Thanks SMJ - I was thinking about the same thing. Replacing just the one that definitely failed. I may run it by another shop just to get the error code reading confirmed.smj999smj wrote:I would only replace the converter that failed along with the upstream oxygen sensor on that particular bank. I've used Walker catalytic converters and I haven't had any issues with them so far. The genuine Nissan converters are ridiculously expensive!

Then, my left bank started triggering a P0430 catalyst code intermittently at 170,000 miles, which I haven't gotten around to changing, yet, now at 182,000 miles (and now triggering the code more frequently). Ironically, my 2008 Pathfinder V6 has 233,000 miles on it and the entire exhaust, including all of the converters, are all original and not triggering any codes (knock on wood!). The only thing I ever replaced on the exhaust on the 2008 is a few heat shield straps that rusted and broke.
How hard is it to change out?smj999smj wrote:The left bank was replaced by Nissan under extended warranty at 84,000 miles. I replaced the right bank with a Walker converter at 155,000 miles.
