These are an older nos Hooker 2-1/8 race set I bought 4-5 years ago for a b-body project car I sold before moving to Tennessee. Ceramic coated, adjustable but the struts and primary tubes for lengthening didn't come with this set. Can't say how old they are but I can say it was before Hooker turned into crap mfg...these are very nice headers.

I predict future happiness for Americans if they can prevent the government from wasting the labors of the people under the pretense of taking care of them.
