Your talking about headers made from two different companys. I understand all that but I bought the same exact springs hes selling for a lower price. Its not like I bought a knock off or anything. I would buy it from throwdown if he made them but he didnt hes just buying parts already made and slinging them for a lil more money. Will I see anything custom from him 99% no. I myself have been working on a cheap turbo kit for everyone for the past 3 months that bolts to the stock header and the turbo sits where the stock cat is. I have to brush it aside for now because my aveo ticks pretty bad when facing down hill or hard breaking. But anyways im just hijacking a thread I will stop my rant.
