The 7" Dynaflex chrome Rod Pickett exhaust kit with 90 degree elbow is designed to fit Peterbilt 389 models with a unibilt sleeper built in the year 2011 to 2017. It does NOT fit day cabs. The DPF/SCR step will need to be moved forward to use the classic Rod Pickett style elbows; all necessary hardware is included. The cowl panel will also likely need to be trimmed due to the step being moved forward 2 inches. The kit includes stacks, spools, and appropriate clamps and brackets required. The kit also includes re-engineered step brackets, frame brackets, replacement under carriage elbow, and a new gasket.
