Part vii: exhaust
AEV’s HEMI exhaust is designed specifically for the 5.7L HEMI but can be used for 6.1L and 6.4L engines
as long as the 5.7L manifolds, gaskets, and bolts are used. The exhaust is designed around the stock
suspension and bumpers and may need to be modified to accommodate aftermarket suspensions,
bumpers, or other accessories.
DO NOT TIGHTEN ANY PART OF THE EXHAUST SYSTEM UNTIL THE FINAL DESIRED FIT IS ACHIEVED!
1. Install the hanger mount into the existing cross member hole behind the transfer case.
2. Adjust for clearances paying particular attention to the area around the front driveshaft, JK cross
member, transmission pan, rear trackbar, and rear bumper.
3. The right hand down that goes under the transmission oil pan should be parallel with JK cross
member when fitted properly.
4. You may wish to tack weld all joints for increased durability.
5. Install the star washers on the four isolator hangers.
6. Refer to the included photos for placement of exhaust pieces.
