§
TUBULAR EXHAUST SYSTEM: These components are designed as a system to improve the exhaust
efficiency of the 5.2L & 5.9L V8 engine. They are constructed of 409 HP stainless steel to better withstand
the high heat present with the fuel-injected engine, especially when used for towing or other heavy-duty
applications. The stainless steel used for these systems is much more durable than mild steel, although it
does not appear different in appearance. These systems come with a coat of black paint for protection
during shipping and storage.
components. Note that a magnet will stick to this type of stainless steel; magnetic attraction is not a valid
test for these systems. A performance gain can be expected by the installation of the system. This system
requires welding for installation and retains all O.E.M. emissions equipment.
§
SUGGESTED TOOLS FOR INSTALLATION: This vehicle has some metric fasteners.
ü 3/8" ratchet socket set with extensions and universal 13mm and 15mm swivel sockets
ü 12-point combination wrench set

§
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 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.
- High temperature spark plug wires and boots are recommended to withstand heat from T.E.S.
