Owners manual

WARNING! – Do not rely on bumper jacks or chassis jacks for support during header
installation. The subject vehicle should be raised and supported with jacking equipment and
jack stands or ramps intended for undercarriage auto maintenance. It is extremely
dangerous to work under an improperly raised and/or supported vehicle.
WARNING! - Make certain there is ample clearance around components such as brake
lines, brake proportioning valves, fuel lines, hoses and pumps, and electrical components
and wires. In some cases it may be necessary to relocate items that may be adversely
affected by exhaust system heat.
NOTE: These procedures are documented on factory standard-equipped vehicles with
original configuration compliance. Any modification of the subject vehicle may dictate
modification to these procedures.
IT IS NOT UNUSUAL WHEN INSTALLING HEADERS TO GET A BURNING SMELL.
THIS IS NORMAL AND IT WILL GO AWAY!
CAUTION! Gloves or other protection should be worn to protect installer from burns
due to hot exhaust components during these final steps!
IT IS CRITICAL that all bolts be re-tightened HOT after about 20 minutes of operation
to prevent gasket failure.
NOTE: HEADERS ARE NOT MEANT TO SERVE AS “EXHAUST SYSTEM SUPPORT
HANGERS”. Additional hangers may need to be added at the time of the installation of
the headers so that THE EXHAUST SYSTEM SUPPORTS ITSELF when the collector
bolts are removed. HEADERS THAT HAVE “SAGGED” DUE TO THE LACK OF
SUFFICIENT EXHAUST SYSTEM SUPPORT WILL NOT BE REPLACED UNDER
WARRANTY!
NOTE: Header bolts should be inspected for tightness from time to time to ensure
optimum gasket life. The bolts will STRETCH some at first due to the exhaust heat, so
they’ll loosen WITHOUT TURNING until they “take a set”. (Bolts hard enough not to
stretch would BREAK!)
E.O. STICKER INFORMATION
Place the sticker in an area that is protected from high wear or frequent exposure to
dirt, water, etc. Make sure the area is clean before applying. E.O. are usually updated
annually, your E.O.. sticker does not need to be replaced to reflect changes that are
