i really need a diagram with how the egr system works i guess. from what i can see the only difference i can see with the greddy kit as opposed to other kits is the fact that it doesnt have an intercooler. so i was thinkin that maybe the way u have to pipe the intercooler affects how or where the egr goes in the exhaust. help me out here i dont have any idea what im talkin about.

somebody wanna explain how an egr works?
