Installation of MBRP Inc. Header Kit
Reference the torque specs at the bottom of this page during assembly.
1. Install the OEM Manifold Gaskets onto the Cylinder Head with 4 of the
supplied M8 Flange Head Bolts in the BOTTOM ROW ONLY on both
sides.
2. O2 Extension Harnesses may be required for installation. You may
be able to open the harness and pull more slack in the OEM O2
wiring. MBRPinc can provide Extension Harnesses if required.
0262049
07-10 Front/Rear O2 Sensor Extension 12”
0261675 11-12 Front O2 Sensor Extension 12”
0261676 11-12 Rear O2 Sensor Extension 12”
These connectors are very hard to access once the Headers are
installed.
Refer to Figure 11.
3. Install the MBRP Headers into position and lower them down
onto the bolts previously installed in the Cylinder Heads. The Header
Flange is slotted to allow this. Be careful not to damage the Gaskets
while installing the headers. Install the Dipstick assembly while the
Driver Side Header is loose. Secure it with the bolt removed in Step 11.
Refer to Figures 12 and 13.
4. Install the remaining M8 Flange Head Bolts and tighten to 25 lb-ft. A
10mm ratchet wrench will be extremely helpful with this step.
5. Reinstall the Driver Side Engine Mount and torque to specification. Lower the engine onto the mounts,
reinstall the Engine Mount Nuts and torque to specification.
6. Remove the OEM O2 Sensors from the Driver Side Manifold/Passenger side H-Pipe and transfer them to the
MBRP headers. Connect the O2 Sensors to the O2 Extension Harnesses. Use wire ties to secure the wiring
away from the exhaust.
7. Reinstall the Starter and Oil Filter.
8. Reinstall the Steering Shaft, and Lower Chassis Brace.
Torque to specification.
9. Reinstall the Air Intake, Airbox Assembly, EGR Tube,
Battery box, and Battery.
