I have a custom set of headers that were made for an 88-98 C1500 that exits outside of the frame. I didn't use them because I'm going to run mufflers. Would have to modify the front cab mounts or cut the collectors back a few inches since the truck they were made for moved the body mounts inboard. They are in good shape but not new. All I would do is cut the collectors back and install turndowns for a race only truck. They are coated and have EGT bungs installed currently with threaded plugs. 2.25” primaries with 4” collectors. I have more pictures I can send. Best way to contact me is email [email protected] due to working offshore.
