32. Connect the fuel lines (you will need the blue clip you saved earlier).
33. Install AEV supplied exhaust system. Refer to photo group B.
PLEASE NOTE: The supplied AEV exhaust system is designed to fit both the 5.7L and 6.4L engine in a stock
application. BOTH the 5.7L and 6.4L engines will require the use of the 5.7L exhaust manifolds, gaskets,
and bolts that are listed in the Bill of Materials. The routing has been configured assuming a stock suspen-
sion and bumpers. The use of aftermarket suspensions, bumpers or other components may require modifi-
cations to the exhaust system or other components. We find it easiest to start from the rear of the chassis.
DO NOT tighten the exhaust at this time. Refer to photo group B.
a. Install the cross member hanger (fig 29).
b. Install the supplied isolators onto the frame (fig 30).
c. Install the exhaust system (photo group B).
d. Shorten one of the down tube to manifold bolts by 3/4” to use in upper mounting location.
e. DO NOT TIGHTEN EXHAUST AT THIS TIME
