Magnaflow Conv DF 04 Forester 2.5L Rr CA

This is the Magnaflow California Grade CARB Compliant Direct-Fit Catalytic Converter, part number 451008, specifically designed for your 2004 Subaru Forester with the 2.5L engine. If you're in California or another state with strict emissions requirements, this converter is built to keep your check engine light off and ensure your vehicle passes inspection. It's designed to be a direct replacement, meaning no cutting or welding is needed for installation, making it a straightforward job with the right tools.

Magnaflow put a lot of thought into making this converter perform well and last. They use free-flowing, mandrel-bent tubing to ensure your exhaust gases move smoothly, which helps maintain factory performance and fuel efficiency. The construction is from highly corrosion-resistant stainless steel, so it can handle the elements and resist rust over time. They also use advanced 3D scanning during their design process to make sure the fit and function are just like the original part. The single laser fusion weld is designed to greatly reduce the chance of exhaust leaks, and its compact, low-mass design helps with thermal efficiency.

When you get this converter, it comes with the necessary gaskets and an O2 port plug, simplifying the installation process. This part has undergone additional testing to meet or exceed California Air Resource Board (CARB) requirements, making it legal for use in California and other CARB-restricted states for your specific vehicle.
