catalytic converter assembly. NOTE: The small A.I.R. tube connection
should be a slip joint, however, the factory clamp is usually over-

from a torch to help loosen it.

• TUBULAR EXHAUST SYSTEM:These components are designed as a system to improve the exhaust efficiency of the GM T.P. I. (tuned port injection)
V8 engine. A performance gain can be expected by the installation of the system. This system does require welding for installation and retains
all O.E.M. emissions equipment.
• SUGGESTED TOOLS FOR INSTALLATION: This vehicle has some metric fasteners
— MIG welder (recommended) or gas welder. Professional welding is highly recommended.
— 3/8” ratchet socket set with extensions and universal 13mm and 15mm swivel socketsI
— Combination set of open-end wrenches
— Jackstands, screwdrivers, pliers, crescent wrench, hacksaw, etc.
— Liquid penetrant, (GM #1052627) anti-seize compound (GM #5613695)
— Spark plug wire crimping tool
• SPECIAL NOTICE: This Edelbrock part has received an Executive Order number (E.O. #) from the California Air Resources Board (C.A.R.B.) making
it legal for street use on pollution-controlled motor vehicles in all 50 states.To assist you with emissions equipment certification, we have included
a silver fan shroud decal to verify that this part is a legal replacement part on the vehicle for which it is cataloged. The adhesive-backed decal
should be affixed to your fan shroud next to the existing emission and engine specification decal. Do not cover your original equipment specification
decal with the Edelbrock fan shroud decal.
• WARNING: The use of “Thermal Wrap” or any aftermarket coating process will void the warranty on your Tubular Exhaust System. Those products
can cause excessive heat and moisture buildup resulting in corrosion and early failure of the system.
• NOTES: 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 sand blast the T.E.S. to remove the original paint, then apply high temperature header paint, such as VHT,
available at most auto parts stores.
• 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.
• High temperature spark plug wires and boots are recommended to withstand heat from T.E.S.
