From what I understand, I ended up playing phone tag with the emissions rep but he said original OEM equipment. I found that listing as well, so I will most likely end up buying it and having it welded into my current delete pipe to make it play nice with my current exhaust.

You should ask the guys in the SD section that live in Colorado there's a few that can probably guide you in the right direction.
I would of thought as long it is carb certified shouldn't matter but what do I know I have no inspection in my state/county.

The emissions person is likely reading from a script. IIRC (and am not the best expert) the only acceptable cat is the one that was designed for the vehicle and even better performing parts from newer vehicles are not allowable (without CARB approval which requires a *lot* of money to get).
As z31 recommends, might want to find out exactly what happens during the emissions check from locals with actual experience. If it truly is a visual test, then the focus is on making sure that parts look like they are physically present and the truck does not blow smoke. Would not surprise me if it is the 'snap' test.
While not looking to add to the pile, might also want to find out about whether there is any attention to the intake housing during the emissions test. This is another area where I have read that folks in California complain about having to swap intakes just to pass inspection. In some cases, I have even seen people reinstall the OE turbo just to pass the test (OE called for a vacuum actuated wastegate and they had installed a turbo without wastegate).

A stock cat is on the way so this should suffice for the visual portion. I will need to unscrew my hydra selector and hide it away for the test as to not raise suspicion. I did talk with magnaflow and they stated that diesel CARB converters go straight to the dealerships.

The rep said the test consists of a loaded dyno from 40, 55, and 60 mph to conduct the opacity test. aside from that they check for the original emissions equipment and check to make sure the CEL light comes on and goes out/ stays out when the truck is running.

I told Eric I'll just get my wife to smog the truck. That should help it pass with flying colors.

Jake, are you going to gut the cat or put an actual one on there? In CA, mine was gutted. It was visual inspection only.

Plan is to put an actual cat back in. My original one had no issues at 230k miles, so this one should be good for the life of the truck. It should hopefully help reduce smoke for the opacity test. If EGT's become an issue I'll address it with a better turbo or tuning.

About to find out first hand this week if my '97 fairly stock 7.3L will pass CA Smog. It has a Riffraff intake, and aftermarket exhaust brake (disabled, for reasons still not clear to me), and aftermarket EGT that prying eyes might trip on. Everything I could find yesterday on CA gov't web sites says '97 and earlier diesels are exempt. Oh please, oh please, oh please. Don't want to spend a couple grand on the growing to-do list if this beast faces a major uphill climb to pass smog.

Registered the F350 today at DMV. No problems whatsoever. An hour total from start to finish, including VIN verification, new title, temp registration, basic plates, tags on the plates, and application for a personalized plate. The outgoing Washington title stated scale weight under 6k, and the door plate states 10k, so all good. Trailer will be titled, plated, etc., on a subsequent trip to DMV. Pleased that I stumbled into a smog exempt situation when I bought a '97, not knowing that smog requirements start in '98. The VIN verification tech looked under the hook for maybe 3min, then looked at her rear end for maybe 2min (good lookin' dually asset), and had little to say as he filled out his form. Engine never ran during the exam. The key appears to be 1997 or earlier.
