F. I. A. Legal E-Type Header. These are made specifically to the requirements of the F. I. A. international sanctioning body. To satisfy the regulations the header cannot cross over the frame tubes. Utilizing a full 2 diameter primary, these beautifully made stainless steel headers fit within the stock frame and offer you the option of fabricating a straight-through racing tail pipe on your own, or attach to the stock pipes for street use. Special Order. This photo shows the F. I. A. stainless steel system after a season of racing. The bronzing, of the tubing is to be expected as the stainless steel headers heat-cycle.
