Red face Catalytic Converter

So I have 484512 miles on 04 rx330 and been get the codes for catalyst low can’t remember code numbers. Now I’ve look into the new catalytic converter manifold and they are out of my budget. So while search amazon found they adapters for the o2 sensors with a small catalyst in it , supposed to stop the code from back, so I bought a pair that where 90 degree angle to make sure I had clearance. Installed them and dam if they didn’t actually work normally in just couple miles my check engine light would come on, but drove around own made couple stop and more check engine light. Ok this ended up sounding like a infomercial but if your having same issue it’s cheap enough to try (see attached link). And FYI if you have emission testing in your this will in no way help you pass.

yes I have the cheapest was on eBay for around $200 but if you look at the pictures they looked as if a 2 year old made them and pipe fitment was so bad looking it would reduce air flow

and these adapters where not my first choice it was my last choice but dam they work

Not for sale in California. I believe this part is so expensive because they and them want to get us out of gas cars.
