it has the 5.7 hemi adjustable track Bar what is that lol2500's have different suspension. You can put Bilsteins shocks on it but they aren't going to level the truck. For that you need either taller front coils or leveling spacers. You'll want to put longer shocks on at the same time to maintain the ride quality. Depending on how much you lift the front you'll probably want an adjustable track bar too.
As far as exhaust goes, does your truck have a hemi or Cummins?
