PLEASE READ BEFORE PROCEEDING
PerTronix©thanks you for choosing a Patriot Exhaust Product. To realize the potential of Patriot’s engineering and excellent fit, Please Read and Understand these instructions completely prior to starting the installation. Check that you received all the parts listed on the parts list, if you have any concerns, please contact PerTronix before continuing. Headers will have the part number stamped in the flange. Work Smart – Work Safe! Most Header and Exhaust Installation are best performed on a lift. If a lift is not available, raise the vehicle and support on quality Jack Stands on level ground. Do not rely on a jack!

Many factors affect he installation of exhaust headers, including worn or aftermarket motor mounts, previous accident damage, aftermarket cylinder heads that may have relocated port or spark plug locations, suspension and steering changes, sagging of original unibody structures due to age.

Coating Notes:
Coatings can be marred during installation if you are not careful. If you are breaking in a new motor, the extreme heat can alter the appearance of the coating and this is not a warranty issue. We recommend breaking in new motors with stock manifolds or an old set of headers. We use sealing beads on all our headers. The raised bead creates a better seal virtually eliminating leaks if installed properly. It is important to install all header bolts lightly snug and then tighten to factory torque specs starting in the center and working outward.

Before starting, allow the vehicle to cool, disconnect the battery, and spray a penetrating oil on all hardware and fittings that will need to be removed. Once you remove your manifold, clean the sealing surface on the head of any old gasket debris or carbon build up.

• Must use Non Shell style motor mounts
• Cars with alternator mounted to left side exhaust will need bracket #H7806

INSTALLATION

1. Note: Some year models may require the engine to be raised slightly by removing the motor mount bolt on either side. Use a board between the pan and jack.
2. Install the headers from the bottom of the vehicle. Slide the headers into place, slip the gasket between the header and motor, and install a bolt at either end of the header to hold them in place.
3. Lower the motor, replace the motor mount bolts and check for header clearance.
4. Using the supplied header bolts, apply a small amount of anti-seize to the bolts and start the most restrictive bolts first. Tighten evenly starting in the center and working outwards.
5. Replace the clutch linkage, oil filter, dipstick tube and dipstick and alternator.
6. Cars with A/C will need to modify the bracket, see Illustration E.

8. Replace the starter and connect the wires. Reroute the wires as needed for clearance.
9. Install the reducers and determine the connection to the exhaust system.
10. Weld the reducers to the exhaust system and install them onto the headers utilizing the gaskets and bolts supplied.
11. Install the spark plugs and connect the wires to the proper plug. It may be necessary to reroute wires to clear the headers.
12. Check to make sure that all the wiring, brake lines, hoses, etc. are clear of the headers or any exhaust component.
13. Make sure all necessary brackets and accessories have been replaced and secured.
14. Connect the battery cable.

IMPORTANT CHECK LIST

• Be sure that all brake lines, transmission lines, and fuel lines are clear of headers and/or connector pipes.
