    If it only has one then they are the wrong ones but you can take the egr off and get a LS1 tone all you well need is a 1 3/8 plug for the intake

    the plug you can get at AZ or O'rielly's... the other flanges are for the AIR system.. Delete if you want, you can turn off the codes it will throw for EGR, and AIR with a tune.
