I want to get Gibson Headers for my 2008 4.8l 1500 but the headers say without air induction and without EGR. Does that mean I have to supply the stock EGR or that these will only work with trucks without EGR and air induction. This is my first Chevy with fuel injection and computer controlled so I have no idea what they mean here.

 

There are headers that have smog hook ups.
