REMOVAL INSTRUCTIONS

1. Using the ratchet and 15mm socket, loosen the clamp in front of the passenger side flange connection.| 2. Using the 13mm wrench, loosen the two nuts at the driver side flange location. Set aside the spring nut assemblies to be reused during INSTALL STEP 5.

reused during INSTALL STEP 1. Remove the ground clip from the passenger side front hanger of the rear muffler| 4. Using grommet pullers or similar device, remove the front hanger grommets from both rear mufflers.
NOTE: The use of soapy water solution will aid in the removal and later installation of the hangers in the factory grommets.
|
5. Using the ratchet and 15mm socket, loosen the clamp on the inlet pipe to the driver side rear muffler.| 6. Remove the driver side rear muffler inlet from the axle pipe connection.
NOTE: The use of penetrating lubricant spray on the pipe joint may aid in removal.
|

WARNING! DO NOT SKIP THIS STEP!
It is recommended to apply the anti-seize lubricant to the threads ONLY of the clamps and flange bolts. Failure to follow this procedure can cause nuts to seize on clamps and potentially destroy threads.
After applying anti-seize lubricant, be sure to thoroughly clean your hands, as lubricant will tarnish stainless steel.
All clamps should be tightened using a properly calibrated Torque Wrench. Using an air impact gun will damage the clamp and reduce its ability to effectively seal the joint. It may also cause the joint to separate, thereby causing damage to your exhaust system and to your vehicle.

NOTE: Align all clamps so that the center of the clamp bolt is 90 degrees from the notch in the pipe.

24. At this time, visually inspect the exhaust system position, tip alignment, clamp orientation, and exhaust pipe clearance. Make any necessary adjustments at the slip fit joints and flange connection.
25. Torque all supplied flange mounting hardware to 35 ft-lbs. at the two flange connections.
26. With the tips held in the desired location, start at the front of the vehicle, and tighten the nuts on the clamps. Torque all clamp nuts to 45 ft- lbs. (61 N-m) on the 2.75” clamps.

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.
NOTE: It is strongly suggested that all clamps be checked and tightened after road testing the vehicle once the system has cooled.
