SPECIAL NOTICE: This Edelbrock Tubular Exhaust System has received an Executive Order number (E.O.#) from the California Air Resources Board
(C.A.R.B.) making it legal for street use in all 50 states. To assist you with emission equipment certification, we 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.
WARNING: The use of "Thermal Wrap" or any aftermarket coating process will void the warranty
on your Edelbrock Tubular Exhaust Systems.
Those products can cause excessive heat and moisture buildup resulting in corrosion and failure of the system.
NOTE: High temperature spark plug wires and boots are recommended to withstand heat from T.E.S.
IMPORTANT NOTE:
Proper installation is the responsibility of the installer. Improper installation will void warranty and may result in poor
performance and engine or vehicle damage.
