Loud rattle after EGR / DPF delete install

Hi all, so I took on the task of doing an EGR Delete / DPF delete on my 2008 F250 6.4L. The install went smooth, well it took longer than expected but for the most part it wasn't too terribly bad. But after filling up the coolant and checking all hoses and made sure there were no leaks or anything not disconnected, I finally cranked her up. Ok heres where the problem started, upon firing her up a loud mettle on mettle sound starts to clunk and gets louder when the truck is at full idle from what sounds like near the turbos. Ive looked at every inch of the motor to figure out where it could be coming from, no trouble codes, nothing is leaking, nothing is over heating or smells out of the ordinary. I cant find what is making the sound, it DOES sound like its coming from in the turbo housing (i think) but the EGR delete I installed doesnt havent anything to do with the oil lines or anything going to the turbos so I am kind of confused what it could be. I am afraid to drive it any wheres or even leave it cranked for more than 10-20secs because the noise is so loud. Anyone have any tips or ideas what it could be? At this point I am kind of clueless, any help would be very much appreciated, thanks in advance to anyone!

Is there a chance you drop something in anything?

I hope not, but I could be wrong. That was my first impression, but I looked in the engine bay and even had a second and third pair of eyes and we could find the source or anything touching or rubbing together, or any tools that might of been left behind :/

When I removed my EGR, the up pipe that fed the lower cooler wasn't bolted down on the bottom. There's a little tab on the back of the pipe that bolts to something (I can't remember what), and it was rattling. Well, it rattled until I removed the pipe entirely and relocated my EBP sensor.

Anyway, I'd check that pipe for rattles, since that was a problem on mine.

Thanks for the tip! But I finally found the problem and it was close to where you mentioned. I removed the bracket that held the lower EGR Cooler in place and I didnt realize those bolts had to go back in. They were the ones that connected the lower manifold to the engine lol. So that ended up being the loud noise, thank god it was something easy and nothing that was internal based. Thanks everyone for the help!
