I have limited knowledge of the 6.0L so any feedback would be greatly appreciated.
FORD 6.0 6.0L 2003-07 EGR DELETE KIT F250-F450 POWERSTROKE SUPERDUTY | eBay
That is the same kit I installed on my truck. It works just fine.

I know a lot of people do it but isn't it a vital part of the motor? where does the coolant or exhaust gas go if you get rid of the egr? Does it help fuel milage or hurt it. I guess i am wondering what the benefits are to getting rid of it versus replacing it.
The EGR is not a vital part of the motor. It is a pollution control device.
The egr cooler is actually what is being deleted. The EGR cooler cools exhaust gases before they are reintroduced into the cylinders. The design of the stock EGR cooler is fairly weak, along with the way that the EGR cooler gets the coolant that it uses to cool the exhaust gases.
The typical scenario:
The stock Ford coolant is also garbage. The chemical additives in it deplete rapidly and you never hear of anyone that actually does the required testing of the coolant to maintain the additives. Left ignored, the additives drop to low levels and corrosion begins. Also, when the level of additives is low the coolant can no longer deal with high heat (especially in the egr cooler which can see 1000°F fairly regularly). The coolant breaks down and this causes gunk to form along with rust scale. This junk flows along with the coolant. The design of the oil cooler has both liquids (oil and coolant) entering and exiting the top. Any solids or contaminants will settle to the bottom. This will cause a clog to form in the lower portion of the oil cooler on the coolant side. This clog will continue to grow as long as the same coolant is in the engine. When the clog gets big enough, it will slow the coolant flow through the oil cooler. The coolant that leaves the oil cooler is directly fed to the EGR cooler. Since the coolant is now moving slower, the egr cooler overheats and eventually, it fails. The coolant will flow out of the failed EGR cooler and when the EGR valve is commanded open, coolant will then flow into the cylinders. This will raise the cylinder pressures beyond what the stock head bolts can withstand, and that stretches the head bolts. The stretched head bolts allow the heads to lift and this is how the head gaskets gets popped.
Your question about where the exhaust gases go:
Well, when you delete the EGR cooler, the kit comes with a new up-pipe. This deletes the connecting point for the EGR cooler. The exhaust no longer gets circulated back into the intake (as a percentage) it goes out the tailpipe.
The EGR cooler delete kits come with another pipe (U or J shaped) that redirects the coolant flow from the oil cooler back to the waterpump via the same connection to the intake manifold that the EGR cooler used.
Fuel mileage will not be effected very much at all. If anything, you may lose some.
The benefits of installing an egr cooler delete are:
Cleaner intake tract
Less of a chance of blowing the head gaskets (it can't fail if it isn't there)
One less thing to go wrong
