Over $6000 to install TTI headers on 66 Barracuda

OK everybody chill. Yes 6k is an outrageous number. The tech knows that too. Why is he asking that much? What all went into that 60 he's of work? There is more to this story than you (the op) is telling us I know some shops will sometimes try to squeak a few hours here and there by a costumer but at this level? There is something else to the puzzle. We need more details. A shop that can get 60$ an hour labor rate is probably a higher end shop
