Top left is the converter, it's currently worth around $450-650 depending on part numbers on it. look for a 4-digit number and then 3 letters, like AAP, AAB, etc. Top right is the DPF, or diesel particulate filter. Again, depending on part number, it's worth from $50-$250. The part numbers on these pieces are stamped in in a dot-matrix style, can be a real pain in the butt to find. The part numbers are usually located down about 2-3" from the top on either side. The "top" being designated by where those little nibs are sticking up that have threaded bolt holes in them (they are for the diesel injection line brackets to bolt in to). So have the system sitting so those little bolt-hole towers are up top (in your current picture you can just see them sticking out on the bottom) and a few inches down from there, somewhere, will be those part numbers. The bottom piece is the foil/wire pre-converter, it's currently worth around $100. Don't throw any of that into your shred pile. Ever. That system there is currently the most valuable scrap converter being bought. Especially if it's 2008-2009, those are the most valuable.
