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.
DISASSEMBLY
- Unbolt the head pipes form the manifolds and push the head pipes out of the way.
- Remove clutch linkage on stick shift car or auto trans shift rod and key lock rod on automatic cars.
- Remove starter, starter brace, frame/fender brace, dipstick tube, oil filter and oil filter adaptor, and vacuum canister for the heat riser.
- Cars with the brake pressure valve and warning light switch mounted to the inside of the driver’s side frame will need to be relocated to the top of the frame.

Position the gasket, and use 1” long bolts and flat washers at the notches in the flange, then slide the header over the bolt and start the remainder of the bolts.
NOTE: A. Cars equipped with power steering or alternator bracket mounted in #1 cylinder, use the stock bolts. Washers may be required as spacers for proper alignment.
B. Models equipped with heat shields over the motor mount must either modify the heat shields for maximum clearance or discard them. -
Replace the starter, dipstick tube, clutch linkage (if removed), shift rod or steering lock pad, and vacuum operated heat riser.
