    Ceramic Coated Big Block Headers for Sidepipes

     $695.00
    Ceramic Coated Big Block Headers for Sidepipes! I could not find anyone that makes sidepipe headers for a big block for any year Corvette, so I now have these here at McJacks. This header system works great for all year Big Block Corvette with sidepipes from 1963 - 1982. These headers fit nicely around your factory steering box, Corvettes with Air Conditioning, and easily misses the frame. Perfect for Corvettes with Sidepipes.
