Craigslist add anyone know what headers these are?

My concern would be the underhood heat. I do have a cold air intake from outside but, I bet it gets pretty hot under there. Just thought it was kinda cool to see something different and something I haven't seen done before. I'm sure they are better than the stock manifolds. Maybe Ill give him a call and see if I can get any info.

ya let us know what he says. i really like the idea. if you were to have them coated in and out or wrapped i dont think it would matter much. it would be even better if you had a scoop shoving air down there.
