DISASSEMBLY
1. Disconnect negative battery cable.
2. Raise vehicle and remove O2 sensor from catalytic
converter, being careful not to damage.
3. Unbolt and remove exhaust pipe/catalytic converter
assembly. Before removing exhaust pipe/catalytic
converter assembly, determine the position of
catalytic inlet for re-installation.
measurements or mark bottom of floorboard with
chalk to show catalytic location. (Do not damage
converter).
4. Cut head pipes off from catalytic converter
approximately 1/2" ahead of weld (See Figure 1).
RIGHT SIDE
1. Remove air inlet from engine to intake manifold.
2. Remove spark plugs.
3. Unbolt E.G.R. flange from manifold.
4. Remove manifold and studs.
5. Install T.E.S. flange gasket and T.E.S. manifold from
top. Install header bolts supplied, and leave loose
enough to ensure proper alignment.
NOTE: Use flat washers at slotted ends and lock
washers on all bolts.
6. Re-attach E.G.R. tube (1996 only - install block-off
plate supplied on T.E.S.).
7. Install right extension to catalytic (slip over the top
catalytic nipple) and bolt onto right T.E.S. manifold
with donut gasket in place.
8. Tighten flange bolts. Be sure to locate donut gasket
with equal space all around for the best seal (See
Figure 2).
9. With everything in place, tack weld extension pipe to
catalytic converter.
NOTE: Tack welding should not be done until the
entire system is securely bolted in place.
welding is desirable but gas welding can be used.
LEFT SIDE
1.
Remove spark plugs.
2.
Remove exhaust manifold and studs.
3.
Install T.E.S. flange gasket and T.E.S. manifold from
top.
4.
Install left crossover pipe with donut gasket over
catalytic nipple and bolt onto T.E.S. Be sure to

locate donut gasket with equal space all around for
the best seal (See Figure 2).
With everything in place, tack weld left crossover
pipe to catalytic converter.
NOTE: MIG welding is desirable but gas welding
can be used.
After tack welding, remove assembly and complete
weld.
Re-install assembly and tighten all bolts.
Re-install spark plugs and wires.
Check all wires and lines for adequate clearance.
Check all hydraulic, vacuum, and fuel lines to
ensure there is adequate clearance to T.E.S.
components.
Re-connect battery.
At this point, it is a good idea to look everything
over and make sure that nothing was missed in
assembly.
Start vehicle and bring up to normal operating
temperature. Check for possible leaks.
Turn engine off and let cool. Tighten all bolts again.
