CAT and DPF UnDelete

When I failed emissions this month, I discovered the 2009 Silverado 2500HD LMM that I bought from a small dealer in Phoenix earlier this year is missing it's CAT and DPF. When I called them to complain, they accused me of removing it and said they had a passing emissions report to prove it wasn't them. I know I didn't remove it and a thief surely wouldn't add a nice looking stainless delete kit with muffler

I am now faced with purchasing these parts and putting them back on. I suspect I will also need to purchase EFI to re-enable the RegGen cycle. I see the pig tails are tucked under it, so I don't think it will be too difficult, but what I don't know is what puts the diesel down the system during regen, is there some other part I need to look for or do the injectors just dump fuel during the exhaust stroke?

In 6 months, I am moving to a small town that doesn't require emissions testing, so I hope to put the delete kit back in it, but until then, I need to get my tags renewed.
