The Walker Ultra 53569 is a direct-fit, three-way catalytic converter for 2008 Ford F-150, Expedition and Lincoln Mark LT trucks with 4WD. It bolts on with a two-bolt spherical flange inlet and a slip-fit outlet, so no welding is needed. It is EPA-compliant but not CARB-certified, so it cannot be sold or registered in California or other CARB states. It suits owners replacing a failed or rusted converter on an older truck who want a bolt-on part rather than a universal weld-in unit.
