Get rid of the factory closed box air filter setup and get either a Tymar or a DIY intake. The more air you can draw in will help lower EGT's.
Also, gut the cat before you put the exhaust on. They have no way of telling if a cat is gutted or not. I don't think a diesel has the same laws for removing a cat as a gas vehicle. I think it is ok to remove one.
With a gutted or no cat, the EGT's will be lower as well.
