Sikky headers allow perfect drop-in fitment in the Mazda FD RX7 with a Sikky LSX Swap Kit.
All Sikky chassis specific swap headers are designed around using the Sikky mount kits and components. We cannot guarantee or confirm fitment when used in conjunction with a competitors product. Double check the required components section to see if anything else is needed for proper fitment. If you are unsure, contact one of our knowledgeable sales reps at firstname.lastname@example.org
