5. Starting from below, work the head up through the chassis into position.
NOTE: If the engine is equipped with Air Injection Tubes, remove them from the stock exhaust manifold and install in the fittings on
the header.
6. Place the gasket into position and start all bolts (most restricted first).
7. Use Hooker muffler P/N 21021HKR or 21002HKR, that slips into the sidepipe before the pipe is installed.
8. Before tightening the header flange bolts, slip the sidepipe over the collector. Brackets are positioned on the sidepipe to align with
the holes in the frame. To install the mounting bolts, insert the head of tab bolts into the slotted holes in the frame and rotate one-
quarter turn (See Figure C for side-mount mounting procedure.)
Figure C
NOTE: Due to the differences in bodies and chassis, it may be necessary to enlarge the mounting holes approximately 1/2” forward to
ensure that the sidepipe bottoms onto the header collector. This is not required for all models.
9. Tighten all header flange bolts evenly and all sidepipe mounting bolts. Replace all screws in the rocker panel molding.
10. Replace the clutch linkage, dipstick tube, and spark plugs. Replace the generator/alternator (if removed). If mounted on the head,
use the furnished bracket to reinstall. See Figure D. If the header is equipped with smog bushings, the bracket must be notched to
clear the bushings. See Figure E.
