Is it true that some Hondas have their cat converter inside their header? Which models?

 

My old d16y7 had a two piece cat, one before the collector and the 2nd after...

 

Well I'm new to learning about my Honda, but my Civics cat converter is attached to the manifold in the front of the car then goes down to the exhaust. I always thought the cat converter was a little muffler next to the regular size muffler. Live and learn.
