(Subaru) Intermittent Starting Problem - Mechanics "Have No Idea"

If the catalytic converter were restricted to the point that the engine were difficult to start there wouldn’t be enough engine power to drive the vehicle. Does your engine lack in performance?

According to the mechanics I’ve taken it to, no. It starts most of the time, and once it has started, it runs really well.

The code for the catalytic converter is a symptom of the issue. The fact that it runs really well once started shows the cat is not restricting exhaust flow.
