egr?

did a search but nothing so is it worth 2 tune it out

Well if you remove it then yes.

will i see a differece in anything with it gone? im gussing i will cuz ur not dumping exshast gases back into the intake

I didnt notice anything when i removed mine.

well it will look better without it

Oh yea its a pretty ugly system. It really cleans it up a lot especially when you put LT'S on.

Get your self some lpp headers since i know they will fit a 2500.

thats what i was thinking plus they are a good price 4 lts

yea there super nice, ive had mine about 5 months and they still look great ,a little blue and gold. but thats just stainless.

for lots of info see

they claim no loss in performance and deleting it will hurt MPG.
