yes, the 2nd cat its robbing power from the engine but the question is would removing it increase the STOCK (already robbed) HP?

Removing the second cat won't give you any noticable gains. It isn't really all that restrictive as it is, plus your car may not pass emissions testing.

Can someone set me straight. I was under the impression (like Protegé Menacé) that there's a cat., a resonator, and a muffler.
Whats this about two Cats?

Read the FAQ.

It depends on the model year of your car.
