I give up! I've been going back and forth between forums, pics, and my engine bay and I can't decide if my headers are stock or not. I think they are, because they look pretty restrictive. On the other hand, the connections from cylinders 3 and 5 (the only ones I can see easily) aren't straight pipes making a 90 degree connection with the main pipe, they're slanted like cylinder 2's connection. Theres my dilemma, cause I'm wondering if they're just cheap aftermarket headers (they came with the car).
