Like the man said, not too hard but getting more expensive by the day. Both Edge and H&S have quit making tuners that you can use to delete. So, if you want one of thm you have to find one in a speed shop or on aa craigs list somewhere. As far as I know Spartan is still in business. I don't know why but given our current government I can guess. You need the delete pipe and a tuner. Easy way is to remove both the DOC (cat) and the DPF. You can check ebay, just go to motors/parts/dpf delete and the stuff will come up if there is any left. Good luck. Oh yeah, one more thing, it's a violation of federal law. just kiddin man. You won't regret it, the truck runs way different.
