• DISASSEMBLY
1. Disconnect negative battery cable.
2. Raise vehicle and unplug both O2 sensor cables.
3. Starting with the driver's side, remove the three bolts on
the inlet flange on the catalytic converter.
4. At midsection of left side exhaust pipe is a two-bolt
flange; unbolt and set catalytic converter aside.
5. On passenger's side, remove the three bolts at the
manifold/exhaust pipe connection.
6. A two-bolt catalytic converter hanger assembly is at mid-
car; remove bolts and separate catalytic from hanger.
7. At mid-intermediate-pipe is a slip fit connection. Loosen
U-clamp and separate intermediate-pipe from the
catalytic pipe. Now remove the whole unit from beneath
and set aside.
• LEFT SIDE
1. Disconnect and remove spark plug wires.
2. Disconnect A.I.R. assembly from stock manifold.
3. Remove 02 sensor from stock manifold (be sure not to
break or damage 02 sensor).
4. Remove manifold bolts.
5. Remove manifold from above.
6. Install T.E.S. flange gasket and one 8mm bolt, lock
washer, and flat washer at rearmost bolt hole (leave bolt
loose enough to accept T.E.S.).
7. Place manifold into position from above. Start all bolts
and washers, then tighten.
8. Install O2 sensor on new T.E.S. manifold. Use anti-seize
compound on threads.
9. Replace spark plug wires.
10. Replace A.I.R. assembly using supplied gasket.
• RIGHT SIDE
1. Disconnect and remove spark plug wires.
2. Disconnect A.I.R. fitting from manifold.
3. Remove bolts from EGR flange.
4. Remove dip stick.
5. Remove O2 sensor.
6. Remove stock manifold from above.
INSTALLATION INSTRUCTIONS
7. Install T.E.S. flange gasket and one 8mm bolt, lock
washer, and flat washer at rearmost bolt hole (leave bolt
loose enough to accept T.E.S.).
8. Place manifold into position from above car and start one
bolt at front. NOTE: Use flat washers and lock washers
on all bolts.
9. Install all manifold bolts and tighten.
10. Re-attach EGR tube using supplied gasket.
11. Re-attach spark plug wires.
12. Re-attach dip stick tube.
13. Re-attach A.I.R. assembly.
14. Re-attach O2 sensor.
EXTENSION PIPE
1. Cut right side O.E.M. exhaust pipe approximately 1/2"
above the weld at the front of the catalytic converter.
See
Figure 1
.
2. Bolt the extension pipe with donut gasket onto the T.E.S.
manifold. Be sure to maintain equal spacing at donut
gasket for proper seal.
3. Bolt catalytic converter back into vehicle, making sure
that catalytic converter sets in original position.
4. Bolt on left side catalytic converter (use flange gasket
supplied).
5. With everything in place and properly positioned, tack
weld T.E.S. extension pipe to stock exhaust pipe in front
of catalytic converter.
6. After tack welding, remove assembly and complete weld.
7. Re-install assembly and tighten all bolts.
• FINAL INSPECTION
1. Check all hydraulic, vacuum, and fuel lines 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.
