"I went to the dealer and two mechanics trying to get my check engine light diagnosed properly they all told me it was my Bank 2 front Cat. So I purchased this part and installed it. Nothing has changed and my vehicle is still throwing the same code. I am sure if my vehicle needed this part it would be a great purchase. The job itself is pretty difficult with typical hand tools. I would not attempt again. It took me 5 hours. This item comes with the necessary hardware but the nuts that came with this did not fit the studs that it also came with. We had to run down to the store and purchase the correct nuts. That was kind of annoying. Overall the quality is decent and it is exactly the same size and shape as the OE part." posted by: JB on October 13, 2009
