Default 2003 Ford Ranger 4.0 Exhaust Rework

I was going to completely redo the exhaust. Headers, cats, and muffler. Mainly because all of it is rusted to hell. My question, what do I exactly have under my truck? I know leading out from the headers I have the cats, but is that two more cats after that then muffler? What I do know is that I will replace headers with JBA headers. For cats I was hoping to do Spintech and also with the muffler. Then either having it turn down right before the back axle or out the side before the axle.

Wellll, the easiest way to tell is to take a peak under there. Today though I am feeling nice. 2003 4.0s had from the engine back....

manifolds
y-pipe(crossover pipe) with 2 cats
another cat
then your standard cat back exhaust.
