Disassembly
1. Disconnect negative battery cable.
2. Remove side exhaust covers. NOTE: Have someone
assist you to prevent damage to side covers or body.
3. Remove two O2 sensors from stock exhaust.
4. Remove rubber mounts and bracket holding stock
exhaust system at front of side pipes. They will not
be re-installed.
5. Remove bolts holding the exhaust pipe to exhaust
manifold.
6. Remove starter.
7. Number spark plug wires and remove from spark
plugs. Lay the wires over the rear of the engine to
prevent damage to wires.
8. Remove plastic spark plug wire separators from
valve cover area.
9. Remove top of heater air box (right side).
10. Unplug wire from temperature sending unit on left
cylinder head.
11. Remove the retaining nuts securing the heat shields
to exhaust manifolds. NOTE: The right side will
come off easily. The left side will only come off after
all manifold retaining bolts have been removed and
the manifold is completely loose. You may need to
remove the front bolt that holds the water pipe to
allow you to remove the heat shield and manifold.
12. Remove stock exhaust manifolds.
13. Clean gasket surfaces on cylinder heads.
NOTE: Be careful not to damage soft aluminum.
14. Cut stock exhaust at inlet of catalytic converter.
Assembly - Left Side
1. Install upper half of header from top along with new
gasket, bolts and washers supplied.
2. The thick hardened flat washers will be used on the
three slotted holes on each header flange.
3. Start all ten bolts but leave bolts loose at this time.
4. Install lower half of header from under car. Place
outlet end over frame rail and rotate into place.
Install gasket and 3/8" Allen head bolts and self-
locking nuts supplied.
5. Tighten cylinder head flange bolts evenly.
6. Tighten connector flange bolts evenly. NOTE: It is
