15. Reinstall the passenger side spark plug wiring harness looms (and if applicable, the dipstick
tube support bracket). (Note: The dipstick tube may require slight, careful bending to conform
to its new location. Allow at least ¼” clearance between the dipstick and the header.
16. If applicable, reinstall the passenger side A.I.R. harness on the header, tighten securely, and
reconnect the feed hose.
17. Reinstall all spark plug wiring.
18. Install the supplied catalytic converter adapter into the entrance of the catalytic converter, with
the bolt hole clocking as shown on Page 6, Figure 3. Use a hammer and block of wood to drive
the adapter in until it stops, then reinstall the factory clamp loosely.
19. Attach the supplied Y-pipe assembly to the header collectors and the catalytic converter
adapter using the appropriately sized supplied collector gaskets, 3/8”-16 x 1 ¼” hex head cap
screws, nuts and washers. Assemble loosely so that it can be properly aligned later in the
assembly procedure.
20. If applicable, the supplied heat riser (replaces your original heat riser) should also be installed
between the passenger side header collector and the Y-pipe assembly at this point, using
another supplied
2 ½” collector gasket and the 3, 3/8”-16 x 2 ½” hex head cap screws (instead
of the 1 ¼” hex head cap screws), nuts and lock-washers. (See Page 6, Figure 4 for an
exploded view of the heat riser assembly).
21. Reattach the vacuum tube to the heat riser.
22. Check for proper alignment of the Y-pipe and tighten the bolts.
23. With the exhaust system aligned properly, tighten the catalytic converter adapter clamp.
24. If applicable, attach the supplied Hot Air Pickup Tube as shown on Page 6, Figure 4.
25. An example of a completed assembly is shown on Page 7, Figure 5.
26. Reinstall the air cleaner assembly.
27. Connect the negative battery cable.
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.
Perform these checks again after the first 1000 miles.
START THE ENGINE
Start the engine and allow it to warm up to operating temperature.
Caution! Hot parts! Wear protective clothing as needed.
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.
