TUBULAR EXHAUST SYSTEM: These components are designed as a system to improve the exhaust efficiency of the
Chrysler 5.2L and 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 not require welding for installation and retains all O.E.M. emissions equipment.

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.
