10. Attach the connector pipe to the header utilizing the metal doughnut gasket and
fasteners supplied with the headers. Do not tighten at this time.
11. Adjust connector pipes for best alignment and tighten the pipes to the headers evenly.
12. Weld the driver side connector pipe to the front of the Catalytic Converter and the driver
side connector where it slips over the Catalytic Converter inlet pipe. If you do not have
a welder available, skip this step and complete the installation. After you complete the
installation you can drive the truck to a muffler shop to complete this operation.
13. Apply anti-seize to all the O
2
sensors threads and install in their appropriate locations.
14. Plug the wires into the O
2
sensors making sure that they are routed away from hot
pipes. (We recommend that O
2
sensors be removed before any welding operation is
done on the exhaust system.)
15. Connect the negative cable to the battery.
START THE ENGINE
Start the engine and allow it to warm up to operating temperature. Check for any unusual noises or exhaust leaks.
If every thing is OK, stop the engine and tighten all bolts while the engine is still warm.
NOTE: Check the bolts periodically to make sure they have not loosened. Re-tighten after the first 500 miles and
then again at 1000 miles.
IMPORTANT CHECK LIST
Be sure that all brake lines and fuel lines are clear of headers and/or connector pipes.
All spark plug wires, battery cables, or other electrical components should be clear of headers
and/or connector pipes.
If dipstick tube was removed, make sure it is installed properly and that the dipstick has been
replaced.
Double-check the tightness of all bolts including brackets and accessories.
