I want to put a set of aftermarket headers on one of my cars but can't decide which route to go. Has anyone out there tried the Hooker Super Comp headers on a GN? The tech guy at Summit couldn't tell me much about them. I want to keep my stock turbo shield, stock waste gate, etc. I already bolted on a stock appearing 3" downpipe on a ported stock turbo elbow (T49). I'm trying to keep the engine compartment looking stock. The Poston headers look pretty cool, but I don't know much about them either. Then I saw a picture of the Hooker header system and was really impressed by how it looks. Has anyone tried any of headers, can they bolt right on without having to change or modify other components?
