Oh ok ok. Well, my turbo hadn't been off since I had the car, so whatever the factory setup was is how it was setup. I know the new turbo has an even larger supporting brace attached to it going to the head...it was one of the first things I noticed. I can't imagine how long this header leak has been present because now I'm aware of it, I've been hearing it for years. Could explain my shitty O2's in third?
