SPECIAL NOTICE: This Edelbrock Tubular Exhaust System has received an Executive Order number (E.O.#) from the California Air

have included a silver fan shroud decal to help testing personnel verify the this part is a legal replacement on the vehicle for which
it is cataloged. The adhesive-backed decal should be affixed next to the existing emission and engine specifications decal. Do not
cover any part of your original emission decal.
