Ask the seller
most cats do not include any sensors. they will just give you the cat as well as documentation depending on if its a carb cat iirc they have to give you the certificate of approval from california.
I’m pretty sure no but I think they’re sold at auto part stores
I figured, so i have to but separate then? Both the cat n the o2 sensor?
Wdym separate
Likely purchase them separate yes
So no cat and o2 sensors?
Get yourself GM sensors, you dont want unknown brands..
He just like me fr catless and no sensors
I need to stop being lazy it’s making my car run rough
Cat and o2 sensors are sold separately in most cases. That said, you might not need both or all. What are you experiencing that has you going down this path?
For emission test
He said there's something wrong
The downstream o2 sensors monitor emissions
Upstream is air fuel ratio
