Nissan Frontier Catalytic Converter - MagnaFlow - Direct Fit - 05-06. A California-grade, direct-fit replacement designed specifically for 2005-2006 Nissan Frontier models, engineered to meet emissions requirements while restoring proper exhaust flow and helping prevent check-engine light issues tied to a failing converter.
This MagnaFlow unit (California Grade, part number 5481668) reproduces OE spun-body geometry and uses mandrel-bent tubing and corrosion-resistant stainless steel to provide long service life and consistent flow characteristics. The compact, low-mass design and a single laser fusion weld reduce leak points and improve thermal efficiency. The converter ships with the necessary gaskets and hardware to simplify installation — no cutting or welding required when fitting the compatible exhaust flanges. It is designed to meet CARB requirements for applicable vehicles; legal installation requires that the vehicle’s Executive Order (EO) number and Engine Family Number (EFN) appear on the converter’s CARB Executive Order.
