I have air suspension so was able to put it in OR2, no jack stands. I will say, if you have a creeper, well worth it for things like this! I would also find or build some sort of jig or stack a bunch of 2x4's to keep that muffler from falling down. It's not too heavy but when under the truck, you have almost no leverage and you definitely don't want it falling on your head! The hangers were the most difficult part to take off/put back on. Definitely over lubricate with WD40 or something to help with taking off the existing hangers and putting back on. I also had to cut the driver's side pipe to get it out since I wasn't lifting the truck up nor did I want to remove the spare and links. All-in-all, it took me a few hours to do alone while (basically) one armed due to an injury on my right shoulder. Get someone to help you and it should go much quicker!
