This procedure covers the removal and replacement of the tail pipe assembly on a 2014 Ram 2500 with 6.7L Cummins Diesel engine, including proper hanger and flange connections.

Warnings

Tools required

Parts

• Tail pipe assembly × 1 — Use OEM specification for 2014 Ram 2500 6.7L Diesel
• Exhaust flange gasket × 1 — Use OEM specification
• Rubber exhaust hangers × 2 — Replace if damaged or deteriorated

Preparation

1. Ensure engine and exhaust system are completely cool to the touch
2. Park vehicle on level surface and apply parking brake
3. Place wheel chocks at front wheels
4. Raise rear of vehicle using floor jack and support securely on jack stands rated for vehicle weight
5. Spray all exhaust flange bolts and hanger bolts with penetrating oil and allow to soak for 15-30 minutes

Procedure

1. 1

   Locate tail pipe connection points
   Identify the tail pipe assembly which extends from the muffler outlet to the rear exit point. Note the flange connection at the muffler and the rubber hanger locations (typically 2 hangers supporting the tail pipe). Inspect for any heat shields that may need removal for access.
2. 2

   Remove heat shield if equipped
   If a heat shield is present over the tail pipe flange connection, remove the mounting bolts using appropriate socket. Set heat shield aside for reinstallation.
   Torque spec

   Heat Shield Bolts10 Nm (7 lb-ft)
3. 3

   Support tail pipe assembly
   Have an assistant support the weight of the tail pipe, or use a jack stand with block of wood positioned under the tail pipe to prevent it from falling once disconnected. The tail pipe assembly can be heavy and unwieldy.
4. 4

   Remove flange bolts at muffler connection
   Using 15mm socket, remove the exhaust flange bolts connecting the tail pipe to the muffler outlet. There are typically 2 bolts securing this connection. If bolts are severely corroded, apply additional penetrating oil and allow to soak, or carefully apply heat with propane torch if safe to do so.
5. 5

   Separate flange connection
   Once bolts are removed, separate the tail pipe flange from the muffler flange. Use a pry bar or rubber mallet to gently break the seal if stuck. Remove and discard the old flange gasket. Be careful not to damage the muffler outlet flange.
6. 6

   Disconnect tail pipe from rubber hangers
   Slide the tail pipe outlets out of the rubber exhaust hangers. This may require twisting and pulling motion. Use penetrating oil on the hanger interface if stuck. Inspect rubber hangers for cracking or deterioration and replace if necessary.
7. 7

   Remove tail pipe assembly
   Lower and remove the tail pipe assembly from the vehicle. Set aside for disposal or core return if applicable.
8. 8

   Clean flange mating surfaces
   Using wire brush, thoroughly clean the muffler outlet flange surface, removing all old gasket material, rust, and carbon deposits. The mating surface must be clean and flat for proper seal with new gasket.
9. 9

   Install new flange gasket
   Position the new exhaust flange gasket onto the muffler outlet flange, aligning the bolt holes. Ensure gasket is properly seated and oriented correctly.
10. 10

    Position new tail pipe assembly
    With assistance or using jack stand support, position the new tail pipe assembly into place. Align the inlet flange with the muffler outlet flange and gasket. Insert the tail pipe outlets into the rubber exhaust hangers, ensuring proper routing and clearance from frame, fuel tank, and suspension components.
11. 11

    Install and torque flange bolts
    Apply anti-seize compound to the threads of the exhaust flange bolts. Install bolts finger-tight, then torque in a cross-pattern to specification using torque wrench. Verify flange connection is properly seated and gasket has not shifted.
    Torque spec

    Exhaust Flange Bolts45 Nm (33 lb-ft)
12. 12

    Reinstall heat shield if equipped
    If heat shield was removed, reposition it over the flange connection and install mounting bolts. Torque bolts to specification.
    Torque spec

    Heat Shield Bolts10 Nm (7 lb-ft)
13. 13

    Verify tail pipe alignment and clearance
    Visually inspect the entire tail pipe assembly to ensure proper alignment, adequate clearance from all vehicle components (minimum 1 inch), and that rubber hangers are properly seated. Adjust position as needed before final verification.

Reassembly

1. Double-check that all flange bolts are torqued to specification and anti-seize was applied
2. Ensure tail pipe has adequate clearance from fuel tank, spare tire, frame rails, and suspension components throughout full suspension travel
3. Verify rubber exhaust hangers are properly engaged and not twisted

Verification

• Lower vehicle from jack stands and remove wheel chocks
• Start engine and listen for exhaust leaks at the flange connection - there should be no hissing or ticking sounds
• Visually inspect flange connection while engine is running for any visible exhaust gas escaping
• With assistant observing, rev engine moderately and verify no excessive movement or contact of tail pipe with vehicle components
• Take vehicle for short test drive and verify no exhaust rattles, contact sounds, or exhaust odor in cabin
• After test drive, re-inspect flange connection and verify bolts remain tight
