need help identifying the cats

[mista808]

as the title states, i need a little help identifying the cats in this picture for my car, 95 q45. question being i have an exhaust leak on the top of the pipe labeled in yellow, and i wanted to do a full custom exhaust from the cats all the way back... so are the cats the ones labeled in pink, or the ones labeled in green?

and for those that are interested in knowing, i was planning on going maybe 2.5" piping from the cats (which ever ones they are) in to an h-pipe, back to 2-single in/single out magnaflow or flowmaster mufflers, out the back to 2 chrome tips...

all help is greatly appreciated. just a simple answer is needed, no need to bash my thread. thanks in advance...

The pink ones are the main primary cats so you start your exhaust after them.

Green units are called precats which work primarily just after cranking until warm up [first 3-5 minutes].
