We realize that you had many choices when you made your purchase, we thank you
for purchasing FLOWTECH
®
. AT FLOWTECH
®
we put our many years of perfor-
mance exhaust experience into every product we build. We feel and know you will
agree, FLOWTECH
®
products are the best you can buy at any price.
As a result of the restricted room available on some applications, you may
experience a close fit to some body and chassis components. This is a normal
condition. If this is your first time installing an exhaust product, it may be time
consuming. While not complex, stick with it. As soon as you start your engine
the reward of additional horsepower and performance will be well worth your
efforts.
READ THESE INSTRUCTIONS CAREFULLY BEFORE STARTING:
For the ease of installation, your vehicle must be raised a minimum of 24".
Warning: Should you decide to install any exhaust products yourself, be warned
that the original equipment jack that came with the vehicle is intended for
emergency use only. The use of a frame jack, in conjunction with a floor jack
as the main support, is highly recommended to minimize the accidental drop-
ping of a vehicle while the installation proceeds. Never go under any vehicle
that is supported by a bumper jack!
TOOLS REQUIRED: 3/8" drive rachet, 5/8" and 11/16" sockets, 5/8", assorted
socket extensions, 10mm, 11/16" and 7/8" wrenches, lubricant (wd-40 or equiva-
lent) and the proper lifting devices mentioned in the above paragraph.
1. REMOVING THE FACTORY H-PIPE:
A. Disconnect the battery to prevent accidental damage to the electrical system.
B. Disconnect the stock H-pipe from the exhaust manifolds or headers, using
the 5/8" socket with the long extension to remove the four nuts.

system using the 5/8" socket.
D. Loosen the clamps that hold the air tube to H-pipe using a 10mm wrench.
