PerTronix JBA Exhaust 1410S - Manual (Page 2)

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.
NOTE: Installation of this product requires an adequate workspace, general mechanic’s tools, general mechanical “know-how” and
a reasonable degree of experience. Most auto enthusiasts with these resources will have little difficulty installing these headers.
However, you should carefully read these instructions before attempting to install these headers. If in doubt, consult a professional
mechanic. (Better to do it now than to get stuck halfway through the installation.)
By installing your JBA Performance Exhaust product, you indicate that you have read this document and agree with the following
terms. The Purchaser is responsible for following all installation instructions and safety guidelines supplied with JBA Performance
Exhaust products.
PerTronix© assumes no responsibility for damages resulting from improper operation, misuse, abuse, or lack of responsible care, or
any problems resulting from incompatibility with other manufacturer’s products.
Included with your installation instructions is a copy of the product warranty. Please read it carefully before you begin any work on
your vehicle.
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 ad-
equate 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 con-
figuration of the frame, and/or the installation of different engines or aftermarket cylinder heads.
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 compro-
mised. 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 important when installing the
header, to install all bolts loosely, then tighten evenly to ensure the flat installation of the flange. It is normal for the flange to be raised
off the cylinder head the thickness of the sealing bead.
To prevent leakage, it is important to tighten the flanges on any set of JBA headers carefully by using the proper procedure. 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 Instructions
1. Place the 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 fasteners more difficult to remove and can cause burns.
2. Remove negative battery cable.
3. If a lift is not available, raise the front of the vehicle2 feet or higher to obtain adequate access to the exhaust system. Use large base
jack stands. Do not rely on a jack. Block the tires to prevent the vehicle from rolling off the jack stands
4. Apply penetrating oil to all fasteners before attempting to remove them.
5. From underneath, remove the four nuts connecting the exhaust to the catalytic converters. Remove the two 12mm headed bolts
from the front exhaust hanger. Push the exhaust system back as far as it will go (about 1 ”).
DRIVERS SIDE
1. Remove the three bolts attaching the heat shield to the exhaust manifold. Wiggle the heat shield off to the side to get access to the
upper stud on the catalytic converter.
2. Disconnect the O2 sensor plug. Remove from the bracket.
