I finally today recieved the Racing Mazda Header, everything seemed to shipped right, it was all wrapped in bubble wrapp. First off let me tell you, i will never order anything again from Racing Mazda. First thing i noticed is that there are little knicks on the header. Another thing that really concerned me was, were the header bolts up to the block, the i guess you can say "runners" (holes) were filled with metal shavings that came off when they grinded down the header (the flat part that connects to the block). Lets not talk about welding, all i can say is gorrilla welds all over the place, and the bolt that they used to modify headers looks like it was used before, i thought it was suppose to be atleast shiny, mine is all black. I am very unhappy with this GB, as of right now i am taking offers for the header, so anybody that might be interested let me know.
