JBA Headers for 2010-2011 Chevy Camaro 3.6L V6
Part #1816S
CARB EO # D-57-25
Read all instructions carefully before attempting installation.
Rev. 2, 3-18-13 DSL
PerTronix© thanks you for choosing JBA HEADERS, the best fitting, highest quality header on the market. In
order to realize the full potential of our good fit, please read and understand these instructions completely prior to
starting work.
Check to make sure you received the proper parts for your application. The header number will be stamped on the
engine flange. If you are unsure you have received the proper parts call before you start work.
Be sure to work safe! Whenever you work under the vehicle be sure that it is located on level, solid ground and is
supported by adequate safety stands! Remember: Hot asphalt will not support most jack stands!
Many factors affect the installation of headers, some of which are broken or aftermarket motor mounts, accidents
that impact the configuration of the frame, and/or the installation of different engines or aftermarket cylinder
heads.
Attention Customers breaking in new engines: Due to the extreme heat generated during the break-in process,
the appearance of the ceramic coating may be altered in certain areas. The protection characteristics and thermal
barrier properties of the coating is never compromised. It is recommended that a cast iron manifold or old set of
headers be used for this process.
Notice: The coating of these headers can be marred or scratched during installation. If the header needs to be returned and is damaged, you will be charged for recoat.
JBA uses sealing beads on all its headers. We have found that when installed correctly, the raised bead around each port
increases the pressure exerted on the gasket directly adjacent to the port and effectively prevents leaking gaskets. It is
normal for the flange to be raised off the cylinder head the thickness of the sealing bead. It is important when installing
the header, to install all bolts loosely, then tighten evenly to ensure the flat installation of the flange. The torque sequence
from one flange to another will vary, but generally every bolt on a header should be first fit snug, starting from the inside
of the flange working out, alternating from top to bottom so that the bolt connects the flange to the manifold to the point
where they barely touch. Second, using the same inside-out pattern, tighten each bolt until finished. This method will
help prevent leakage and will give the user the best possible performance out of their pair of headers.
INSTALLATION OF THESE HEADERS REQUIRES WELDING
READ ALL INSTRUCTIONS BEFORE ATTEMPTING INSTALLATION
Place vehicle in a location where the floor is solid and flat, with adequate lighting. Do not attempt to work
on a hot engine. Heat causes metal to expand and makes removal of fasteners difficult at best. Disconnect
the battery cables from the battery. Raise the front of the vehicle to obtain adequate access to the bottom
exhaust manifold flanges. Use large-base jack stands to support the vehicle. Do not rely on the jack! Block
the tires to prevent the vehicle from rolling off the jack stands.
FROM ABO VE-
1. Disconnect Neg. Battery cable.
2. Remove plastic engine cover.
3. Remove the three bolts(10mm) attaching the heat shield to each exhaust
manifold. Remove the heat shields, the drivers side will come out the top, the pass side will drop out through the
bottom.
4. Remove one of the 15mm nuts attaching the Cat. Converter assembly to the manifold on each side. Note- Leave
one nut on each side very loose to keep the Cat assy. from falling on your head when you work underneath.
6)- Find O2 sensor leads at rear of cylinder heads. Remove locking clip, disconnect O2 sensors.
FROM BELOW
7. Loosen the 15mm nuts on the band clamps connecting the exhaust pipes to
the Cat assy’s.
8. Release the clip and slide the band clamps to separate the pipes.
9. Unplug the rear O2 sensor leads, remove the nut that you left loose in step 4 and remove the Cat assy’s.
ABOVE AND BELOW
10. Remove the Dip Stick and tube as it passes through the manifold. Remove the bolts(13mm) attaching the
exhaust manifolds to the cyl. heads. Remove the manifolds.
11. Clean the carbon build up from the head surface. Be careful not to gouge the aluminum.
12. Wipe the gasket clean of any residue.
13. Swap the front O2 sensors into the headers. Use a dab of anti-seize to protect against galling.
14. Inspect the gaskets and replace with new factory GM if necessary, install the headers using the supplied
bolts. Use care to insure the headers are tightened evenly.
15. Measure 3/4” from the weld on the inlet side of the primary cat and mark the tube. Carefully cut the tube at
your mark.
16. Install the adapter flanges to the header using the supplied clamps. Use anti-seize on the clamp bolts. Tighten
“snug”, but don’t final tighten yet.
17. Slip Cat assy’s into adapter flanges, and connect to exhaust pipes using the original band clamps. Align the
exhaust and Cat assy’s into the adapter flanges, tighten the factory band clamps. Make sure that you have the
cats lined up with the header adapter flange and that the exhaust is completely back in the factory original position. This is critical to the car running correctly and maintaining calibration. The cats will
slide inside the adapter flange. It is in the right position when the factory weld butts up against the end of the
JBA adapter flange.
18. When you are confident that the cats are back in the factory original position, Tack weld the Cat and adapter
in at least three places on each side, making sure that it won’t move when you remove for final welding.
19. Careful remove the Cat assy’s and finish weld the adapters to the Cat’s. be sure you have no pinholes in your
welds
20. Install the Cat assy’s. Connect exhaust. Align Cat’s and exhaust, Tighten all connections securely. Plug all
four 02 sensors back in.
21. Re-check all steps, check for proper clearance on all fuel lines, brake lines, and wiring harnesses. Reinstall
the oil dipstick.
22. Start engine, and check for leaks.
23. Warm engine, allow to cool, re-torque headers.
