5. Setup and Installation
Preparation:
- Park the vehicle on a level surface and engage the parking brake.
- Allow the exhaust system to cool completely.
- Safely lift the rear of the vehicle using a lift or jack stands to provide adequate working space.
- Locate the factory axle-back exhaust section.
Removal of Factory Exhaust:
- Apply penetrating oil to the factory exhaust clamp and hanger bushings to aid in removal.
- Using a socket wrench, loosen the clamp connecting the factory axle-back section to the mid-pipe.
- Carefully remove the exhaust hangers from their rubber isolators using a pry bar or exhaust hanger removal tool.
- Once all clamps are loose and hangers are free, carefully remove the entire factory axle-back exhaust assembly from the vehicle.
Installation of RED ROCK Exhaust:
- Position the new RED ROCK axle-back muffler assembly under the vehicle.
- Insert the hangers on the new muffler assembly into the factory rubber isolators.
- Slide the inlet pipe of the new muffler assembly onto the mid-pipe, ensuring a snug fit.
- Install one of the provided exhaust clamps over the connection point between the new muffler assembly and the mid-pipe. Do not fully tighten yet.
- Install the two black exhaust tips onto the dual outlets of the muffler assembly. Use the remaining two clamps to secure them. Do not fully tighten yet.
- Adjust the position of the entire exhaust system to ensure proper alignment and clearance from other vehicle components. Ensure the tips are centered and level.
- Once satisfied with the alignment, progressively tighten all exhaust clamps to the manufacturer's recommended torque specifications.
- Double-check all connections and hangers for security.

6. Operating Instructions
Initial Start-Up and Inspection:
- After installation, lower the vehicle safely.
- Start the engine and listen for any exhaust leaks. Leaks can often be identified by a hissing sound. If leaks are detected, re-tighten clamps or adjust connections as necessary.
- Allow the engine to run for a few minutes to reach operating temperature. The exhaust system may emit a slight odor as it heats up for the first time; this is normal.
- Perform a visual inspection to ensure adequate clearance between the exhaust system and all other vehicle components (e.g., suspension, fuel lines, body panels).
- Drive the vehicle for a short period, then re-check all clamps for tightness after the exhaust has cooled.
7. Maintenance
- Regular Inspection: Periodically inspect the exhaust system for any signs of damage, corrosion, or loose connections. Check rubber hangers for wear or cracking.
- Clamp Tightness: Re-check the tightness of all exhaust clamps every 3,000-5,000 miles or during routine vehicle maintenance.
- Cleaning: The black tips can be cleaned with a mild automotive cleaner and a soft cloth to maintain their appearance. Avoid abrasive cleaners.
- Corrosion Prevention: While made from durable 409 stainless steel, regular cleaning, especially in areas exposed to road salt or harsh chemicals, can extend the life and appearance of the system.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Exhaust Leak | Loose clamp, improper pipe seating, damaged gasket (if applicable). | Tighten clamps, re-seat pipes, inspect for damage. |
| Rattling Noise | Exhaust system contacting vehicle chassis, loose hanger, loose internal muffler component. | Adjust exhaust position for clearance, inspect hangers, consult technician if internal issue suspected. |
| Excessive Vibration | Misaligned exhaust, worn rubber hangers, engine/transmission issue (less likely). | Check alignment, inspect and replace worn hangers. |
| Tips not aligned | Tips not fully seated or clamps not tightened evenly. | Loosen tip clamps, adjust position, then re-tighten. |
