TA's seem to be the choice. I haven't tried them but they are on the new list of parts. There is a thread on the fitment issues. Maybe someone will respond to this.
9's is where im at.. and i got car not to long ago.. i poped a head gasket, my motor guy calls me last night and asks where i got the headers.. told him they came on the car.. he says they look like ebay headers adn are cracking ... so thats why ..
You really need a bigger primary tube header if youre going that fast. We've made some sets, they do make more power on the dyno but they're not cheap as they're custom.
