TUBULAR EXHAUST SYSTEM: This stainless steel Tubular Exhaust System header is designed to improve the exhaust
efficiency of the Toyota 3.4L V6 engine. A performance gain can be expected by the installation of the system. This
system does require welding for installation (see note below) and retains all O.E.M. emissions equipment. These
Tubular Exhaust Systems are street legal in all 50 states.

K Mig welder (recommended) or gas welder - Professional welding is highly recommended.

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.
CAUTION: Due to higher underhood temperatures generated by TES, vehicles equipped with original spark plug wires
should have them replaced with high temperature plug wires for longer life.
NOTES:
1. The paint used on non-coated T.E.S. is for protection during shipping and storage and will burn off soon after the
engine is started. Those who desire a longer lasting finish should sandblast the T.E.S. to remove the original paint,
then apply high temperature header paint, such as VHT, available at most auto parts stores.
2. When cleaning any Edelbrock Pro-Tech coated TES, use only soap and warm water. The use of caustic solvents
(gunk, etc.) will mar or damage the Pro-Tech coating.
3. High temperature spark plug wires and boots are recommended to withstand heat from T.E.S.
