An aftermarket direct-fit catalytic converter for 1999-2003 F150 and F250 4WD trucks with the 5.4L V8. It uses a stainless steel shell and ceramic substrate, with the oxygen sensor port placed to match the factory exhaust routing so it bolts into the stock location. It is EPA federal compliant but not legal for California-registered vehicles or CARB states like New York, Colorado and Maine. It suits owners replacing a failed converter on an otherwise healthy truck; gaskets and clamps are not included, and misfires or oil burning should be fixed first or the new unit will fail quickly.

This direct fit catalytic converter is an aftermarket replacement for 1999 to 2003 F150 and F250 4WD trucks with the 5.4L engine. It has a stainless steel outer shell and a ceramic substrate to handle everyday exhaust temperatures and reduce harmful emissions.
It is built around the factory 5.4L 4WD layout. The oxygen sensor port is positioned to match the original exhaust routing, so it installs in the same location as the removed unit. The substrate loading is tuned to help keep the malfunction indicator lamp off when the original failure was converter related.
The formulation is Federal EPA compliant. It is not legal for sale or use on California registered vehicles and is not intended for CARB required states such as New York, Colorado or Maine. Before ordering, verify the truck is 4WD, has the 5.4L V8, and uses the same flange and pipe diameter as described in the fitment line. Confirm the year range and cab configuration where needed. Professional installation is recommended. Address engine misfires, rich running or oil burning before installation, since these problems can quickly damage a new converter.
