TUBULAR EXHAUST SYSTEM: These components are designed as a system to improve the exhaust efficiency of the

Dodge 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 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.

❑ 

Mig welder (recommended) or gas welder - Professional welding is highly recommended.

❑

3/8” rachet socket with extensions and universal 13mm and 15mm swivel sockets

❑ 

Combination set of open-end wrenches

❑ 

Hacksaw

❑ 

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.  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.

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

4. When installing this system on a truck equipped with a standard transmission, it may be necessary to do some

grinding on aluminum bellhousing.  The first area is where the left side collector flange is.  The other area is where

the left crossover pipe goes under the bellhousing.  Only minor grinding may be needed to obtain better clerance

in these areas.
