California Grade Direct-Fit Converter

MagnaFlow 5582740 is a California Grade CARB-compliant direct-fit catalytic converter with an integrated exhaust manifold for front-position applications. It is built for a bolt-on installation on listed Honda and Acura vehicles, using stainless steel construction, a ceramic substrate, and OE-style spun body design to match factory fit and function.

This MagnaFlow California Converters part is engineered for drivers who need a direct replacement that aligns with California Air Resources Board requirements on the listed vehicles. The compact, low-mass design supports thermal efficiency, while the single laser fusion weld helps reduce leak points. MagnaFlow also uses 3D scanning during development to verify fitment against original equipment geometry.

Installation Notes

Install with proper hand tools; cutting or welding is not required. Use the included gaskets and mounting hardware to help achieve a secure seal and avoid reusing corroded factory fasteners. Verify the vehicle’s engine family, emissions certification, and front-position application before installation. This part cross-references Walker (e.g., 16346, 16446) for the same application.
