#___" space. THANK YOU.
• TUBULAR EXHAUST SYSTEM: These components are designed as a system to improve the exhaust efficiency of the Jeep 5.2 Liter 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 can be identified by the part numbers on each of the major 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 does not require welding for installation and retains all O.E.M. emissions equipment.
• SUGGESTED TOOLS FOR INSTALLATION: This vehicle has some metric fasteners.
❑ 3/8" ratchet socket set with extensions and
universal 13mm and 15mm swivel sockets
❑ Combination set of open-end wrenches
❑ Hack saw
• 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.
• NOTE: High temperature spark plug wires and boots are recommended to withstand heat from T.E.S.
Proper installation is the responsibility of the installer. Improper installation will void warranty and may result in poor performance
