We have an over supply of exhaust headers for the LS series engines due to the fact that we had to have so many made to keep the individual cost down. The are mandrel bent in one section, except for 1 tube on each bank which has a tig joint. A couple of images of these headers are on my gallery.
There is a limited quanity available for $800-
pr plus freight. Let me know if you are interested.
Cheers,
Ian
