360 precat inspection with bore scope

i have a snap-on bore scope and to me it looks like all I will need to do is remove the front oxygen sensor, insert the scope and look backwards. Sound right?

I guess that I will have to disconnect the wire/electric plug for the oxs prior to removal or the wires will get all twisted up.

 

Just got done. What I saw forward was just a metal mesh screen. Looked back and saw ?2 pipes coming together. So I am guessing the pre-cats sit behind that screen and then obviously cannot be seen through the front oxs hole.

Nice to know there is a screen there to prevent the larger cat fragments from being viciously sucked back into the motor as the sellers of replacement headers have suggested.

 

I should say, I looked back towards the rear of car and saw screen

At first I thought it was the cat. Same pattern but metal

 

I can picture take with scope. Geez gotta do again
