Disassembly - Left Side
1. Disconnect negative cable from battery.
2. Use penetrating oil on all nuts and bolts to be removed.
This will prevent the possibility of broken or stripped nuts
and bolts.
3. Disconnect spark plug wires and spark plugs.
4. Disconnect temperature sensor wire.
5. Remove bolts and exhaust manifold.
Disassembly - Right Side
1. Remove air cleaner box. Note all hose and electrical
connection.
2. Disconnect spark plug wires and spark plugs.
3. Remove dipstick and dipstick tube.
4. Remove bolts and exhaust manifold.
5. Clean exhaust flange surfaces on both cylinder heads at
this time.
DISASSEMBLY - CROSSOVER PIPE
1. Raise vehicle and support with jackstands.
2. Disconnect and remove 02 sensors (2), being careful not
to rupture or destroy the unit.
WARNING: Do not clean this unit in any cleaning solvent
and do not damage wire.
3. Cut left OEM crossover pipe 3/4" left of the weld on the
catalytic converter. This is the catalytic converter located
under the transmission. Cut the right OEM head pipe
3/4" in front of the weld attaching the right catalytic
converter. Remove exhaust pipes from vehicle.
NOTE: Before cutting pipes, measure the height of the
converter from the bottom of the floor board for when you
install new exhaust pipes you can maintain same
distance.
• ASSEMBLY - LEFT SIDE
1. Install T.E.S. flange gasket and one 3/8"-16 x 1" bolt, lock
washer, and thick flat washer at rearmost bolt hole (leave
bolt loose enough to accept T.E.S.).
2. Install left side T.E.S. manifold from bottom side.
3. Install all bolts and washers and tighten. Use thick flat
washers on slotted holes.

4. Re-install spark plugs.
5. Replace original equipment spark plug wires on cylinders
#3 and #5 with supplied wires. Re-connect spark plug
wires on left side.
6. Re-install temperature sensor wire to temperature sensor.
ASSEMBLY - RIGHT SIDE
1. Install T.E.S. flange gasket and one 3/8"-16 x 1" bolt, lock
washer and thick flat washers at rearmost bolt hole (leave
bolt loose enough to accept T.E.S.).
2. Install right side T.E.S. manifold from top side. Now install
dipstick tube.
3. Install remaining bolts and lock washers.
4. Align all parts and tighten all right side bolts at this time.
5. Replace original equipment spark plug wires on cylinders
#4, #6 and #8 with supplied wires. Re-connect right side
spark plug wires.
6. To prevent contact with the hot T.E.S. tubing, use nylon tie
wrap (supplied) to secure the heater hose to the a.c. dryer.
7. Re-install air cleaner box.
CROSSOVER PIPE ASSEMBLY
1. With catalytic converters in their natural position, install
and bolt exhaust extension pipes to header collectors
using 3/8" - 16" x 2 1/2" hex bolts, 3/8" flat washers,
3/8" lock washers and 3/8 hex nuts. Use the 3" donut
provided in kit.
2. Check alignment of pipes to the catalytic converter,
secure bolts.
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.
8. Start vehicle and check for leaks.
9. After engine has cooled, re-torque the header flange bolts
from center of flange out.
