TURNOUTS AND H-PIPE INSTALLATION
1. Bolt the right and left side turnouts to the headers with the collector gaskets and snug the
bolts. (Note: The left side turnout is the shorter one, the right side turnout is the longer
one with an O
2
sensor fitting in it).
2. In this step, the H-pipe is modified so it can be welded directly to the new turnouts. Cut
the left and right head pipes off the old H-pipe at the weld at the front end of the leading
catalytic converters, as shown in PHOTO 1.
3. Install the H-pipe. Hold the front end of the H-pipe up to the turnouts installed in step (1).
Snug the bolts at the rear of the H-pipe to the exhaust system. Check the right and left
turnouts for a close fit for welding. Note: The right and left turnouts should just overlap
the leading edge of the catalytic converters.
4. Weld as much of the right and left turnouts as you can reach with the H-Pipe installed.
Remove the partially welded H-pipe/turnout assembly and complete the welding.
5. Install the right O
2
sensor in the right turnout. Install the newly welded H-pipe assembly
and tighten the bolts and reconnect the remaining three (3) O
2
sensors to their harness.
6. On hard top models, install the A-arm brace.
7. Install cold air tube to the throttle body and the air cleaner.
8. Reconnect E.G.R. tube to the throttle body.
9. Install the dipstick tube bolt.
10. On Cobra models, reinstall the upper tower support bracing.
11. Inspect the steering shaft for proper installation.
12. Ensure that all electrical connections that were disconnected are properly reconnected.
13. Ensure all electrical wires are secured so as not to come into contact with the headers.
14. Reconnect the battery.
