How to Install Gibson 3 in. / 2.25 in. Dual Sport Aluminized Cat-Back Exhaust - Dual Side Exit

Installation Time

2 hours

Tools Required
  • 1/2", 9/16", 15mm wrenches & sockets
  • WD-40
  • hacksaw
  • jack stands

When installing this exhaust system make sure to use proper safety precautions. Use jack stands when working under the vehicle, set parking brake, block tires and use safety glasses and gloves. Allow exhaust to cool before attempting installation. Severe injury or burns could occur if safety measures are not taken.

1. Disconnect the negative battery cable before removal of OEM exhaust. This will allow the computer to reset and recognize the new exhaust. Lay out the exhaust on the floor so it looks like the drawing and compare parts with manual.


2. To remove stock exhaust, unclamp it at the ball flange behind the Y-pipe. Make sure to leave all rubber grommets in the factory location. You will re-use stock clamp. For easier removal of exhaust, cut behind the muffler. Use WD-40 to remove hangers from grommets.


Next, install headpipe #A into the factory pipe. Insert welded hanger into the rubber grommet. Do not tighten


4. Install muffler #B with inlet towards Y-pipe. Use jack stands to support the muffler. Use clamp #F to secure the muffler to headpipe. Do not tighten. Muffler outlets will be level


5. Make sure muffler outlets are level before installing tailpipes. Now install passenger tailpipe #C. Insert welded hangers into rubber grommets.


6. Now install driver side tailpipe #D. The spare tire may need to be loosened and pushed to the driver side to allow for clearance. Use bolt kit #H to attach both tailpipes together.

7. Using clamps #G secure both tailpipes to the outlets of the muffler. Rotate tailpipes to best fit your truck.


8. Install stainless steel tip. Clamp down. When you have everything in place, firmly tighten all bolts and clamps down securely. Use stainless steel cleaner weekly to prevent tip from discoloration. Inspect all fasteners after 25-50 miles of operation and re-tighten as necessary.

GIBSON EXHAUST systems are designed on a factory stock vehicle
Any aftermarket products installed could increase the sound levels of the exhaust.
Make sure there is a 1” clearance from ALL rubber brake lines, shock boots, lines, tires, etc. to prevent heat related damage or fire.
