verter assembly.
NOTE: The O2 sensors have a permanently attached wire. DO NOT try and remove the wire from the
sensor. These are fairly delicate sensors, use extreme care not to drop or bump them as permanent dam-
age could occur. When Re installing DO NOT get anti seize on the probe of the sensor as this could cause
premature failure.
4. Remove the spark plug wires (do not pull on plug wires, twist the plug boot) and spark plugs.
DRIVER’S SIDE
5. Carefully unplug and remove the O2 sensor from the manifold, set aside so it doesn’t become damaged. Dis-
connect A. I. R. tube from driver’s side factory manifold. Unbolt the manifold and remove it.
6. Remove the gaskets and any gasket material or any carbon deposits that remain on the head surface. The use
of a gasket removal agent or scraper will ease the removal of any gasket material. Use care not to get debris into
ports or spark plug holes.
7. Apply a small amount of anti-seize to the threads of the supplied header bolts. Install the driver’s side header
using the supplied bolts and gasket. Torque to 18 ft/lbs on Aluminum heads or 25 ft/lbs on Iron heads. Re-install
the A. I. R. tube using the supplied gaskets and 1/4” bolts. Apply a very light coating of anti seize to the O2 sen-
sor and install the O2 sensor into the header. Hook-up O2 sensor wire.
PASSENGER SIDE
8. Carefully unplug and remove the O2 sensor from the manifold, set aside so it doesn’t become damaged.
Disconnect A. I. R. tube from driver’s side factory manifold. On 98-2000 models unbolt the EGR tube from the
manifold. Remove the dipstick tube. Unbolt the manifold and remove from underneath car.
9. Remove the gaskets and any gasket material or any carbon deposits that remain on the head surface. The use
of a gasket removal agent or scraper will ease the removal of any gasket material. Use care not to get debris into
ports or spark plug holes.
10. Apply a small amount of anti-seize to the threads of the supplied header bolts. Install the driver’s side header
using the supplied bolts and gasket. Torque rthe header bolts to 18 ft/lbs on Aluminum heads or 25 ft/lbs on Iron
heads. Re-install the A. I. R. tube using the supplied gaskets and 1/4” bolts. On 98-2000 models re install the
EGR tube using the supplied gasket. Reinstall dipstick tube.
Apply a very light coating of anti seize to the O2 sensor and install the O2 sensor into the header. Hook-up O2
sensor wire.
11. Install the factory Y-pipe/converter using the supplied fasteners and gaskets. Reinstall the O2 Sensors in the
Y pipe.
12. Check to make sure that all the wiring, fuel lines, transmission cooler lines, brake lines, hoses, etc. are clear
of the headers or any exhaust components and reroute or relocate those components as necessary.
13. Reconnect the battery cable.
14. Start the engine and let it warm up. Check for leaks. Shut engine off and let it cool down. Check to make
sure all fasteners are tight.
15. Periodically check and retighten the header bolts.
