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.
