Many mechanics seem to be given different answers. Some say one other day two and I am not sure what to do.
Thanks.

Good afternoon,

You have two catalytic converter. One on each exhaust manifold. One is in the front and one in the rear.

I attached a link to rock auto who has them but lists them as left and right.

Thank you for answering my initial questions about the number of catalytic converters in my car. I appreciate it.
Secondly, I want to know which one is bank 1 and 2 is bank one the one close to the radiator? And in total how many 02 sensors does the car have?
Thank you so much.

The firewall side is bank 1.

You should have 4 sensors. 2 upstream and 2 downstream.

Good Afternoon Roy,

Thank you for everything I saw the images but it said "non mivec" does it change anything because my engine is mivec.
I also looked underneath my car and saw something like a catalytic converter then the resonator pipe which is very confusing because that would mean 3 catalytic converters if that is not a cat what is that?
I would also want to bring my car to your shop if you have one and it is not too far from me. I live in Rockland county NY or if you can refer me to a good place to go.
You have been super helpful.
Thank you

You are welcome.

No, I live in central PA. I do not have any connections with that area, sorry.

Does not make a difference.

Hey Roy,

Is there a database of which cars have multiple Catalytic Converters?

Thanks,

No, there is no database for just that.

You need an information system such as Alldata or Mitchel on demand that can bring up each car and show you the converters.
