Stainless Works Ford Mustang 2005-10 Headers - Manual (Page 2)

To install headers:
1. Install headers up from the underside of the car and bolt in place using
aftermarket bolts such as those available from manufacturers such as ARP or
Breslin (available from your favorite speed shop) and factory gaskets. We
recommend purchasing a new set of factory gaskets.
2. Reinstall steering rack bolts and motor mount nuts and tighten to factory torque
specifications.
3. Install new O2 extensions – tabs may need to be removed.
4. Unbolt electrical solenoid on driver’s side fender well to gain access to reinstall
dipstick tube. Reinstall dipstick tube and reinstall solenoid. Reinstall air box.
5. Slip one clamp onto each header followed by the high flow converters or off road
pipes.
6. Install the converter outlet pipes with one clamp on each end. If you are
connecting to the stock exhaust system, or an aftermarket 2 ½” exhaust system,
use the supplied adapter stubs from the rear lead pipes to reduce down to the
correct size.
7. Reinstall the factory exhaust system in the reverse order it was removed. Once all
pipes fit properly, we recommend breaking the exhaust apart and using red high
temp RTV at each joint to ensure a leak proof seal. Tighten all clamps making
sure that there is adequate clearance. Reinstall the O2 sensors, using a small
amount of never seize on the threads. Be sure to only apply never seize to the
threads-if this is applied to the O2 element it will ruin the O2 sensor. Connect to
the factory harness using the supplied extension harness. Zip tie the extender
harnesses out of the way.
8. Reconnect battery, start car and warm up. Let cool thoroughly and retighten all
header bolts and clamps. Drive car and enjoy your newfound power.
