It's a PITA. I'm currently doing it myself when I have time on weekends etc. The front bank isn't too bad. The rear is a beeotch but alot of exstentions and half the studs are easy to get at. The EGR tube can be a pain( I had to cut mine off) As for install I have no clue i haven't got there yet....crappy weather and no time between 2 jobs

This weekend I'm hoping to get them in.
