EGR delete
So I plan on doing the EGR delete on the uppipe this weekend. At one point I found a great write up on an 03' delete (no scoop). Basically removed the uppipe. Cut off the y that goes to the EGR cooler, weld the uppipe back to function as a solid uppipe and plug and weld the y piece and replace both. I can't seem to find the write up. Does anyone know where I can find this? And if this is the correct instructions for deleting the EGR before the valve? Eventually I want to delete the cooler but i'm taking baby steps 
Thanks in advance.

You actually said what needs to be done. The only tricky part is to fit your hands behind the engine to remove the up pipe, and clamp on the EGR cooler. For that, I'd just drop the turbo down pipe, and you'll be comfortable...

This is actually the EGR cooler bypass.
-EGR delete: you completely get rid of the EGR cooler, you weld shot the up pipe ( after 04 remove the scoop from it ), and you replace the EGR cooler with a piece of pipe or hose, and block the EGR valve IN side usually with a plate.
EGR bypass: effective on 03, early 04 trucks with no restriction scoop in the up pipe. You place a plug ( freeze plug ) at the EGR cooler in side at the up pipe. Keep the EGR cooler in place, the coolant flow still there, but the hot exhaust gas can not get in to the EGR cooler chamber. Passes it ( bypass).
What he was mentioning is actually the bypass, but instead of a regular plug, he choose to cut a section ( Y ) out, so there is no connection between the exhaust and the EGR cooler.

so doing it this way means i dont need to buy any special kit? i just cut the egr cooler pipe and cap it off and cap the up-pipe off. just wondering because i saw the egr cooler bypass kits on ebay and they are like $150. since im doing the hpop i should just do this while i have everything apart right, and save myself 150 bucks?

I'm going to try briefly to not remove the downpipe but i doubt it can be done without removing it....That writeup showed it without a downpipe there, since he was doing exhaust upgrade in parallel
