Replacing Catalytic Converter
I bought the Direct replacement converter by Walker, and put it on tonight.
Issues that I found:
1) Two O2 sensor holes are located wrong, such that the pre-cat one for the rear bank interferes with the nut that holds it on the exhaust manifold. I got it on and tight, but I'm afraid that it will be difficult/impossible to remove in the future. The O2 sensor in the post-cat location for the front bank was also located wrong and the sensor wire will not reach the connector when it's on the holder clip. I had to take the connector off and let it hang loose.
2) The flange to the extension pipe on the OEM part had tapped holes, but the flange on the Walker is not tapped. I had to come up with some nuts to make the connection.
3) There are no heat shields. Walker claims they are not needed.
4) A hanger rod is on the converter that is not needed and interferes with the transmission.
I checked the part number and it was the right one. It's just not done very well. I'm considering taking it back when I have a chance, due to manufacture's "defects".
Has anyone else replaced the converter with a direct fit? Any recommendations?
