I have a 2003 with the 4.6L that is throwing the PO430 code(Catalyst system efficiency below threshold Bank 2). Now I have read that these have a pre-cat then the cat and was wondering if anyone had a picture of the pre-cat? Can I just remove the pre-cat and replace it with pipe when I replace the cat? Does it in fact have a pre-cat or not? I am debating whether to take this somewhere or do it myself. Thanks in advance.
