TUBULAR EXHAUST SYSTEM: These components are designed as a system to improve the exhaust efficiency of the
Dodge 5.7L Hemi 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 require welding for installation (see note below) and retains all O.E.M.
emissions equipment. Not designed for vehicles with solid front axle.
Suggested Tools Needed for Installation: This vehicle has some metric fasteners.
❑ Mig welder (recommended) or gas welder - Professional welding is highly recommended.
❑ 3/8” rachet, sockets, standard and deep SAE and metric & 13mm stubby combo wrench with extensions and
universal 13mm and 15mm swivel sockets
❑ Combination set of open-end wrenches
❑ Hacksaw or Sawzall
❑ Jackstands, screwdrivers, pliers, crescent wrench, etc.
❑ Liquid penetrant, (GM #1052627) and anti-seize compound (GM #5613695)
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 that 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.
IMPORTANT NOTE:
When cleaning any ceramic-coated Edelbrock T.E.S., use only soap and warm water. The use of caustic solvents (i.e.
gunks, etc.) will mar or damage the ceramic-coating.
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.
