MagnaFlow Conv DF 00-02 Audi S4 2.7L Driver Side

If your 2000-2002 Audi S4 is showing a check engine light related to emissions, it's likely time to replace the catalytic converter. This direct-fit converter from Magnaflow is built to keep your car running cleanly and legally, specifically designed for the S4's 2.7L engine. It's made to meet Federal EPA emissions requirements, so you can be confident it'll pass inspection.

Magnaflow uses a strong 16-gauge 409 stainless steel for the tubing, which holds up well against corrosion and ensures a long service life. The company uses advanced 3D scanning to make sure this converter matches the original equipment's fit and function, replicating the OE spun body design. This attention to detail, along with a single laser fusion weld, greatly reduces the chance of exhaust leaks. The tubing is mandrel-bent to maintain the factory design and geometry, and the compact, low-mass body helps with thermal efficiency. You'll also find that installation is straightforward, as it's designed as a direct bolt-on replacement with no cutting or welding needed. Magnaflow includes the necessary gaskets to help you get a proper seal right away.

This converter is designed for Federal/EPA emission systems. It's important to note that this part is not CARB approved and cannot be shipped to California. By using this direct-fit converter, you're getting a well-built replacement that aims to restore your vehicle's emissions performance.
