Owners manual

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!) We’ve
experimented with the various “locking devices” on the market, which prevent from turning. They
DON’T WORK on HEADER BOLTS, and they greatly complicate the process of re-tightening the
bolts when it’s necessary.
What “WORKS”:
Go over the bolts again after the first DAY of driving (or about 100 miles- whichever comes first), then
after the first WEEK, after the first MONTH, and then EVERY 6 MONTHS. Our exclusive gaskets are
specially made so that the cylinder head SHOULD begin to melt before the gaskets can burn up.
About the only way to kill these gaskets is to let the headers get loose and then keep driving with a
leak.
Due to varying conditions between geographical locations and usage, we strongly recommend having
the engine re-tune at a reputable tune-up shop after the installation of the headers. Doing so will
ensure that you get the maximum benefit from the installation of the headers.
GIBSON PERFORMANCE strives to deliver the highest quality materials, workmanship, and
service. Please so not hesitate to call our technical line if you have a question or experience a
problem.
WE TRULY WISH TO HAVE ONLY SATISFIED CUSTOMERS!
