    Ummmmmm, reading comprehension and search function!

    Theyre speed daddy's

    Cheap headers that many use, requires some tweaking for fitting.

    Best headers (available) but expensive - ZZP Stainless. Pick your poison...

    I have ceramic coated pace setters, best IMO, lolz : )

    If you are going to buy speed daddy's , buy them directly from the speed daddy website. I did and had zero issues installing them . Even the flex (the part that most complain about ) was double walled not single like alot of people have been talking about with previous versions. Mine went together smoothly with exception of the old 220k mile old parts lol. If i can give you any advice it's this, don't tighten the headers up until you have all connections made for the crossover section. They are a great deal and seem very well made .

    No gold, it comes with a downpipe. You cant use like a ZZP Downpipe with them but you have to have a downpipe...

    SD headers are great. Ran them for 2-3 years with a 2.8 pulley setup, now my buddy has em on his 3.4 setup (I went turbo). Great headers though they do require some TLC with a hammer to fit sometimes.
