Thank you for making HOOKER HEADERS your choice in a high-performance exhaust
system. Extensive dyno/track testing has enabled HOOKER to offer the most
advanced design in exhaust systems. The installation, while not complex, will
take a certain amount of time. However, the additional horsepower and improved
performance will more than justify your efforts. Proper installation and
maintenance will ensure long life and maximum performance from your HOOKER
HEADER exhaust system.
BEFORE STARTING
Your vehicle must be raised a minimum of 36 inches. A floor hoist is ideal. If
no hoist is available, we strongly urge the use of axle stands as a safety
measure. Please read these instructions in their entirety before attempting
installation.
CAUTION! WORK ONLY ON A LEVEL SURFACE. USE JACKS /JACK STANDS OF
SUFFICIENT CAPACITY TO LIFT AND SUPPORT YOUR VEHICLE. NEVER WORK UNDER A
VEHICLE SUPPORTED BY A FLOOR OR BUMPER JACK.
