Hello and Welcome to Justanswer,

My name is XXXXX XXXXX I am here to try and assist your with your question.

The Cat converters on your 2003 are serviced as an assembly, both converters and the Y Pipe are one unit from the Factory. I have enclosed the Factory replacement instructions, let me know if you need more help.

Ron the bank 1 cat converter is the one that is connected directly to the exaust manifold between the fire wall and the engine, not the y pipe.
Expert:  Ron replied 6 years ago.

Yes that is correct but they are not serviced as seperate units, the are made on the Y pipe for both bank one and bank two as one assembly.

The picture on the answer you just sent me doesn't match the part I'm replacing. the part I'm replacing looks like an exaust manifold attached to a catalytic converter.
Expert:  Ron replied 6 years ago.
The instructions I sent is for the Y pipe assembly which has both the bank one and bank 2 converters built on to it , the cats do not unbolt from the Y Pipe, its one assembly . If you are replace the Bank one Cat this it the correct procedure, are you sure your replacing the Cat?
Customer: replied 6 years ago.
Yes I'm replacing the cat. This vehicle has 3 catalytic converters on it. Bank 1, Bank 2, these have sensors on them and then there's a third converter on the exhaust pipe.
Expert:  Ron replied 6 years ago.
The HO2S sensor are mounted in the Exhaust pipe on the Y pipe just ahead of the Cat , then the Y Pipe hooks to the manifold and the Cats are part of the Y Pipe and not serviced seperate, they have be replace as one assembly with the Y pipe. .

Maybe it'll help if I give you the part number, it's 16223, it comes of the back side of the engine to the y pipe.
Expert:  Ron replied 6 years ago.
The part number isnt a valid part number, The Y pipe bolts to the exhauxt manifold on both sides. If the Bank one converter can be replaced seperate than the Y pipe still has to come off. Depending on weather you have the 4 valve or the 2 valve engine, here is what they look like.
