2000 Catalytic converter
I have a 2000 4.6l Efi Expedition / 175000 miles. Alldata lists the part number for the bank one Cat as XL3Z5G21
A. My question is does anyone know if the cats are the same for the 4.6 and 5.4? Thanks in advance

I would guess yes. If you need a cat just get a magnaflow-probably less $ and better flow. You could always ream out the smaller "pre" cat which is located just forward of the main cat. You will pass emissions with flying colors.
