Catalytic Converter is built to keep your emissions system in check and your check engine light off. This converter is designed to meet federal EPA emissions requirements for OBDII vehicles, so you can be confident it's legal for use in most states.

This converter is made with strong 16-gauge 409 stainless steel tubing that resists corrosion, helping it last a long time. Magnaflow uses advanced 3D scanning during development to ensure this part fits exactly like the original equipment, making installation straightforward. Since it's a direct-fit design, there's no cutting or welding needed – it bolts right up. The single laser fusion weld is designed to prevent leaks, and its compact, low-mass construction helps with thermal efficiency.

When you install this converter, you'll find it includes a flange gasket and a Torca clamp to help make the job easier. It's designed to replicate the flow dynamics of the original part, so you shouldn't see any negative impact on your car's performance or fuel efficiency. Just remember, this converter is EPA-compliant but not CARB approved, so it cannot be shipped to California.
