Need a pair of Thunder and Lightning/KE exhaust manifolds/headers.......had a sand blaster get a little overzealous in an area that cant be repaired

I always keep an eye open for these. Typically one pair will turn up every few years. Sometimes if you are really lucky two pair will be listed. If I were you, I would just call Diamond Performance and order a new set. It might cost you an extra $500 over what used sets bring and you will have them in a week and they will be new.

Call Bill @ Diamond perf. Any chance you just need one side? I had to replace just one header but had to buy the set, I think I have a spare but I forget which one it is.
