2007-08 5.4 Ford Mustang Shelby GT500

Part # 6695S

WARNING: These headers are legal for Off Highway use (except in California or states that have adopted Cali­fornia emission standards) or Racing use (which may never be used on a Highway), or for use on pre emission

controlled motor vehicles/motor vehicle engines (pre 1974 domestic vehicles certied to California standards, pre

1974 domestic vehicles certied to Federal standards and all pre 1974 Foreign vehicles) Only.

Read all instructions carefully before attempting installation.

PerTronix© thanks you for choosing JBA HEADERS, the best fitting, highest quality header on the mar-

ket. In order to realize the full potential of our good fit, please read and understand these instructions

completely prior to starting work.

Check to make sure you received the proper parts for your application. The header number will be

stamped on the engine flange. If you are unsure you have received the proper parts call before you start

work.

Be sure to work safe! Whenever you work under the vehicle be sure that it is located on level, solid

ground and is supported by adequate safety stands! Remember: Hot asphalt will not support most jack

stands!

Many factors affect the installation of headers, some of which are broken or aftermarket motor mounts,
accidents that impact the configuration of the frame, and/or the installation of different engines or after­market cylinder heads.

Attention Customers breaking in new engines: Due to the extreme heat generated during the break-in

process, the appearance of the ceramic coating may be altered in certain areas. The protection character­istics and thermal barrier properties of the coating is never compromised. It is recommended that a cast
iron manifold or old set of headers be used for this process.

Notice: The coating of these headers can be marred or scratched during installation. If the header needs

to be returned and is damaged, you will be charged for recoat.

JBA uses sealing beads on all its headers. We have found that when installed correctly, the raised bead around
each port increases the pressure exerted on the gasket directly adjacent to the port and effectively prevents leak-

ing gaskets. It is normal for the flange to be raised off the cylinder head the thickness of the sealing bead. It is
important when installing the header, to install all bolts loosely, then tighten evenly to ensure the flat installation
of the flange. The torque sequence from one flange to another will vary, but generally every bolt on a header
should be first fit snug, starting from the inside of the flange working out, alternating from top to bottom so
that the bolt connects the flange to the manifold to the point where they barely touch. Second, using the same
inside-out pattern, tighten each bolt until finished. This method will help prevent leakage and will give the user

the best possible performance out of their pair of headers.

For renement, both Ford V-8 engines are installed using hydro mount bushings on either side of the block.

These liquid-filled engine mounts are tuned to quell specific unwanted vibration. Under extreme driving con­ditions these mounts allow excessive engine movement. We recommend replacing these motor mounts with

performance mounts available from Steeda PN# 555-4005.

1. Remove both battery cables. Remove the battery hold down strap. Remove battery from car. Disconnect wire loom attach­ment at inside forward corner of battery box. Remove three bolts securing battery tray to chassis, remove tray

2. Loosen the clamp securing the air inlet hose to the throttle body. Remove the bolt attaching the air box to the chassis. Dis­connect the vacuum line, wire harness, and PCV connector, from the air inlet hose. Remove the air box, and air inlet hose.

3. Remove the four nuts attaching the strut tower brace to the chassis. Remove strut tower brace.

4. From Underneath:

Loosen clamps attaching exhaust pipes to catalytic converter assy. Release retaining clip, and slide clamp rearward onto
axle pipe.

5. Unclip O2 Sensor plugs, remove nuts attaching pipe to manifolds, remove converter assy from car.
