How to Install BBK Off-Road X-Pipe on your Mustang

Installation Time

45 minutes

Tools Required
  • Sawz-All
  • WD-40

Follow these instructions carefully to ensure correct fitment and operation.

STEP 1

• Place all four corners of the vehicle on jack stands or use a drive on lift.


STEP 2

• Disconnect the negative battery terminal.

STEP 3

• Remove the oxygen sensors using a 22mm wrench. Then take off the header flange nuts at the collector and disconnect the air tube from the H-Pipe. (In some instances cutting 1-2 inches in front of the factory clamp for the air pump tube on the H-Pipe may be necessary). 

STEP 4

• Disconnect the mufflers from the mid-pipe. Lubricate the H-Pipe hangers with WD-40 or equivalent and slide back to remove. 

STEP 5

• For installation simply reverse the previous steps, making sure to reconnect the air tube to the connector tube located on the new mid-pipe (Used supplied hose and clamps if cutting was required). 

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.  NOTE!!! Do not plug off the air line from the air pump. Air pump damage and premature catalytic converter damage will occur.

STEP 6

• Using the supplied muffler style clamp, install over the mid-pipe crossover tube and tighten to avoid any leaks. This part can also be welded to avoid any exhaust leaks.
