PLEASE READ BEFORE PROCEEDING
PerTronix©thanks you for choosing a JBA Performance Exhaust Product. To realize the potential of JBA’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 Installations 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! 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.
- Unplug the Oxygen Sensors from the exhaust system. Disconnect the exhaust system from the catalytic converter assembly. Remove the converter assembly from the vehicle.

- Remove the motor mount nut under the passenger side manifold.
- Place a block of wood between the oil pan and a jack. Remove the passenger side motor mount bolts and lift the motor approx. 1”
- With engine jacked up, remove the passenger side manifold and remove the manifold studs. Note: On 96-97 Cobra installations you will need to disconnect the air fitting from the front of the manifold.
- Due to the limited space in the engine compartment, you will need to relocate the air conditioning line that run by the passenger side manifold. This is done by bending the soft aluminum line up slightly and reattaching it using the factory bracket into the alternate hole located approximately 2 ”above the factory’s original mounting hole. See the illustration below.
