PLEASE READ BEFORE PROCEEDING
PerTronix0thanks 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 Per Tronix 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!
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.
- From underneath the vehicle, remove nuts attaching the manifolds to the exhaust pipe.
- Remove bolt attaching steering shaft to steering rack. Slip shaft off of rack.
- From above, remove bolt attaching oil dipstick to head. Dipstick will pivot out of the way.
- Carefully remove spark plug wires. Twist boot prior to tugging on them. Do not pull directly on the wire. Remove spark plugs.
- Remove bolts attaching manifolds to head. Remove manifolds.
- Clean gasket surface, be careful not to gouge the head.
- Install headers using gaskets and supplied hardware.
- Re-install spark plugs, and plug wires. Re-attach dipstick using spacer provided.
- From underneath, connect headers to exhaust pipes, placing a flat washer over the stud, and re- using factory nuts. Re-connect steering shaft, and secure.
- Check to ensure there is adequate clearance on all fuel lines, brake lines, battery cables, wire harnesses, etc.
- Re-check everything!
- Start engine, check for leaks and test drive. Then let engine cool and re-torque header bolts.
