Anyone out here ever try a set of blackjack headers? I had them on a jeep p/u a few years back (13) yrs ago and they worked fine. Are they still available? Are they worth the money?

In my opinion, the "Thermal Barrier Coated Headers" Hooker Headers, Competition searies are the best for the money. Alittle spendy, but lifetime warrenty. Just under $500.00
