Hello all, it is inspection time and I'm throwing the codes for catalytic converter and my vacuum switching valve (p0430, p0420, p0446). I have purchased the vacuum switching valve and I'm pretty sure it's the catalytic converter causing the other codes, pretty confident I've ruled out o2 sensors. When I was looking for cats I found the one below at a pretty good price, includes manifolds and cats, but am wondering if anyone has experience with these? My main concern is that I buy them and don't pass emissions. Thanks in advance.

I also saw these, but the quality did not seem as good based on pictures.
