does removal of the def tank required dropping the fuel tank as well? IMO, dropping fuel tank is a huge PITA everytime ive had to do it on other vehicles but if its more straightforward than that, that seems like a better option... bea helluva lot of work to reinstal the def tank & dpf to make a dealer trip though.... and then re-remove all of it when you get it back, and so on...

do the exhaust come with any fittings, instructions, or whatever needed to either remove or plug off all the urea stuff?
