Will a 6.0 2004 run without a programmer if I cut this out

Are you talking about the CAT?

If you are talking about the catalytic converter, then yes. it will run fine. It will be louder. some have posted how they have picked up a few mpg's.

Like above assume you mean cat. Yes, a cat on a diesel just cuts down on noise and makes your exhaust smell like crap. There are no real benifits to a cat on a diesel motor.
