06 civic catback
 

I recently ordered and exhaust system and was looking at a few videos but could find an instillation video for my car, only the si, so my question is do I have a cat under the body of my car or is the one under the hood the only one I have

I am trying to put this as gently as possible...

Look under your car/hood and see where the cat is. If you cannot do that, then you should hire someone else to install it.

I know where my cat is...my question was do I have two? Because I was doing some research and people were talking about sensors in their cats and as far as I know I don't have a sensor.

On an 06 R engine the cat is hanging on the front of the engine. That's the only cat.
You have two O2 sensors, one above the cat and the other below the cat.

Thank you,

What do the sensors look like and should I remove them before installing the cat back

You should not have to touch the sensors at all.
