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 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.
DISASSEMBLY
- Unbolt the H-Pipe assembly from the collector flanges of the factory headers. Insure that no pressure is placed on the O2 sensor wires, disconnect if necessary. The H-Pipe does not need to be removed.
- Unbolt the dipstick tube bracket from the engine and remove the dipstick tube. Unbolt the engine lift brackets and discard.
- Unbolt the Driver’s side exhaust manifold and remove. Remove the gaskets and any gasket material or any carbon deposits that remain on the head surface. Clean excess carbon deposits from the H-Pipe mating flange.
- It may be necessary to grind the Oil Dipstick tube mounting tab to clear the header tube. See Illustration below. Once it is clearance, insure that it is clean, apply a small amount of sensor safe silicone around the end of the tube where it slip into the block and reinstall the tube.
- From above, slip the header into position. Slide the gasket into place and install the supplied header bolts and lock washers. Anti seize is recommended on aluminium heads. Tighten the bolts starting from the center and working out.
- Remove the passenger side EGR tube from the stock manifold. Unbolt the passenger side manifold and remove. Remove the gaskets and any gasket material or any carbon deposits that remain on the head surface. Clean excess carbon deposits from the H-Pipe mating flange.
- From above, slip the header into position. Slide the gasket in to place and install the supplied header bolts and lock washers. Anti seize is recommended on aluminium heads. Tighten the bolts starting from the center and working out. Use the 3/8″ X 2″ bolt with the spacer in the rear most header bolt hole. The EGR Tube tab will bolt to this bolt to space the tube out from it’s original location.
- Apply a light coating of Sensor Safe Hi Temp Silicone to the collector dome on both headers. Install the supplied collector bolts into the collector flange holes from the topside. Have an assistant hold a wrench on the bolt head from the topside when putting the nuts on and tightening from the bottom side. The procedure is the same for both sides.
- Reinstall the spark plug wires and looms taking care not to let any wires rest against the headers.
- Reinstall the negative battery cable.
- Check that all bolts are tight. Make sure that all wiring, fuel lines, transmissions lines, brake lines etc are clear of the headers and the exhaust and relocate as necessary.
- Start the engine and let it warm up. Check for leaks. Shut engine off and let it cool down. Check to make sure all fasteners are tight
