General Installation Practices

1. Before starting work, familiarize yourself with the installation procedure by reading all of the instructions.

2. The exploded view (Figure 1) provides only general guidance. Refer to each step and section diagram in this manual for proper instruction.

3. Throughout this manual, the left side of the vehicle refers to the driver’s side, and the right side to the passenger’s side.

4. Disconnect the negative (ground) cable from the battery (or batteries, if there are two) before beginning work.

5. Route and tie wires and hoses a minimum of 6” away from exhaust heat, moving parts and sharp edges. Clearance of 8” or more is recommended where possible.

6. When raising the vehicle, support it on properly weight-rated safety stands, ramps or a commercial hoist. Follow the manufacturer’s safety precautions. Take care to balance the vehicle to prevent it from slipping or falling. When using ramps, be sure the front wheels are centered squarely on the topsides. When raising the front of the vehicle, put the transmission in park (automatic) or reverse (manual), set the parking brake, and block the rear wheels. When raising the back of the vehicle, be sure the vehicle is on level ground and the front wheels are blocked securely.
   CAUTION! Do not use floor jacks to support the vehicle while working under it. Do not raise the vehicle onto concrete blocks, masonry or any other item not intended specifically for this use.

7. During installation, keep the work area clean. Do not allow anything to be dropped into intake, exhaust, or lubrication system components while performing the installation, as foreign objects will cause immediate engine damage upon start-up.

Highly recommended tools and supplies:

• Foot-pound torque wrench

Monster Exhaust System Installation

1. Disconnect the negative (ground) cable from the battery (if there is more than one battery, disconnect both negative cables). Secure the cable so it cannot accidentally come in contact with the post.

2. Raise the vehicle and support it securely with properly weight-rated safety stands, ramps or a commercial hoist. Take care to balance the vehicle to prevent it from slipping or falling. When using ramps, be sure the wheels are centered squarely on the topsides. Place the transmission in park (automatic) or reverse (manual), set the parking brake and securely block the wheels that are on the ground.
   CAUTION: DO NOT WORK UNDER ANY VEHICLE SUPPORTED ONLY BY A FLOOR JACK. SEVERE INJURY MAY RESULT.
   WARNING! The following step may require the use of a torch and/ or saw. Proper safety equipment should be used. Failure to use proper safety equipment may result in severe injury.

3. From under the vehicle remove the factory exhaust starting at the rear of the muffler. Remove the tailpipe by removing the two (2) nuts connecting the muffler to the tailpipe. Remove and retain the two (2) M8x1.25 bolts retaining the rubber hanger on the rear tailpipe hanger. Remove and retain the rubber hanger. Remove the tailpipe assembly from the vehicle (See Figure 2).

4. Remove the muffler and Y-pipe assembly by removing the four (4) M8x1.25 nuts from the studs of the two (2) flanges after the 3rd and 4th catalytic converters. Retain these four (4) nuts for reassembly (see Figure 3).

5. Remove and retain the two M8x1.25” factory bolts holding the factory Y-pipe rubber hanger and detach the rubber hanger. Remove the Y-pipe and muffler assembly.

6. Align the factory rubber hanger onto the Banks hanger plate and secure with the supplied 5⁄16” bolts, nuts and washers (see Figure 4A).

7. Align the hanger plate assembly onto the original location of the hanger such that the rubber hanger is on top of the plate. Loosely reinstall the two (2) factory bolts through hanger plate into the vehicle frame.

8. Install the two (2) gaskets onto the right and left side catalytic converter flanges. Install the Y-pipe flange onto the right side catalytic converter flange. Lightly tighten the factory two (2) M8x1.25 onto the factory studs.

17. With the exhaust positioned properly, begin to tighten the clamps and hardware starting with the ones closest to the front of the vehicle and working your way back. Torque the exhaust clamps evenly to 35 ft-lbs. Make sure that each slip is fully inserted (+/- 1⁄2”). Torque the factory M8 hardware to 22 ft-lbs. Torque the 5⁄16” hardware to 19 ft-lbs.

18. Install the supplied heatshield blanket onto the y-pipe and left head pipe connection. Wrap the heatshield around the clamp and pipes to protect your transfer case or gas tank (if applicable). Secure wrapping with the three (3) tie wraps (see Figure 3).
