I have an '08 Dodge that's partially deleted - DPF only. I bought it used from a dealer and they didn't tell me. They likely didn't know it themselves. It took a while before I figured it out. There's a flashing chip under the dash that clued me in. I got a name and number off of it and found it on the web. It resets the computer every time I start it.
That said - in 10 years I've never had to worry about a burn off but it does blow smoke. It runs pretty dirty and leaves a lot of soot on one side of the bumper.
There are only a couple counties in ID that do emissions testing and I'm not in one of them.
