6.0 Was the last engine before the feds strangled them with heavy emissions equipment like the 6.4 and especially the 6.7. Like Bullit said no sensors or lights at all.
Straight piping a 6.0 is a good thing for it, going to be louder than stock for sure but not bad. I like the sound of it, your truck will have a unique sound unlike any stock diesel truck. People will know it's you without looking after they hear the sound of the turbo whine and deep note.
Backpressure is lower, there are no negatives to straight piping exept for the noise level is higher. Lower exhaust temps are worth it.
Will straight piping effect the smog/emissions? I live in the peoples republic of California.

I live in the same repressive state as you and mine passed smog a few months ago, I do have a cat on the truck but it is a empty can and they just looked to see it was there.
You don't need a muffler to pass smog just the cat, you can buy the sleeves for welding the 4" onto the cat and then clamp it on it's up to you if you want to keep it intact or clear it out. The turbo whine is real clear when it's wide open and a full flowing exhaust.
Infantryman is correct just make sure the egr is intact they were pretty thorough looking at that, just glanced at the cat convertor.
