I can’t relate specifics. I do know eBay car parts can be pretty dodgy lately so buyer beware . I’d make sure it’s from someone reputable rather than the lesser known sorts. There’s a lot that can go wrong if they use junk recycled internals and you’d have no way to know till you went to the hassle of installing it all. Just my my nickels worth 🫣

 

You'll get what you pay for. Cheap convertors have thin coating of precious metals. This will only last 20-40k vs 100k+ of a quality convertor.

I would change your downstream o2 sensor first. it is less expensive than the cat and easier to change (more likely to go out). On my 04 4runner I put o2 spacers on the downstream sensors (pulls the o2 sensor out of the exhaust stream) and have never had a code again. I was getting them pretty regularly because of a head gasket leak that was burning antifreeze and ruining the cat. I don't live in an inspection state, so no worries about that.
