My 96 accord 4 cyl., 4 door, auto, and a/c, came from the state of California. So the exhaust system is different than Pennsylvania's as far as emissions go. If i replace the two cat converters to just one will that harm my engine in any way? One is $400 & the back is $300. I would like to avoid that expense should the need to replace one or both arise.

 

The car originally only came with one converter.

 

I was told I have two, by a Pa. Inspection station. A front & rear cat convertor

 

You can check the Honda service manual and Honda dealer parts sites. There isn't two converters on a 96.
