Review on Walker 81767 CalCat Catalytic Converter by Adrian Retana

I had to do a two-year smog test in California. Strictly at the ZVEZDA station. My MIL light came on. It was giving out P420 codes and there was a rattling noise coming from the exhaust system and nothing could be seen. After 290,000 km of driving, one could assume that the torque converter would have to be replaced. I like to use official Honda OEM parts, but new factory parts start at $1,100 for parts alone, so I decided to look for them. I researched this and in fact this is listed on the California Air Resources Board website as approved for use on my 2002 Honda Accord 4 cylinder LX so I ordered it. I also ordered gaskets. It arrived quickly. I followed a tutorial video on YouTube titled "Changing the Catalytic Converter on a Honda Accord (2001)". The only difference is that I'm in California so I can't use the much cheaper option the guy used in the video. I also considered reusing the original nuts and bolts like the guy in the video because they were all fine, but unlike the guy in the video, the holes in my new converter's flange were too big for the bolts to fit properly could . No problem. I went to my local hardware store and bought six 30mm long, 10mm diameter, coarse thread stainless steel bolts and matching nuts and lock washers. I smeared some regular anti-seize permatex into all the nuts and the O2 sensor connector (not sure if it's O2 sensor approved or not so I just used a tiny dab). As in the video, this one comes with a whole new heat shield welded on, so I threw away the old one. All in all it was a lot easier than I expected. I've cleared the warning codes from my ECM and given it a couple of weeks to see if the MIL light comes back on and I'm going to take it to a smog station for the final test. Exhaust smells better.
