Magnaflow 04-05 Chevrolet Impala 3.8L Direct Fit Converter

This Magnaflow direct-fit catalytic converter is built with 410 stainless steel hangers and 16-gauge 409 stainless steel tubing, offering strong corrosion resistance for a long service life. It’s designed to meet or exceed California Air Resource Board (CARB) requirements, making it legal for use in California and other restricted states. The converter replicates the original equipment’s spun body design, featuring a single laser fusion weld to significantly reduce the chance of exhaust leaks. Its compact, low-mass construction also contributes to greater thermal efficiency.

Magnaflow uses advanced 3D scanning during their research and development process to ensure this converter fits and functions just like the factory part. The free-flowing, mandrel-bent tubing is engineered to maintain factory performance and fuel efficiency, helping to keep your check engine light off. Installation is straightforward, as this converter is designed as a direct-fit replacement, meaning no cutting or welding is required. It comes with the essential gaskets needed for a proper seal, simplifying the installation process for you.
