I have an old set of Hooker headers that came off my Dart a few years ago. I believe they are the competition headers. I did cut the flange at a young age to try to stop an exhaust leak. The bottom of the headers have seen the pavement a few times. They aren’t the best looking but if you need some cheap headers I’ll sell them for $100. Im in Cincinnati but travel around the tri state area a lot so for the right price I am open to meeting instead of shipping.
