STEP 8
• Using a floor jack or jack of some sort, and a
piece of wood on the oil pan rail, slowly raise
the engine enough to allow the header to be slid
into place. Place another piece of wood as a
safety block between the engine mount and
cross member until the header is installed
completely with supplied gasket and hardware.
The starter motor must also be installed
simultaneously with the passenger side header
due to tight clearances.
• Lower the engine and re-install the engine
mount nut, then simply slide the driver side
header into place along with supplied gasket
and hardware.
• Install the oxygen sensors to the H-Pipe or X-
Pipe assembly before installing onto the vehicle.
Install the new BBK H-Pipe or X-Pipe assembly
using the supplied hardware, first tighten the
flanges at the header collectors, then tighten at
the mufflers. NOTE!!! Be sure to add a small
amount of anti-seize to the top thread of
each oxygen sensor using the supplied anti-
seize packet. As you thread the oxygen
sensor back into the part the anti-seize will
spread evenly throughout the threads.
• Re-install the steering shaft to steering rack and
torque the bolt to factory specifications, then re-
install the cross member support bar. At this
point check for any interference or clearance
problems between the driver side header and
steering shaft.
• From under the hood simply reconnect the
emissions tubes to the appropriate fittings on
the headers and re-install the strut tower brace.
NOTE!!!
Be sure to apply a small amount of
the supplied anti-seize on the threads.
