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 come with a coat of black paint or ceramic coating for good looks and
protection during shipping and storage, and they 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.
Suggested Tools Needed for Installation: This vehicle has some metric fasteners.
K Mig welder (recommended) or gas welder - Professional welding is highly recommended.
K 3/8" rachet, sockets, standard and deep SAE and metric & 13mm stubby combo wrench with extensions and universal 13mm
and 15mm swivel sockets
K Combination set of open-end wrenches
K Hacksaw or Sawzall
K Jackstands, screwdrivers, pliers, crescent wrench, etc.
K 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. No additional
thermal isolation is required, as T.E.S. are Pro Tech-coated for corrosion resistance and long life.
IMPORTANT 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 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.
2. When cleaning any Edelbrock Pro Tech-coated T.E.S., use only soap and warm water. The use of caustic solvents (i.e. gunks, etc.)
will mar or damage the Pro-Tech coating.
DISASSEMBLY
1. Disconnect negative battery cable.
2. Raise and support truck with two post car hoist
(recommended) or jackstands and remove both front
wheels.
3. Remove both left and right inner fender wells and set aside.
4. Disconnect and remove O2 sensor from the front of catalytic
converter, being careful not to damage.

by measuring up to floor plan and out from frame rail for
installation of the exhaust pipe.
6. Cut exhaust pipe off from catalytic converter right at the
weld.
7. Unbolt and remove exhaust pipe from stock manifolds.
