What kind of EGR delete do you have? Did the up pipe get replaced or was it just blocked off with a plug?
I did not do the delete. It was that way when we got it. It looks like the pipe on the underside is new.
I do see a blue plate on the bottom of the EGR housing and a new tube
If the passenger side y pipe was replaced it should be ok. Sometimes these come loose at the exhaust manifold. Another thing is if the exhaust manifold bolts break you can get a whistle from them leaking.
