I have these longtube Hooker headers on my 01' Cobra (actually the black coated ones - got them installed about 3 years ago), and it appears Holly might be discontinuing/dumping these headers as they are really cheap. Roughly $375 for long tube ceramic coated headers is a steal, compared to their original $935 price.
