2" OD HEADER PIPE SIZE EXHAUST SYSTEMS (Fig. 3)
1. Remove the existing exhaust system. It is up to the technician as
to what other parts should be removed in order to successfully
remove the exhaust system.
2. Insert the backing washer (I) into the cylinder head.
3. With the backing washer (I) located in the cylinder head, install
the exhaust gasket (H).
4. Install the new S&S flange retaining ring (G) over the 2" weld-on
pipe (J).
5. Install the exhaust flange (A) over the 2" weld-on pipe (J) so that
the step in the flange is on the side facing the cylinder head and
mates with the flange retaining ring (G). See Picture 3 below for
reference.
Failure to install the flange (A) and retaining ring (G) correctly will
result in insufficient clamping and/or a leaking exhaust system.
6. Insert the flange-pipe assembly into the cylinder head and snug
the exhaust nuts to hold it in place.
7. Repeat steps 2-6 for the other head pipe and cylinder head.
8. Begin creating your own exhaust system or if you are modifying
an existing system, cut the end of the head pipe to fit the weld-
on pipe (A).
NOTE: The inner diameter of the 2" weld-on pipe (J) is designed to fit over
2" OD exhaust pipe.
