Seem to be worth between $200-$500 on Craigslist in my area (Missouri).
I agree F250 Marine and think it is wise to keep them....never know how or when laws will change. Also, if truck is under warranty, you would be wise to return to stock prior to visiting dealership. I will be removing mine this week for DPF delete and tuner install but will make sure I keep the original.
