With features including free-flowing mandrel-bent tubing and highly corrosion resistant stainless steel construction, easily install this converter yourself using the proper tools, no cutting or welding required. MagnaFlow's state-of-the-art metrology department uses the latest 3D scanning systems during research and development, so you can be confident that your new part will fit and function like the original equipment. By replicating the OE design, the single laser fusion weld greatly reduces the possibility of a leak, and our compact, low-mass design also allows for greater thermal efficiency. This Direct-Fit Catalytic Converter is designed to fit the 2003-2004 Lincoln Navigator 5.4L. MagnaFlow 4583029 interchanges with OE parts 2L7Z-5E212-AB, 3L7Z-5E212-EB, 4L7Z-5E212-AB. This replacement part is designed to meet or exceed California Air Resource Board requirements, and has undergone additional testing to comply with CARB guidelines to allow for legal use in California and CARB restricted states, for the listed vehicles.

Customer Reviews (4.8 / 5 · 5 reviews)

Aurora ★★★★★

The mandrel-bent tubing made a noticeable difference in exhaust flow, and the check engine light has stayed off since installation. Fit perfectly on my 2004 Navigator without any modifications needed.

Nicholas ★★★★★

The direct-fit installation was straightforward on my 2003 Navigator, and it's a relief to have the check engine light finally off. The corrosion-resistant stainless steel gives me confidence it'll last through many more California winters.

Eli Q. ★★★★★

Took about two hours to swap on my '03 Navigator in the driveway, and the mandrel-bent tubing lined up perfectly with the factory hangers. No more P0420 code, and the exhaust note is actually a touch deeper now. Went through smog last week without a second look.
