Man that sucks on the bumper, F'in low life could have atleast left a note .. But on a good note, my 07 did the same thing pretty much and I did just the egr cooler at the time couldn't do the whole job as it was Just right after Id bought the truck .. But it turned out ok, hg held up and ended up running a sct with custom tunes, same exhaust you have and s&b intake an they still head up good! Maybe I just got lucky but it had way more miles than yours too like 211k .. So don't worry too much, hell I was in same boat Hopeing like Hell I wasnt gonna have to take it all back right back apart lol!
