3 Slide the pipe over the muffler outlet and place the hangers into the factory grommets. From the rear of the vehicle
slide the tailpipe over the axle while holding the rear differential vent hose out of the way. Slide a supplied 3” clamp
over the inlet of the tailpipe. Pre-tighten the clamp. (See Fig’s P, Q & R)
Note: Using a soapy solution on the grommet hole will make the job easier.
4 Slide the tip assembly onto the end of the tailpipe. Snug the clamp at this time. (See Fig’s S, T & U)
5 Adjust all components to attain clearance to surrounding parts. Starting from the front of the exhaust system
tighten the spherical clamp nut to 21 ft-lbs and all nuts on pipe clamps to 35 ft-lbs using a torque wrench. Torque
the tip clamp to 16-20 ft-lbs.
6 It is strongly suggested that all clamps be checked and tightened after road testing the vehicle once the system
has cooled.

NOTE: During cold weather start-ups, you may experience an exhaust sound that is deeper and louder in tone than
usual. This is temporary and will diminish to normal levels once your engine has reached its normal operating
temperature.
NOTE: Immediately following the installation of your exhaust system, you may experience a trace of smoke after
initial start-up. DO NOT be alarmed. The smoke is caused by the burning of a small amount of forming oil residue
used in the manufacturing process.
