INSTALLATION INSTRUCTIONS

Please study these instructions carefully before installing your new

Tubular Exhaust System

(TES). If you have any questions, please

contact our Technical Hotline at : 1-800-416-8628 from 7 am - 5pm, Monday-Friday, Pacific Standard Time or e-mail us at

[email protected].

TUBULAR EXHAUST SYSTEM: These components are designed to improve the exhaust efficiency of the GM C.P.I. (Central Port

Injection) V8 engine. A performance gain can be expected by the installation of the system. This system does require welding

for installation and retains all O.E.M. emissions equipment.

Suggested Tools Needed for Installation: This vehicle has metric fasteners.

❑Mig welder (recommended) or gas welder—Professional welding is highly recommended

❑ 3/8” ratchet socket set with extensions and universal 13mm and 15mm swivel sockets

❑Combination set of open-end wrenches

❑ Jackstands, screwdrivers, pliers, crescent wrench, etc.

❑Hacksaw or Sawz-all

❑Liquid penetrant, (GM #1052627) 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 the 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.

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

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.

• DISASSEMBLY

1. Disconnect negative battery cable.

2. Disconnect and remove both left and right 02 sensors.

3. Unbolt the exhaust hanger/transmission heat shield

assembly from transmission.

4. Disconnect both left and right exhaust pipes from stock

manifolds and allow pipes to hang.

5. With a sawzall, cut left side pipe directly in the middle of the

straight between bends right under bell housing,

(See Fig.

6. Cut right side exhaust pipe directly in the middle of the

straight between bends,

(See Fig. 2)

• RIGHT SIDE

1. Disconnect and remove spark plug wires.

2. Disconnect E.G.R. flange.

3. Unbolt dipstick tube.

4. Unbolt and remove manifold.

5. Install T.E.S. flange gasket and TES manifold from top.

Install header bolts supplied and leave loose enough to

ensure proper alignment.

NOTE: Use flat washers and lock washers on all bolts.

6. Install E.G.R. flange using supplied gaskets, bolts and lock

washers.

7. Re-install spark plug wires.

8. Re-fasten dipstick tube.

INSTALLATION INSTRUCTIONS

• LEFT SIDE

1. Disconnect and remove spark plug wires.

2. Unbolt and remove manifold.

3. Install T.E.S. flange gasket and T.E.S. manifold from top.

Install header bolts supplied to ensure proper alignment and

tighten bolts.

4. Re-install spark plug wires.

• CROSSOVER PIPE ASSEMBLY

1. With exhaust hanger/transmission heat shield assembly

bolted back on transmission holding the exhaust pipes in

their natural position, install and bolt exhaust pipes to

headers using 3/8" x 16 x 2-1/2" hex bolts, 3/8" flat

washers, 3/8" lockwashers and 3/8" hex nuts. Use the 3"

donut provided in kit.

2. Check alignment of pipes to the catalytic converter, secure

bolts,

(See Fig. 3).

3. With everything in place, tack weld exhaust pipes to

catalytic assembly.

4. Unbolt whole exhaust assembly from vehicle and let it hang.

Complete weld around pipes.

5. Bolt assembly back in vehicle and check for clearance.

6. Re-install 02 sensors. Use anti-seize on threads of sensor.

Route wires clear of exhaust system.

7. Lower vehicle to ground.

• FINAL INSPECTION

1. Check all lines (hydraulic, vacuum, air conditioning and fuel)

to ensure there is adequate clearance to T.E.S. components.

2. Re-connect battery.

3. At this point it is a good idea to look everything over and

make sure that nothing was missed in assembly.

4. Start vehicle and bring up to normal operating temperature.

Check for possible leaks.

5. Turn engine off and let cool. Tighten all bolts again.

• CAUTION: Before operating your vehicle, check to ensure

that there is adequate clearance between all parts of your

TES (including A.I.R. tubes) and all brake lines, fuel lines,

spark plug wires, etc.
