The description on the last one you posted stated it is made of T321 but then you scroll down to the pics and they say the flange and mandrel bent pipes are T304 ..........which is it ? I have cheap Ebay headers on mine made of T304 , been on the car four years and so far so good . Having said that if these headers shown below are REALLY T321 I would purchase them . But at that price I doubt they are T321 either that or they are made in a Chinese sweat shop
